Thanks for the letting me know that! I build the whole PC myself at the time, the PSU I'm using is a Super Flower 500W wich was an expensive and recommended PSU back then. The reason I never upgraded my hardware is because I am a student with a low budget and mainly use my PC for PHP programming, so never really felt the need to spend my bucks on an upgrade since my p4 3ghz did the job well. Maybe I will now if I know for sure it's my hardware that's failing, will try to install Win7 clean as a final attempt tomorrow (never been off xp). Yet again I'll kep you posted!
