I set my overclock options to 10% and lowered my memory so that it is at 200mhz.After i have saved the setting my computer does not boot up, but instead i get a black screen.I have tried just 8% overclock and my pc booted but it did not even work.It was still running at 2200mhz.Any help would be appreciated.

here are my computer specs

RAM: 1gb corsair (pc3200)DDR dual channel
Motherboard: asus a8n5x nforce4

Sound Card: audigy 2 zs
PSU: 450

Did you lock the PCI bus before you rebooted? That could cause it not to boot up.

There should be a setting in the BIOS that says something like PCI bus. You will want to change it from AUTO to 66/33mhz. Look through your BIOS and you should be able to find the PCI bus setting.

What PSU is it? All it says is 450. List the 12V rail's amps. They will be listed on the side of the PSU. Also, what were your idle and load temps before you started OCing? Could it be getting too hot? Another thing is, run memtest86 on your RAM and make sure you don't get any errors. Check those out. Bump your post later in the morning if you don't hear back. I'm going to bed. /biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' />
