PC Freezes Within Seconds After Boot When Not In Safe Mode?

I got a BSOD yesterday which was most likely from overheating and now 30-60 seconds after I boot it normally, it freezes yet my mouse still moves. Ten second later, all the screen shows is my background. I've tried system restore, then I went it BIOS and ran a test on the system memory which passed, scanned for malware and spyware, used both CCleaner and IObit Advance SystemCare to clean up registry and junk files, and then defragmented the hard drive expecting that might do something and it still freezes.Edit: I've been looking at the start ups and don't see anything that suspicious.[CODE]
