I do not have the original IOS disk, otherwise I'd have reformatted already. Sometimes, it doesn't even get as far as that, freezing at the Windows 7 start-up logo screen. It usually loads the background and the icons for a split second, but then freezes. After a couple of more reboots, it now just freezes a few seconds after start-up. I kept trying, persistence overwhelming me. I loaded Firefox to try and figure out what the hell was going on. Once more, it occurred and I figured I'd just stop playing all together. The same thing occurred again and I repeated the process. It worked, booted up normally and I went back to it. I figured I'd just shut it down by holding the power button. I was playing a game (League of Legends) and suddenly it froze on me, with the background sound looping.
I've never experienced this issue up until today.
