Well, we know the RAM works, the graphics card works and the hard drives are running well. I really do not think that another installation of Windows will help and I think that the only option is the motherboard. It's fairly old and it would explain the issues with the memory - especially as my PC always used to overheat before I bought new fans and a heatsink. Perhaps it's fried.
Would you agree that if the problem persists it might be worth getting a new motherboard as there doesn't seem to be any other hardware issues?
