I had this problem in the past few months and i can't seem to find out what the is the problem.2 Days ago i reformat my PC because i thought it might fix it , but sadly it didn't.My PC just freezes randomly, i can't do anything except for pressing the reboot button. It always happens 3 times or so in a day.

Here are my PC specs:
OS: Windows 7 Home Premium 64-Bit
CPU: Intel(R) Core(TM) i7-3820 CPU @ 3.60GHz (8CPUs), ~3.6GHz
RAM:Corsair Vengeance 16GB
Video Card: AMD Radeon HD 6900 Series

My video card is 2 weeks old, i recently check the memory test and it said no errors are found.

Really frustrated right now -_-
