Order that while you start your RMA process.
edit: hey also try plugging it into a different wall outlet now that we know you were turning it off, before. Just to be sure. Or just verify it works by plugging something else into it.
Could be, maybe try a PSU tester? Those can be fairly cheap.

At this point, my first step would be verifying that the monitor is processing signal correctly by attaching it to another signal source.
Next, I would check the power supply. You can either take the time to do it with a multi-meter, pin by pin, or you can drop the money for an ATX power tester.
If your monitor is good and your power supply is good, but you still can't get access to the bios screen, your CPU/Main board are probably the issue.
