P4b266 onboard sound hangs w/ oc'ed 1.6a

Hello, I'm new to the forums and I have successfully overclocked a P4 1.6a to 2.4ghz using a P4B266. The system is very stable but only if the on-board sound is disabled (using the bios setting). If the onboard sound is enabled, the system hangs. Can anyone help on this? Thanks!

fixed problem

Fixed the problem. After some research on win2k and ACPI, I disabled the win2k ACPI by installing 'Standard PC' as my driver for the 'computer' device (control panel->system->hardware->device manager). cool! BTW, doing this also enabled the USB device drivers to be loaded! P4b266 rocks!

Nice tip for OC kasmara, but I´m not sure if it tells Me any good about the quality of this board?
