Probably not the most appropriate forum to post a topic like this, but this is the only computer-related forum that I am a member of.

Just recently my computer has begun giving me blue screens randomly. The last downloaded program (that I'm aware of) was PokerStove, a freeware poker odds calculator (from pokerstove.com). I have since uninstalled the program, deleted temporary internet files, and defragmented my harddrives. I'm sure I haven't begun to solve the problem (in fact, I know I haven't, as the problem persists). Does anyone have any suggestions?

I'm in college (= broke), so I'm trying to avoid expensive solutions. Also, I have never encountered this before, so I don't know what I should be doing.

Any help is much appreciated!

Edit: I ran a free scan by RegCure (RegCure.com), which found over 400 "problems" with my "file/path references", among other "problems", even after defragmentation.
