Yea, my hard drive is failing. Good thing my new is shipping Monday!!! Every time I try to run a disk cleanup or defrag my computer restarts. You might want to check your disks for errors by the way.
i think it is the power supply, i was listening closely, when i put the power cord in, it started to make this slight buzzing noise, it never did that before.
Well, it ain't the power supply, i just swapped it with my sister's, didn't work, i think it's safe to say that it is dead now, oh well, great excuse to buy a new cpu and mobo!
