Freezing problem not fixed.

[Dark Nova]

Ok my computer still freezes, i have no clue on what to do. its not the p2p programs because it freezes even without it open(other threat). its not the ram. my only guess is that it could be either a program or the temprature of the room. im going to try to change room, but how can i know if its a program.
I left it at PcCyber they said my pc ran for 48hours without freezing, working with a heavy duty program. now that its back home, my pc freezes every 1/2 an hour. the only thing they did'nt connect is the internet.

Could it be MSN or Skype that is causing this trouble? could it be the internet?
-i also check for virus and spyware every day so there should'nt be any on it

plz help, i have no clue what to do next

I'll assume PcCyber only took your PC box and used their own keyboard and mouse, in which case it could be one of those devices, or secondly yes it could be something from the internet. If you run task manager you can see what all is running and possibly hogging up resources...

ive never hears that the mouse or keyboard could be a problem. but if it was, would it still work for 1/2 hour then freeze? usally my pc freeze when im not doing anything. it froze twice today only running bittornado, and once when there was nothing happening.
thx for the reply.
