Hey guys, I finished my build today. CPU: i7-3770k GPU: XFX HD 7970 MOBO: Asus P67 Sabertooth PSU: Corsair HX750W As soon as I had it finished I hooked up all the outside parts and nervously turned it on... The fan turned on for about 2 seconds and then it switched off for about 4 and came on again and this repeats forever. I've double checked all the wiring, tried running it with one stick of RAM, with and without the GPU, took off the fan. When I turn it on the CPU led on the MOBO lights up, from what I've read online this seems to be a pretty frequent problem with this motherboard. I'm just wondering are there any definitive solutions to the problem? Because as it is, I don't know if I can even afford a new MOBO after all I spent on this build.
