No signal from any GPU.
Feb 1, 2012, 6:52 PM
I'm helping a friend with his PC trouble.
Basically, I start up the PC. There is no signal. No response whatsoever. No beeping no anything.
All the fans are on, but there is no signal from GPU.
I tested the gpu on my own pc and it works. I tested my gpu on this pc and it still didn't work.
So. I guess it's something with the motherboard. (which has no integrated graphics)
I put in Ubuntu live cd, just to test for any response, got nothing.
I think this might be the motherboard, but I'm not sure.
Any help would be appreciated.

Its sounds like its not even posting. Try reseating everything, and start with the bear minimum.
Motherboard, CPU, 1 stick of Ram, external video only if there is no onboard video.

I reseated the CPU. It's all good now. I should have tried that earlier.
This can be closed now.

How could the cpu get unseated???? It's locked down and the heatsink is locked down...

I have no idea. But I removed it. Put it back. Reapplied thermal grease and it works.
