I have a Windows 7 based pc. And I had seen that my PC freeze for no reason. It occur on boot or sometime when I play game or when I am working. It is very common that the pc freeze when I turn it on for sometime. I checked the RAM and I had tested it with Memtest. But it is not able to find any error. So that is fine. Then I ran OCCT and tried to test my pc for performance. But I did not find anything wrong in that. So can anyone tell what all things can be the cause of freezing. I am not able to play games properly.
