No vid, no beeps, cpu fan blowing hard. NOW prob's fixed - but how?
Posted on 2013-05-12
A Gateway 500gr desktop computer (using onboard video) was working fine for years. Suddenly, it had no video signal, no mainboard startup beeps, and the CPU fan was blowing hard.
I removed the one PCI card (a phone modem), and it booted up correctly. (Problem gone).
Just or good measure, I reset the CMOS. The computer still booted correctly.
Then I reinserted the modem PCI card, and the PC is still booting correctly (Problems still gone!)
What do you thinks going on? Will the problem come back? (It's important because I want to return the PC to its owner.) Should I keep the unused Modem card OUT?
I've heard that a PSU can go bad "just a little" so that it can only power so many parts - which would explain why the PC worked when a part was removed. But NOT when I put it back in. Unless PSU's can be just "on the edge" like that, going back & forth...
(One could suspect resetting CMOS fixed it, but it booted before that.)
