Ever since I formated my hard drive about two weeks ago, my computer has been having major problems. The main symptom is random shutdown. This happens no matter what i'm doing - booting to winxp, checking out bios settings, booting to a cd. This seems to be a heating problem, however I have plenty of fans, which are all working, and it even happens when my case is open. I can't feel that much extra heat from any component, and I can't smell any burning plastic. My specs: Athlon 64 3000+ 1 gig of ram (2x256 and 1x512) CD-RW DVD-RW ATI Radeon x800 pro 256 mbs K8T Neo mobo (very old bios) 2x80 gig hard drives in 160 gig raid 0 12 gig hard drive Let me know if you need anyother info. Bear in mind i'm having problems even getting into winxp, as it sometimes shuts down before xp is completely booted.
