brothers computer...was installing directx 8 and computer locked up. ctrl/alt/del and went into setup. He suggested I reset the Bios to "default". Now there is a constant "WA WA WA WA" on speakers and no other sound. When I open volume control there are 4 green bars on wave balance. Board has MVP3. Can find no conflicts in control panel. This has happened before and he got rid of it by reloading windows...didn't work this time. Running windows 98. It also always goes to the screen on startup of selection for "safe mode, normal, dos, step confirmation". This may be unrelated....
