|"My CPU fan not spinning for a couple of weeks"|
Does that mean you haven't used your computer for a couple of weeks? If not, how is it that your CPU didn't fry without a cooling fan? Could it be that there's some sort of fan controller that adjusts the fan speed based on temperature & you just never noticed it before? Did you check settings in the BIOS?
Why did you put "whatever" for the CPU/RAM? Don't you know or didn't you think it was important?
