1. Forgot to mention about Memtest. After I changed the RAM and ran Memtest, it ran for 13 hours and had no errors.

2. Yes I uninstalled AVG antiSPYWARE but there is still AVG 7.5 Free which is my antivirus software. There is also a Spybot S&D and a Adaware SE but that doesnt load on startup, only when I click on it. I dont think there are any other ones.

3. Yes I updated my chipset driver with that site in a few posts above.

I'm not exactly sure about my power supply since I havent tampered with it to my knowledge. There is nothing software or hardware that has changed recently. I only removed the lid to clean out the debris and dust but I doubt that I may have loosened some hardware or another somehow by doing that.

Power supplies have been to known to either fail to supply the needed voltage and a faulty psu can cause all kinds of problems.

I suggest disabling AVG 7.5 Free and see what happens.
