PC will now power up
I got an pc that a usb flash drive was remove from the system and it locked up after that turn it off and then it would not power back up, the little green light on the back of the power supply comes on when I attach a power cable but when I hit the power button nothing happens also the little green lite on the power supply flashing a bit when the power button is hit ... would you say this board is fried? .. would u just replace the board or the cpu could be bad also?
Any time you are checking start up issues, you need to strip it and go to basics. By strip it I mean remove everything but processor.
If you unplug ALL drives, remove the ram sticks and remove all non-essential boards, like extra video cards, sound cards, modems, nics and anything but the primary video, if you have a video card and also have onboard video, remove the video card.
Now try to boot the system, if it's posting, it will give you a long beep indicating that the ram is missing.... this is good...
Next you power off and put the ram back in and try again... if it posts past the ram you will get a message that it cant find the hard drive.... again, you are making progress.... you want to see if something that is plugged in is causing no boot...
If however, the system does nothing when you try to boot it stripped, then the only other thing to do is test the psu... you can do this with a tester, or a multimeter. If this is the case, and you need the wiring diag to test the psu, let me know and I will get it for you.

is this power supply Bestec? i just had one with a flickering green light on the back
it WAS BAD -nearly all capacitors inside were bulging and leaking
note - sometimes they still power on a couple of times- but don't rely on that

Curiousity has me wondering.... what was the final outcome?
What make and Model is the PC in question?
Maybe unplug the power cable for about 30 to 45 seconds. Plug it back in and try the power button again.
