First off this will be my 3rd post, i have had no replys to my others hence the title. right, I HAVE NO SOUND. i was running on vista all was fine then i lost my sound saying no driver installed error 10, i tryed everythink the forums were saying so i reinstalled windows xp, now its saying i have sound but i dont. i dont even hear windows sounds. i have updates my motherboard updated drivers the volume is fine, checked the bios etc etc i have done everythink, one thing i did notice is when i update my soundcard driver "Realtek AC97 WDW Combo" << i think its that. once again my pc loses my soundcard saying error 10, so i roll back and i get my mixer back and everythink else saying i have sound but i have nothing coming out, i have tryed headfones and speakers that work fine on other equipment. its driving me mad, i have done everything formatted my computer and reinstalled everythink from fresh am running out of options i have emailed realtek it took them 4 days to get back to me and alls they said was what number is your soundcard which i replyed 580 i think it was now 12 days later am still waiting for there reply, Is there any Experienced helpers out there!
