So today I cleaned out my dusty tower and desk (unplugged everything and plugged everything back to the way it was. I do this about every 4-6 months and never have issues). Turned my PC on and no sound was coming through my speakers. The bar in the bottom right, the volume mixer, showed the green bar going up and down indicating that there was sound. Tried the old fashioned unplug and replug method but to no avail. I uninstalled and reinstalled the Realtek drivers, but that didn't work either. I use a USB headset every now and then and that seems to work, although I don't think it correlates to the motherboard (or does it?). Regardless, I've never had problems like this with my OS or motherboard at all. Both are around four years old.
I'm not sure if its a hardware or software issue at this point. Any help would be appreciated. I've been reading threads similar to my issue and none of them have a final solution. People suggest reinstalling Windows but of course that would SUCK. But I guess it's a final option I'd have to consider.
