I really cannot point my finger at what is wrong. I re-installed windows on a different hdd I had lying around, and same thing happens on both hdds, I ran memtest 86 and the inbuilt Memory Diagnostics Tool from windows and it says memory is good. So it could be the motherboard or processor ? I have no ideea what to do next, I want to smash the pc with a brick. I have been googling for ages and cannot figure out what is broken.
Update: The motherboard is AM1b-ITX. here's some pictures
