Yep. Doesn't post checklist:
Everything but replacing the CPU would take a few minutes at most. All the tools necessary can be taken with you to someones home in a small kit (tools to open case, tester, multiple dimm types).
If you actually got all the way to replacing the CPU (assuming the computer didn't give you the beep code for bad memory), you would just inform the customer that it seems it's either a bad motherboard or bad CPU but that you would need to take it back to the shop for further diagnostics. If it's in your shop and not at home, this would be a really really quick 15 minute job.
Assuming it was off when it got wet, it may be ok if you let it dry out completely. Of course modern power supplies are not really off, unless they are unplugged. Even then there is a small amount of current being supplied to the real time clock via the coin cell battery on the motherboard.
If it does not start up when dry it is possible it is just the power supply that is dead / blown fuse. The motherboard and cards / drives may still be fine.
The fuse in the power supply is not considered user serviceable so don't open it. If it is dead just toss it. They make ATX power supply testers and you can find them for cheap on Amazon.

Here is a power supply tester
it's hardly relevant, but that last one is there because those plastic packages are annoying and sometimes the thing inside those clamshell packages are used for PC repair, such as a flash drive. it also has a box cutter, a little screwdriver you can use as a backup, and the clippers work really well on zip ties, which can sometimes be useful with PC parts, as wires are sometimes zip tied together.
everything else is basically all you'll need to diagnose and fix any problems you may have with a PC. as long as the PSU connectors and motherboard are working, you can figure out any other hardware failure. Dr. Web will cure almost any viruses you can't kill in safe mode with Malwarebytes, and Ultimate Boot CD has many diagnostic tools that from my experience, can help pinpoint nearly any other issue.
I feel like I've forgotten one of my other diagnostic tools. I might be thinking of my PC Login Now disc and my XP Black CD. but I can't legitimately link you to those. most subreddits frown upon linking to anything even remotely related to piracy. I think I covered everything else.
and depending on how advanced with repair you plan to go, you might want a soldering kit as well, but I doubt you'll do anything on that level. I don't even solder anything, and I plan on doing computer repair for a living.
I wouldn't doubt it as the CX PSUs are pretty horrible.
What light exactly are you referring to though? The power button light on the case? No other lights come on on the motherboard or anything? No fans turn on (literally none of them?)? If the PSU was completely dead you'd likely see no lights at all, but that doesn't mean the PSU isn't the problem.
You can test the PSU with paperclip method to confirm if it's indeed the problem or if you want to fork up a few dollars you can buy a PSU tester. Something like THIS would work.
Your friends psu was for sure 100% good ? Check for 12v and 5v coming from yours. You can get a tester for this on amazon for about 12$. https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
If you still get no video output when using the motherboard vga then it's either the PSU or the motherboard.
Power supplies can turn on, make fans spin etc but still be broken. If you are not in a hurry to get it fixed, here is a simple, cheap but essential tool you can order online to tell if the PSU is working:
Power Supply Tester
If the PSU is bad, it is probably worth it to replace it. If the mobo is bad then the cheapest way would be for you to replace it yourself.
If you take it to a shop you should call a few places and get quotes. My guess is somewhere in the $150 - $300 price range depending on the mobo and what they charge for labor.
Once you know the quoted cost of repair you can decide if it's worth fixing or replacing.
You could check continuity on each pin with a multimeter.
You could also use a Power Supply Tester like this one.
Something like https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S but his had a little LCD screen, and the model didn't have good reviews. Closer to https://www.youtube.com/watch?v=T-jG3vqRQHM but still not what he showed me a picture of.
It's a very simple device that has a plugin for the PSU cables and checks the voltages.
Here is an example,
https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
There is a little tool you can order off amazon to check PSU power, but i forget the name. Lemme see if i can dig up a link
:edit: here ya go! Something like this

