In my opinion, OP has severe hardware issues, most likely a bad motherboard or hard disk, or he's using a frankenbuild/modified windows install disk.
Any one of these things could indeed be a factor.
Raw was reseating the hardware, but to test it is a little harder. I would wait after a clean install to see if everything checks out before going that route, but it doesn't matter. those tests just take a long time. If someone would like to post Ram and gpu testing tools, that is fine. I do not know how to test motherboards and hdds in this situation as I have never encountered any free software for such tests, or I just don't know about such software.
I gave Raw the benefit of the doubt when it comes to hacked installs. I thought about it just once previously as well.
^Raw, if you have a hacked installation, you are wasting our time. If not, then please continue on, and let me know how you are doing.
