ok my computer it almost new with a new mb, vid, processor, and psu. Although it keeps rebooting if i go past the bios screen. Ive been looking inside it and i noticed for some weird reason the main cable has 23 pins, seems like a whole wire is missing cause its just a hole there. That might be why its doing this, not totally sure yet. The psu is an antec truepower 430 so i would be surprised to see a defect on one of theirs.
