I recently purchased an axp 2500+ and recieved it today. While i left my computer running for around an hour, it crashed and the screen said windows just recovered from a serious error. i'm in windows, though i haven't reactivated windows yet like it's telling me to do. my cpu voltage is at 1.71v, and i can't find anywhere in my f3 bios to change the cpu voltage in a sequence like (1.6, 1.65, 1.7, 1.75, 1.8 etc.). my motherboard is a gigabyte ga-7n400 pro 2. does anyone know where in the bios i can do this?? i'm thinking it's too hot, that's why it crashed... and i haven't overclocked or anything yet. thanks for the replies guys.
