hello everyone, I have problems with my computer, when I save a large item it freezes. (large items noramly take 3+ hours to save. Have been doing alot of video editing recently and when it comes it save the overall work (render it), the whole computer freezes, managed to copy the file though the home network and do it on my bro's pc, but I can't save to dvd as it's doing the same. Thought it could be power supply, or processor over heating but if i shut down and restart it, it still has the same problems but it will freeze in a different point, getting to be a very annoying problem. Can't remember exactly what the spec is, if anyone can help would be really good.
