I have a computer with a funky power supply. It won't turn on until
something in it is warm enough. I have ordered another but a new
problem has cropped up in this computer. The monitor said there was no
signal even though it was connected to the computer. Thinking it might
be dirty contacts I removed the video card and the monitor cable,
cleaned the contacts, and plugged everything back in. No joy. I
unplugged the computer and let it sit about an hour. Plugged it back
in, tried turning it on but had to wait a few minutes for the power
supply to start fully functioning and when it did the computer worked
properly and the monitor had a picture. I left the computer on for
several days and everything worked fine until this morning when once
again the monitor reported no signal and once again no picture. So I
removed power from the computer and removed the video card. I put the
card in the fridge for abou 1/2 hour. Then I put the card back in the
computer, plugged the computer back in, waited the few minutes again,
and now it all works fine again. So, should I start shopping for a
video card too? Could the flaky power supply be affecting the video
card too?

Some of the computers have been known to have capacitors that go bad
after a few years. The classic symptom is the computer comes on when
hot.

Look at the larger capacitors that have leads going through the board.
If the top of them is rounded off like a dome they are bad. They should
be flat. This could be on the motherboard or video board.
