Video signal goes out within a minute or two.
I recently sold my old computer to a friend (who knows little about computers) and about a month later he tells me the video stopped working. He said after it went out it came back on once for about two minutes and since then the video didn't work at all.
So I got the computer from him a day or two ago to see if I could work out what was going on. I set it back up with the case wall open and tried to fire it up. All of the fans came on, video card fan was running fine. Everything "looked" to be getting proper power. But I noticed there was no motherboard beep when I hit the power button and I couldn't hear the hard drives spinning, though they are fairly quiet anyway so I'm not positive whether they were on or not.
After playing around with it for a bit I went to see a movie and when I walked away I disconnected the PSU from the wall and both power jacks on the motherboard. When I came back to the PC later and plugged it back into the motherboard it came on, with the motherboard startup beep off the board and video came on. But as he had said it loaded into windows and before I could really even click on anything in windows it went back out again. Fans and everything still running fine.
This computer is 3 or 4 years old, maybe a little more. And it has about a 25% over-clock on it so I imagine its drawing some hefty power off the 680w supply. It did run fine for its entire lifetime up until now, though its only been over-clocked since last March. Its been pushed pretty heavily since then though.
My initial thoughts were heat or a power issue. I've cleaned it all out (it had a LOT of dust built up) and I'm pretty sure its not a heat issue now (unless it already caused damage and this is the after effect.) I figure the power supply has some age on it and pushing that over-clock it could possibly be an issue there. But I'm trying to find out what others may suggest. I'm hoping to find another video card to try out and maybe another power supply as well.

It does a weeee bit better in safe mode. I loaded into Windows Safe mode and just let i sit while I was messing around on my own computer to see if it stayed up that way. It was on probably 10-15 minutes before it went out and back to needing to pull the motherboard power in order to boot it again.
Could that be some kind of fail safe trigger for a problem in the power supply?
