No signal from any GPU. Tags: Motherboards GPUs Last response: February 2, 2012 2:18 PM in Motherboards Share imarex February 1, 2012 6:52:05 PM Hello. 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.
