MSI Starforce 8816 overclocking

[Guest_imported]

Just overclocked my 8816 under win98 using MSI utility. Set the memory speed to 200MHz, applied changes and instantly screen became blurred and system crashed. Windows will boot, but after startup is complete, same blurred screen. However, windows does not always crash. I'm usually able to reboot using keyboard.
Now how the **** do I get those clock settings back to original?? I've tried everything including uninstalling video drivers, but it seems like windows retains clock settings anyways. I know it's not the hardware that retained the settings because I run a dual boot Win2k/98 and win2k runs perfectly.

Any help would be greatly appreciated (of course formatting is NOT an acceptable solution

Thanks!!
