If i'm on for maybe 20 minutes, time varies, sounds are all normal and fine then I hear this strange crackeling sound, then everything is fine for about 30 to 40 seconds then squealing, popping, grinding, along with several others sounds starts. It tends to be Rythemic at any rate LOL.
kinda squeal-grind-pop and repeat for maybe 1/2 a sec for maybe 5 sec then it changes to some other combination and some times it jussst a high pitched squeal that goes on and on then stops to be replaced by somethin else.
Once it starts won't stop until I get out of AH then it's fine.
Oh and Disco after Disco after Disco

Have onboard sound and a SB PCI512 with latest driver I could find from SB people. Onboard was disabled but re-enabled last nite and gonna try it in AH today and see how it does.