Sometimes your motherboard can get stuck in a weird state. Turn off the power at the power supply if it has a switch, if it doesn't, unplug the computer. Press the power button on the PC a few times with the power off/disconnected, then plug it back in/turn it back on and press the power button again.
If it still doesn't work, you might have a bad board or PSU. PSU testers are cheap and will help you narrow it down before you start replacing things.
I would use a digital multimeter.
There's also a PSU tester. I've never used one but I've seen it recommended here a few times.
A cheap multimeter should be available at your local hardware or auto parts store.
For example:
http://m.lowes.com/pd/Morris-Products-Digital-Multimeter-Meter/4738850
There are also purpose built power supply testers.
http://www.amazon.ca/gp/aw/d/B005CTCD6S/ref=mp_s_a_1_1?qid=1457390512&sr=8-1&pi=SY200_QL40&keywords=atx+power+supply+tester&dpPl=1&dpID=51F4joHuY5L&ref=plSrch
I guess for 8 bucks, this. Lots of choices on amazon actually, just search power supply tester.
Still though even for that cheap at that rated wattage, I would just like to put it out there I wouldn't trust a used PSU from a stranger even if I have an implement to test it.
If your shop doesn't already have one, one of these (or one like it) will save you so much hassle. I do craigslist computer work, and didn't know that these things existed. I got one recently and it is so wonderful.
There are relatively inexpensive PSU testers available, so that might be a start. Either that, or perhaps a local computer shop has the appropriate testing equipment on hand.
Do you have the make/model for that pc? or at least a link to the specs of it?
I'm banking on your PSU is dying/dead. You may be in the "dying" phase right now where your 550w is barely pushing enough amps and when it drops low enough, your PC shuts down.
I would also just double check all your PSU connectors, unplug, blow, then replug in and make sure they all snap in
edit here is an example of a PSU tester: link
Sometimes they can be useful to diagnose a PSU, however, if your PSU is having problems providing amps, if may report that everything is okay. Unfortunately there isn't a good way to "put a load" on the PSU besides simply running your PC.
When something like this happens I usually turn to a trusty power supply tester to help clear the fog. They look like this and they're very cheap.

Have you tried testing GPU in another computer? If you can I'd recommend that to see if it really did fry the GPU. If it did, definitely bad psu. Swap that bad boy out. Also swap the Cable as it could have been fried as well.
If GPU is working fine in another computer, then it's going to be a bigger headache. Probably need to replace Mobo. Though this is unlikely the culprit. I'd almost bet money on bad PSU.
If you can, get a PSU tester. They're like $10-$20 and are very good for this kind of thing. Allows you to make sure it's PSU before hooking up a replacement part and frying it too.
Edit: Here's a cheap PSU tester. $11. Might be worth it to get it and test PSU first. Unless Corsair is willing to swap it out anyway. If they aren't, get that and test it. If you tell them you tested it with a PSU tester and it tests bad, they will not balk any about swapping it out.

I use this one. There is even a YouTube video somewhere on how to use it. It's pretty easy
https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=mp_s_a_1_4?ie=UTF8&qid=1541528951&sr=8-4&pi=AC_SX236_SY340_FMwebp_QL65&keywords=hde+power+supply+tester&dpPl=1&dpID=51oGO0bfPqL&ref=plSrch
First thing I would try is taking out one of the RAM sticks, see if it works. If it doesn't, swap the one that's in there with the one you took out (basically only leave 1 RAM stick in) and see if THAT works.
If it doesn't, you may wanna try a new power supply, or buy a power supply tester.
Also, if your motherboard has a built-in display, take out the Radeon card and plug the monitor directly in to the onboard display and see what happens.
If ALL of that fails, it's probably the motherboard.
https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S get one of these and test the PSU. The paperclip test won't help as the PSU is able to power the LED.
Could be a faulty PSU or the connection of PSU to motherboard. Could also be dirty power coming through the wall. Either get a PSU tester (example: https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S ). Make sure you arn't getting power brownouts/sags from the power provided through your home. Are you plugged into a line conditioner or UPS?
To be fair, most people don't know how to turn on a PSU without it being connected to the motherboard and case.
To OP, you need either a PSU tester (they're cheap) or you can ghetto-test it with a paperclip or anything else thin, bendable and conductive
I found out when my pc started turning itself off. I had to unplug a few things power wise then pc turn itself on. By then, its considered "too late" and should of replaced it sooner, just didn't have the money.
SO you don't really want to wait that long if its starting to do the above but if it isn't, you can buy a power supply tester which if any lights aren't green on it, means PSU is dying. I would recommend this if you aren't super tech smart to mess with volts and/or don't want to waste money on a psu and find out its something else.
or a psu tester

