So I built a new computer a couple of weeks ago and LOVE it. Then I leave town for a weekend and my roommate uses it while SMOKING CIGARETTES letting the smoke get sucked in by the fans. I had used the computer for weeks without experiencing one single crash. I come home to find a layer of smoke dust/ash covering the fan intakes and get hella mad. Ever since that weekend he used my computer, the pc has been crashing about once an hour or two. No blue screen, just a complete lack of responsiveness and the speakers start emitting very loud static. Could there be dust messing with an internal component? Please help, I'm sooo sad!!
