Fixed my computer. Apparently, the problem was a massive collection of dust inside the computer. Got that crap all cleaned out, and my computer can actually DO THINGS NOW. Feels nice to know it doesn't overheat anymore, but I feel really stupid that I went nearly a year dealing with BSODs out the wing wong, having a massive fan blowing in my room all day, and keeping my window open , even while it was snowing, only to find out that freaking DUST was causing it.
I'll probably be making a lot more stuff now. That is, if I can manage to pull myself away from IIDX.
