It's the CPU fan. They're easily replaceable, but the computer's under warranty so I've probably got to send it back to the shop to get it fixed. So as of right now I'm going to be posting from my laptop, on an awful keyboard that keeps missing keystrokes. On the positive side I'm going to use this as a reason to get some upgrades on my system. New graphics card and more RAM, Hooo~ Anyone else ever have computer problems? How long did it take to fix?
