Welp, it finally happened. My computer got so buggy from all the weird junk I installed on it that it blue-screened and refused to come back up. I finally gave up and just restored the entire hard drive back to factory default...fortunately I'd backed up most of my important stuff, but I don't even know how much I lost in the process, a lot of it my old Game Making files.
Blah...oh well. At least my computer is finally running a bit more smoothly.
