I do. It is a pretty decent one, 9 years old. Hard drive freezes every few hours or so though. I was gonna have Tekkev tune it up for me before his mom died. Haven't heard from him lately. It works great most of the time, and when it freezes you just have to turn it off and back on again. I am upgrading to a newer one soon so this one will have to go.
Sounds like a heat issue. crack it open, and clean the fans and such. If thats not the case, probably just gotta regrease the CPU fan, assuming there is one.
