Hi, you say it keeps crashing , is this just random or when you specifically do something? Did you recently build the PC or buy it? You see there could be many variables to your problem but to start with make sure all (and I mean all) your drivers are the very latest release. 2. Check your system temps, are you running too hot? The 6000+ is a 3.00GHz chip so runs pretty warm. 3. RAM, Try running the PC with only one stick of RAM installed at a time. If one of them runs ok and the other one doesn't then there's your problem one stick is buggered. 4. Overclock, have you overclocked the PC? If so you may need to back it off a little until it becomes stable. Hope this helps, let me know how you get on...
