Yeah, the first time I tried overclocking I found what I thought was a good stable speed. After a few hours everything seemed fine so I left it as it was. I woke up the next day and my computer wouldn't turn on. I figured it was because I overclocked it but brought it to a tech place just to be sure, and sure enough I fried the chip. Anyway, I call Intel, they ask me a bunch of questions, whether I overclocked it or not, blablabla. I told them I hadn't and they said they needed proof or they wouldn't send me a new processor. I called the guy up and asked if he would vouch that I hadn't overclocked, he agreed. I had Intel call him, which surprisingly they did. A week later I had a brand new processor.
I'm curious if they ever inspected it and figured out that it had been overclocked though, I never heard back from them or anything.
Point of the story: there's always a way around things, just gotta figure out how to work the system! =D
