Haha yeah I did that, the new fan arrived along with a new heatsink, its alot quieter and alot cooler in there now. It stays below 40C. Problem solved. Thanks for the help everyone
Hmm, i'm not sure so i'll just suggest a few things that you have probably already tried. What directory are you using when downloading the zones? Have you checked for any sort of spyware? Is there a firewall which could be causing a problem? (wouldnt explain why the other zones work I dont think) Got any geeky IT buddies in uni that could help? Ask in chat=techhelp. Someone there might know, i'm pretty much a computer idiot so im not sure if what I suggested would help or not.
It is definatly the fan, the fan keeps locking. PC shut down at 82C yesterday, ive temporarily fixed the fan but it wont last long. I have ordered a new one that should arrive sometime this week, hopefully this will solve the problem.
