Bwoods,
I don't really have another way to test everything. We've already been over the dust thing. I cleaned everything out thoroughly and checked all of my components. The problem has actually gotten worse since. The entire system freezes up while loading up the startup programs. Nothing responds, can't turn on caps lock or anything, complete graphical freeze, and only able to restart by hard restarting.
I am starting to wonder if this is a bigger problem than the GPU. Why else would everything else stop working when the card froze up?
