Computer Problems

My computer is on the fritz now. It was working really well last night but this morning it was lagging like crazy. I tried working on it for about 4 hours (I know...). AVG is still running and I'm trying to see if any other sorts of evil things are wrong with it. I'm actually in the dorm's computer lab, which reminds me of computer labs in Argentina, from the early 1990's. It's been a while since I've seen computers that only take floppies. :) I'm going to go ahead and reformat my computer sometime soon to see if that helps. It might just be that the computer is finally falling apart. Maybe God is trying to tell me something (other than to buy a Mac)?
