Upgraded build, No video signal, cpu fan doesn't spin Tags: Homebuilt CPUs Systems Last response: January 24, 2013 1:27 AM in Systems Share BoDidely January 23, 2013 11:35:09 PM Hello, Today I upgraded my PC with a new CPU, aftermarket heatsink and a new GPU. When I try to boot, lights come on on all the components and the case fans spin. I also hear what I think is the harddrive booting up. Unfortunately, I have two problems. 1. No video signal. I tried swapping back in my old GPU (HD 6790) that was working yesterday and still no signal. 2. The new fan for the CPU spins for a couple of seconds and then stops. Does anyone have any ideas for me? The CPU fan is plugged in. The case has no speaker so I can't listen for the BIOS post.