Follow the power is the best method of troubleshooting.
First check if the power supply works. You can do this by either getting a power supply tester or shorting out pins 14 and 15. If the power supply doesn't start, it's dead.
If after replacing the power supply, your computer still doesn't start, take out your motherboard and start looking for black stains on or near the surface and through-hole mounted components. Start at the power connectors on the motherboard (CPU and ATX) and work your way from there. You will need good lighting and good eyesight (or magnifying glass).
Any black stains means an exploded component and should be replaced.
The same will hold true for any other peripherals, especially video cards which take power directly from the power supply.
Good luck!
I know you probably want a fast solution, but if you do not have a power supply you can substitute you will need something like this: http://www.amazon.com/eForCity-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=cm_cr_pr_product_top
I do not have personal experience with that one, but I do own this: http://www.amazon.com/gp/product/B002R06PGE/ref=wms_ohs_product?ie=UTF8&psc=1
Even if you don't need a tester right now, I advise having one on hand, especially if you have multiple PCs to maintain. In my case, I have lotsa family and friends I help, and a PSU tester has come in handy over the years.
Theres plenty of these things. Here's a cheap one.
Ok I have a question about this motherboard, It is an Asus A8n-e. It has a 20 pin power motherboard connector and a 4 pin power connector. Is the 4 pin 100% needed to supply enough power to this motherboard? The reason why I ask because I bought a power supply tester and when I connected the 20 pin only the +5 led came on and when I plugged in the other power cables such as the HDD, 4 pin, no other light came on.
So what I did next was use the power supply tester on my buddies power supply and everything lit up for his connectors and every other cable we tested.
Is the 4 pin power connector needed to power up the motherboard correctly? and would it cause the motherboard to turn on by itself? or would this still be the effect of a short circuited motherboard. I ask this because when I used my buddies PSU we did not plug it in and only used the 20 pin.
Thank you again
Will this give me more definitive results with the PSU?
https://www.amazon.com/gp/product/B005CTCD6S/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
no the system doesnt make a noise fan dont spin nothing
This is what I got coming.
Not 100% necessary, but cheap and useful. http://www.amazon.com/gp/aw/d/B005CTCD6S?pc_redir=1404153821&robot_redir=1
sounds like PSU, you can buy a cheap tester and test it yourself.
https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
Maybe something like https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S from an online or local store could help. Otherwise I'm not sure what else to do. Edit: Oh that's just for 24 pin maybe something similar though.
$8 bucks on Amazon. Microcenter used to have them too. Go nuts on it.

