This is probably my situation. I say probably since it is so random. I replaced by RAM once with new, and the problem seemed to go away. To confirm it really was the RAM I plugged it in together with the new RAM but it worked so it confused me. Later (a couple of months) it began again and I was suspecting the PSU. But just because I could, I removed the old RAM again and there has been no problems since. I can't tell if I'm just in the lucky period, or if it actually is the RAM, but I'm going to see how long this lasts me.

But it is soon time to get a new PC (or most of the inner content anyway) because I've noticed my ethernet plug is broken on the motherboard and it can never be good to have broken stuff on the motherboard and not act on it with replacements.
