I've been working on computers for quite some time, but this has me completely perplexed. Just purchased a new case (NZXT Guardian), new EVGA 650TI vid card, 4 gigs of Corsair PC 6400 (Dual Channel), have two hard drives (500 gig Seagate w/Vista loaded/350 gig WD Caviar w/XP loaded), new 750 watt Corsair gaming psu, new Asus M2N32 SLI Deluxe board (wireless edition) and two new DVD-R/DVD-RW drives (HP drives) and AMD Athlon 6000 cpu. When I hit the start button, everything fires up for about 5-6 secs, and the system shuts off. I've tested the psu and it's fine. The memory works in another computer, and so do the h/d's and optical drives. I keep thinking there's something wrong with the board or chip. I've torn this build down and rebuilt so many times in the past three days my heads spinning. Thought I'd get some fresh perspective on this thing.