Interesting, I might try this with a paperclip as suggested by someone else, and if it spins up I can test further with a multimeter. Just to be clear, I searched on amazon and found a PSU Tester for $7... is that the same as a multimeter? Here's the link to it:
https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=sr_1_4?ie=UTF8&qid=1526079288&sr=8-4&keywords=psu+tester
Thanks!
You may confirm the PSU is dead with a tester like this one (can't beat it for $7!)
DO NOT open the PSU unless you know exactly what you're doing.
PSUs go bad, and the best thing is to just replace them. If the tester confirms there's no power going through, you'll have to buy a new one. If there IS power, then the board may be the problem.
Ok. Well this is a last check. Get a power supply tester or something similar. If it powers up, your supply isn't the problem. Modular supplies have plugs for the cables to go into on the unit. Non modular are ones that have all the cable soldered inside, meaning you may have extra that you don't need sitting in the case. Google it and you'll see pictures of what I mean. Other than that, they are the same. Recommend a power supply? Sure. This is what I use: Corsair TX 750. It's not the best there is on the market, but it's reliable and efficient. That's the best I can do flying blind right now.
I don't know about software, but there are tools like this:
https://www.amazon.ca/PC-Power-supply-tester-LED/dp/B005CTCD6S
I would get a cheap PSU tester or use a multimeter to check the voltages.
You could get a PSU tester
I guess if you want to rule out power issues, you can get something like this:
http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
I use a different type, but it will tell you if the power supply is outputting the correct voltages at your house.
If it isn't that, then it must be EMI. What is the case made of?

Sounds like a Power Supply Issue to be honest. Easiest way to verify it's not a power supply issue is to buy a power supply tester like this ( http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S ) for about $7. So helpful in diagnosing issues when you can be sure if the power supply is working or not.
If the power supply passes at that point, it's either the Motherboard or the CPU. From then look at your capacitors and make sure they all look good and see if you can spot anything wrong.
Typically based on my experience it's usually the motherboard and not the CPU, but without testing your Power Supply (or Using a known good Power Supply). You won't know for sure.
Also as an additional note I have seen power supplies still turn on when they were not working correctly so just because the fan spins does not mean it is working properly.
Is there a way to test the PSU without going and buying a tester?
If it comes down to testing the GPU, I'll see if my brother-in-law has a spare GPU or will let me borrow his GPU. May not after hearing what happened to mine. :)
As you said no beeping, then it's not a memory issue. If the motherboard works, your next step is to check your power supply.
I recommend getting a cheap but efficient power supply tester and see if the throughput is correct. Otherwise, a replacement power supply doesn't cost too much.
If that doesn't work, it's most likely a CPU issue, which will be pretty expensive if you have to replace it, I recommend taking your computer in to a respected hardware shop to see what they can do or have to say about it before making any expensive moves.
Any local shop should do it for free or you can purchase the tester yourself. It's a quick 5 second process:
http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
(I'm not advocating that tester in particular, just showing what it is.)
A PSU tester is probably your best bet.
>my PC that’s 5-6 years old
What brand and model of power supply does this pc build have? The power supply could be faulty or failing but the model and brand could be a better indication than guessing.
Buying a power supply tester is also a very good method for testing for a faulty power supply and these are cheap to buy on amazon or take your tower or psu to a computer repair shop locally and ask them to test your psu.
