thanks for the advice so far, peoples.

I disabled the sound on the alts, and THey stopped crashing. However i did get 1-2 crashes on the main computer. I tried disabling sound on the main also. No crashes so far. Seems that maybe the new sound card is causing crashes. I will keep posting.

Does kinda suck though... any idea why my sound card would be causing crash? I even updated the drivers... should I try buying a different sound card?
