Please help.I am running xp home on an e machine comp with a IM845gl motherboard.I am relitivly new to computing and tried to help a friend with a sound problem over the phone.I went into volume control and clicked a few check boxes and while doing this i got a loud(ish) click from my speekers.I then lost all sound.Have I blown my on board sound card?Would buying a new sound card cure this or what????? Or can I rescue my on board sound card???? As I have said,I am new to this so any help would be greatfull,keep it simple guys.Thanks.mickyl.