A GPU making buzzing sounds is a good sign of a faulty or failing GPU or possible power supply instability issue.
Cheaping out on poor quality power supply for a pc build is never worth the compromise
https://www.youtube.com/watch?v=qB35OVe35LM
https://www.youtube.com/watch?v=hLWFJ91gKSo
id start with testing the power supply with a tester like this: https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S If the PSU checks out, check all your cabling and mobo manual to make sure any auxilary power plugs are being connected. If the fans arent coming on, and no power led's anywhere, then its either your power supply (less likely) or power cables not connected correctly (more likely). Also, seems simple, but check the wall outlet you are using to make sure you actually have power to the pc.
Recheck all physical connections from your PSU to your hardware and, if possible, test your PSU with something like this if you've got one.
If you can test the specific outlet you're using, too, then that's a bonus
There's not really a way to test it. Usually though when a motherboard goes bad fans and the board will at least get power but not posting at all is weird for a motherboard and is usually related to the psu.
I would try the PSU alone first by disconnecting it from the motherboard and shorting the correct pins. (Usually a green wire and black wire you need to short together to get the psu to turn on) You'll definitely need to look into your specific model and make sure you're shorting the correct wires though so the psu doesn't catch on fire.
Or you can buy something like this which shorts the correct wires for you.
https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=sr_1_5?ie=UTF8&qid=1499978021&sr=8-5&keywords=power+supply+tester
Have you made sure the outlet still works?
You've already tried turning it on, so now you gotta test the PSU on it's own. Need a digital power supply tester or use a paperclip to test it outside of the case. Some PSUs come with a 24pin adapter that you can plug in that's the same as the paperclip method.
The paperclip method should force the PSU to turn on when the switch is flipped. If it does not turn on, then we found your problem.
Actually what I'll do is buy a PSU tester since I don't need to have it connected to my PC to use it. If the PSU is bad then I might be able to get away with RMA'ing the PSU with EVGA to get a new one. If the tester shows the PSU is good then I'll reinstall W10. If reinstalling doesn't work then I'll have to hope I just need to update the bios and re-overclock the CPU instead of having to replace the board and redo my cable management.
For that, you need one of these
There's probably ones available via Prime, or even locally if you have a good computer shop. Usual average is $20-25 for a decent one. Small enough to always have in your bag; a failing PSU can exhibit very odd symptoms and this thing should tell you if there's an issue.
Then it sounds like a dead mobo or PSU. If you have someone who has a PSU you can borrow you can check that, otherwise a power supply tester may be a worthwhile investment.
Diagnosing the PSU is hard, and keep in mind that a failing PSU can take other components with it, so if the PSU is the root cause, you could still end up with "multiple component failure" even though you've now replaced the Mobo / CPU and RAM.
You can use a multimeter or purchase a dedicated PC PSU tester like this one.
I haven't had to test a PSU on almost 20 years, and used a multimeter when I did, so I don't know the commonly accepted way to do so now.
Also, you might want to see if any of your local PC repair shops will let you borrow / rent a PSU (and maybe some bench time) to diagnose the issue. Using a spare is often the easiest way to rule out a particular component, which is why I have bins of shit my wife has been begging me to throw out since 2005... but one day... one day I will need a Firewire cable, or an an extra three-plug component video cable, and then who will be laughing...? Right...?
You could pick up a tester to make sure all the rails are running as expected:

