also tried new cpu E2160 intel dual core 1.8 gig tried this on both boards, tried different cpu's, different video cards,, pci sound card instead of onboard, tried different ram, new power supply 400w, tried new motherboard, tried latest drivers, bios, tried running only cpu fan and no power on lighting, I do want to ask for opinions on the HDD it is a new 250 gig sata HDD and I have had no failures at all on an instal so could this still be under suspicion, I expect that if it was going to fail it would have done on one of the multiple reinstals.
