Hello, I just built a new pc from amazon and it worked very good for the first couple of weeks, but today, while I was playing a game it just crashed and when I tried to start it again it went on for half a second, turned itself off and after another second it did the same thing again and again and eventually I had to turn it off through the PSU because it kept doing like that.
I was thinking that it could be the PSU, the Motherboard or the graphics card but as it is the first pc I built, I can`t know for sure.
The parts are:
Motherboard: P9X79 PRO
CPU: Intel core i7 3820
GPU: Sapphire vapor-x HD 7970 ghz edition
PSU: Corsair 750w
Memory: corsair vengeance 4x4gb
1) The PSU fan does not spin (although I am not quite sure it should)
2) All the case fans and the CPU fans spin, with the exception of the exhaust fan
3) There is a red light coming from a LED on the motherboard: CPU_LED
4) The case lights turn on, but they turn off shortly again like the rest
Hope this might help
Thank you in advance for any advice you can give me.
