Here is the problem I have been having consistently... I first started off using vista, upgraded to 7 then 8 and the problem still exist. My desktop will work for a few months, then at aorund 3-6 months into it working fine, suddenly it will not boot up. First it would take a few times to boot up, when it does boot, it freezes around 30secs-5 mins after booting. As time progresses, it gets worse... it will take more and more attempts to boot up and eventually it would not boot at all and I reach the black screen of death.
I can confirm it is not a virus as I have wiped the HDD several times before. Multiple virus scans showed nothing at all.
Has anybody got any ideas as why this would happen every 3-6 months? Please help because I can't really afford a new PC .
