Well I recently upgraded from a 512mb pdp +xbl stick to 2 1gb ocz pc-4000 gold sticks. I changed out the sticks, reloaded the cmos, hit f1 to boot normally. Now if I try to shut down and restart, the computer hangs up the black screen (the one right before the windows screen) then it beeps once, and goes back to the nforce 4 lan party screen. I think this is a really strange problem, any ideas? Thank you all !
