I recently upgraded my pc. It was an AMD and it randomly crashed due to what I belief was overheating, so I took off the side panel and put a mini fan on the cpu and it worked fine, except on real hot days. So I upgraded my CPU and mobo, but the problem is still happening. The computer randomly crashes at any given time, it just turns off, and reboots automatically. Windows then tells me that it has recovered from a serious error. Any help would be appreciated.
