ok like the title says..my computer randomly restarts. I i have run norton virus scan, spybot search and destroy, ad-aware, memtest86 and also switched out video cards and nothing has helped. Im running xp with sp2. a few times it restarted i got an vpu recovery message from my video card..so i thought that was the problem...but it wasnt. i installed a new card and no more vpu recovery errors..but my pc still restarts. i have all my drivers up to date. i just cant figure out what is causing it to restart all the time...HELP!
