My cousin and I overclocked a P4 2.4ghz Northwood Core to 3.3ghz quite easily with a Zalman CNPS7000-Cu and tonight we stupidly decided to change the RAM clock from 320 to 400mhz. It of course wouldn't boot and now we're left like sitting ducks. We got it to past the POST screen and it started to boot Windows XP but it continuously froze on us. Would removing the CMOS battery fix the problem? Or what would we have to do to make it work again? What are the possible problems that we may have on our hands? Thanks for all your help and please, help us.
