I built my Computer, FX-8350 (with aftermarket cooler), Radeon HD 7870 and 16GB DDR3 1600MHZ and Gigabyte 970A-UD3 MoBo. I am running Windows 7 Ultimate. About 1-3 times a month, it will freeze. It never happens when I am using it, but I will come back to it after being away for a while and the screen is black (I have it set to turn off after a few mins), the numb lock light is on the keyboard and the computer is running, but it won't respond to keyboard or mouse actions. I have to reset to get it to use it. When I do that it will say "Windows didn't shut down properly" during boot, but it never say anything when it gets to windows (like "Windows has had a serious issue.." etc. ) and there is no crash dump file in the minidump folder.
I though maybe it had something to do with it automatically going into sleep mode, but I turned that off and it still did it.
