I'm building my first custom built PC and it's been one headache after the other. I had it up, I had it running, everything was working and windows installed. Then I put in the GPU and now the CPU fan does not work. It tries to (it sputters, tries to spin but stops) and in the BIOS menu you can watch it going "1165" RPM or so and then "N/A" and back again. I shut it off before the temp climbed to dangerous levels. I then removed the GPU and used the onboard graphics and the problem ceased. Heres the set up of the parts in question.
ASRock B75M Intel Mobo running UEFI BIOS
Intel i3 2120
Corsair 430W Builders series 80+ certified
Coolermaster elite 430 Case
Windows 7 Ultimate
Any idea? The PSU shouldn't be having problems supporting the GPU and CPU. I've run that GPU on a far smaller PSU with no issues. As it is I can only run the desktop without the GPU and like that, I can't do what I wanted with it. And overall I wouldn't even want to run it if the CPU's fan might be having issue. What do you think is the problem? The MOBO, the PSU, the CPU? Just need to know what needs to be sent back.
