Hi, I recently installed a new 500w power supply, a stick of 1gb ddr2 ram, and a used 8600gt nvidia geforce graphics card about two weeks ago.

My computer has been fine until today - it boots up (there is a single beep after it is turned on) but there is no video. I made sure the dvi cable was secure, but there still seems to be no video.

When I tried to shut it off by holding the power button, nothing happened, except for the processor fan stopping. The only way for me to turn it off was to hit the power switch in the back.

I've tried googling this problem, but I have not found any problems identical to mine, so thanks for the help in advance!

Hi there!

Have you check you bios settings? there is an option in the bios setup for you to chose what display to be initialized first, it should be set on PCI-E or PCI-Express.

Unfortunately, although I hear the single beep, there is no video whatsoever, not even BIOS. I have tried combinations of two different video cards and two different monitors, and none of them were able to provide any video at all.

EDIT: For some reason there are no beep codes when it is turning on now. Also, the keyboard's caps lock/scroll lock lights do not seem to function. Possibly a PSU problem?

Why not put the old components back in (since they worked)...and then replace them, one at a time, with the new components.

Makes it a lot easier to troubleshoot problems which develop.
