Hi ok so my laptop its a Gateway running with vista if that makes a difference. Anyway if i leave it untouched for any period of time it completely freezes and have to push the power button to turn it off. I tried changing my screen saver and whatnot but that didnt help. And i think my computer is running slower. But I dunno. And sometimes my Itunes freezes or when opening a program its slow. I have AVG and ran scans and i have spybot and they both havent come up with any virus's. I dont know anything about computers just that something is wrong please please help. Since i dont know anything about computers if you could please be detailed that would probably be soooo much more helpful. Thanks in advanced.
