Need help, I have a blue screen

[DMTron]

So first my computer started to shut off, as if unplugged. Then a blue screen started popping up but restarting fixed it. But now this BSOD pops up every 5 seconds after the start up. It says registry error and stop code # 0x00000051. I went into safe mode and no crashes, also my windows 8 on another HDD works perfectly. System restore does not seem to work because it doesnt even show me any restore points. Downloading anything from the browser does not work in safe mode, and I ran an anti malware program which found some malware but that didn't fix it. Nothing new was installed. Please help, I have alot of things on my Windows 7 and dont want to factory reset it.