Lol what? motherboards have a "core" rating? since when?
as mentioned in OP I have a :
CPU: AMD Ryzen 7 1700X Eight-Core @ 16x 3.4GHz [29.0°C]`
and Then my motherboard is:
https://www.asus.com/us/Motherboards/ROG-STRIX-X370-F-GAMING/
Something like this? https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
what will that do since my computer can run benchmarked at 100% for weeks without issue? (genuinely curious)
Might be worth investing in a PSU tester before you go through replacing it.
Well, the only way that I know of to test a PSU is with a PSU tester, which is a handheld device like this. From my experience, this seems to be more power related, but without actually seeing it, its very difficult to tell.
I mean, maybe test the psu with [this] (https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S)
You would have to test them in another computer that supports them. Should be pretty easy for the RAM and GPU, will probably be more difficult for the CPU. PSUs have testing tools https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
Unfortunately speedfan isn't providing much useful voltage info, taking measurements is the only way to determine if it's healthy. I've never used one so I can't vouch for how effective they are, but there are inexpensive PSU testers available. Otherwise, if you know someone who can help you take measurements, here are some instructions.
Some other suggestions, in no particular order:
So you tried without the power strip and on a different circuit and it didn't go away? The problem your running into here is it's a fairly old system, so even if you're willing to spend some, is it worth it?
You could invest in a PSU tester they're pretty cheap. But I've never used one before so I can't say if it would show a fault related to your problem. Or take it in to someone, but the cost more than likely doesn't really justify it. You could phone around and see if any shops will diagnose for free. Doubt they will, but it's worth a shot I guess.
Do you have any geek friends. I know I have a couple of backup PSUs just kicking around, so maybe a geek friend would have an extra one to troubleshoot with. Are you interested in eventually upgrading your system or is it still pretty useful?
If you are, you could always use the PSU in the future build. And to be quite frank, trying to replace that MB will be more trouble than it's worth IMHO. It'd be ebay and finding one that wasn't faulty would be hard. Or at least 50 bucks for brand new, if you can find a AM3+ board.
Edited: posted before I was finished writing. lol
In you have a DC Voltage meter test one of the PSU connectors that carries 12V. YouTube has tuts on how to do this.
​
If the PSU has an older 4-pin Molex drive power connector check pin 1 to ground - Pin 1 is +12V, pins 2 and 3 are ground and 4 is +5V. This is quick and easy if you have a meter.
If you don't have a voltage meter, you could get a simple PSU tester like this one that will check all voltages: https://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
​
Since you already replaced the PSU you would have to do the above tests with PSU in the case connected to the MOBO. If you aren't comfortable using a meter, get the PSU tester.
Having a high wattage (not voltage, they aren't rated in volts) power supply wont hurt a computer. There is a good chance that he got a dead on arrival power supply. Best bet is to get a power supply tester (this seems to be a decent and cheap one) or try it in another computer. If it is indeed dead it is likely not due to anything you guys did, sometimes they just come out the door and croak. If that is the case, it is time for an RMA.
With things like these. Though er might be another way but I doubt it
A blown PSU can indeed take out core components when they go. Power supplies usually have fuses to keep this from happening but I am not sure if all do.
The only way I know of safely testing it would be something like this
You can buy a PSU tester pretty cheap. Here's an example:
https://www.amazon.ca/PC-Power-supply-tester-LED/dp/B005CTCD6S
Also: Is it possible that your CPU is overheating due to failed heat sink compound?
Some no-name brand I bought in a store, very similar to this though.
http://www.amazon.com/Insten-24-pin-Power-Supply-Tester/dp/B005CTCD6S
Actually, rereading your first post, the PSU could be okay. You could try purchasing a tester to find out.
This might help to make sure your wiring job was correct http://www.amazon.com/eForCity-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=sr_1_1?ie=UTF8&qid=1398573072&sr=8-1&keywords=psu+tester
Thank you so much! I can only function with steps lol.
So by following the pin layout, it will direct me to connect, for example, pin 1 on the psu to pin 4 on the motherboard side?
Edit: And would [this] (http://www.amazon.com/eForCity-24-pin-Power-Supply-Tester/dp/B005CTCD6S/ref=sr_1_1?ie=UTF8&qid=1398573072&sr=8-1&keywords=psu+tester) help me check if I put the wires into the connectors in correctly?
Power supply tester, and if it shows good, then you pretty much know it's the motherboard.
Here's one for about $6, shipped, Prime.
If you don't have a multimeter you can try buying a psu tester.

Remove the PSU and try the paperclip test on it. If it turns on it may be ok. But, in order to test the voltages you would need a proper PSU tester, such as one of these.
https://www.amazon.com/dp/B005CTCD6S/ref=cm_sw_r_taa_x0TzxbR31JNCX
Usually between 10 and 25 dollars.
I've been working in the field for many years and you can test a PSU with a PSU tester or using a multimeter.

Are you overclocking at all? Also, what kind of CPU cooler are you using? Stock or aftermarket?
Have you booted into the BIOS to monitor your CPU temps?
Re seat all of your power connections, and try to boot back up. If it's still a no-go It's always handy to have one of these around:

I have had breaker trips destroy power supplies. It sucks, but the PS SHOULD have absorbed the issue and hopefully your hardware is safe.
I would recommend that you hook your machine up to a UPS. Even if it can only give you 10 mins or so of backup battery, it will clean the power (most of them have voltage regulation and sine wave regulators) and if you drop a breaker, it will keep everything alive.
Good Luck
I have something like this, ends all guessing so you can move on to the next thing...

you could fry the other system. A faulty PSU could just do nothing or it could cause serious damage. You are better off buying a power supply tester
