I had everything set up, ABit KN9 SLI board, AMD x2 64 +3800, HP DVD-RW, WD 160gig SATA HD, Corsair 2gig 800mhz DDR2 ram, 350w Raidmax PS, and an XFX 7600GT. It ran perfectly, played DVD's, ran windows fine, then sunday hit. Now my USB keyboard and mouse will flicker on and off, and I get a soft lock anytime I try to boot a game. Any suggestions on things to check?
