Specs: xp pro, 2.1/512DDR
Hi, This one has me really puzzled. I was checking yahoo mail and the screen suddenly went black. I rebooted and there was nothing at all on the screen but the keyboard lit up as if it was loading and all the fans were working.

I removed the vid card and tried another one, still nothing. Does anyone have any ideas on how to fix this problem?
Thanks

Is the PC desktop or laptop?

sorry, it's a PC, I thought by putting in home-built it would explain that :)

Did you try a different monitor or try that monitor on a different system?

What type of graphics interface are you using, AGP?

Do you have any PCI video cards you could try?

My first guess would be the AGP slot has quit on you, assuming you are using AGP.

Do you have integrated graphics as well?

The origional card is AGP, no onboard graphics, and yes I tried 2 other working PCI graphics cards.

Are you always using the same data cable to connect the monitor in all instances, including now?

If so, the problem may have something to do with one leg of the PSU. Probably the 12V. If you have a compatible substitute PSU I would try that. Also, check the 20/24 pin power to motherboard connector.

Inspect the motheraboard for any signs of bulging, leaking, burned, etc. components.

Well, thanks to Othehill, I opened up the box and did some inspection. This was a PC that was given to me so I never checked out the board before except for swapping out the vid card while troubleshooting..

This still has me puzzled....I noticed that one of the sticks of ram was only partially inserted so I was only using 500MB DDR for 4 months, not realizing the other wasn't seated. So after I reseated the ram, low and behold it all came on....I guess with the ram being as it was it was just a matter of time before something stopped. Thanks for getting me to inspect the MOB.

Sometimes it's the simplest things :)
