windows wont boot after oc

[chinkgai]

i get this message when i overclock my palomino 1700+ to 1600 mhz (133x12):

windows 2000 could not start because the following file is missing or corrupt:

<windows 2000 root>\system32\ntoskrnl.exe

please re-install a copy of the above file.

it boots fine when i have it set at 1533 (133x11.5)

i have 1 gig of pc2100 ram and an abit nf7-s mobo. the cpu does the same thing on my friends computer and he has a really good fan thats better than mine. any help would be nice. thanks.

well I would say it's because your CPU is unstable with the overclock. Have you tried giving it some more voltage to see if it alleviates the problem? Lets see how that works.

This is a very often problem, corruption of windows after unstable overclock. You always need to have a backup else you will be reinstalling often.
One good method to avoid this is to test boot with Memtest86 which will tell you if memory can handle overclock, if not then do not boot into Windows because you might have a corruption easily.

corey, i tried upping the voltage and that doesnt help

joe, thanks for ur response and suggestion, so you think its my ram thats not able to handle the overclock? should i get new ram? oh and about the corruption, after i get that message, i just restart and go into bios and change it back to the regular clock speeds and the file is no longer "corrupt". thanks again.
