I have gotten this twice since a recent change in my windows 7 license however I was getting a lot of problems before. I have ran hdd test and ram test multiple times and none of them have come up bad and I am beginning to think it might be my mother board or my psu, and i don't know how to test either. I was hoping someone here might be able to help me by pointing me in the right direction. As a note I get a sound like my hard-drive is skipping or something but all the test I have run says its good.
