Computer won't turn on at all.

[Tomdeaser]

I shut my computer down to install a disk drive. Upon installation, I attempted to turn the computer on, but nothing happened. No Power light or anything. Do you know guys know what could be the cause because I've tried everything I can think of (resetting the CMOS and checking the power supply is being given power). The disk drive is not in there anymore, as I removed it, thinking that it was the source of the problem.

Try this:

1) kill power to the PC by unplugging it from wall socket.

2) Press & hold in the computer's front power button for at least 10 seconds to purge stored power from the PSU.

3) Now plug the computer back in at the wall plug.

4) Try starting your PC now.
