Hey guys. So my Windows 8.1 install is really annoying me. i have already installed windows again to try and fix my issue but no luck. Randomly my computer will freeze. The HDD led will go off and i have no disk activity. the only thing i can do is move my pointer on the screen and the screen is the same as when the HDD indicator turned off. It will ever stay like this and require a hard reset or it will stay like this for 3 or 4 minutes and then be fine. i have ran memtest86 and have no errors and i have ran OCCt with no errors for 2 hours. I dont know whats causing it. help!
