I am running a 2.26 p4 (533) on an abit BD7-II board. I am currently running windows xp professional. The problem is with my on board sound card. When i had windows 2k installed everything was golden. Under XP however sound comes and goes which is really annoying. I have tried all the different drivers out there but it does the same thing. At this point in time i dont care if it has support for surround speakers because im only using headphones. But if anyone knows and drivers or BIOS update that would fix this please let me know thanks. BTW the sound card is an Avance AC 97 (i think) ICH5 chipset if i remeber correctly
