Error BCcode??? HELP?

[nearlycivilized]

I had just finished installing a game on my computer and when it finished my computer restarted on it's own. And I got and error BCcode error message saying a serious error had occurred. My virus protection is all up to date so I don't think it's a virus. I also haven't installed anything other than a few games in the last few months. I haven't kept up on cleaning out my computer so I know I'm running way low on space. I only have about 13.9 GB of space left which I know is too low. I scanned the game with SpyBot and it came up clean, so I really don't know what the problem could be. Should I just uninstall the game and hope for the best? Does this mean my computer is about to crash?? I'm just terrified of my computer crashing. I haven't backed anything up ever and can't afford to have it crash. I know this is a bit of a learning a lesson kinda thing for me, but any tips or advice would be greatly appreciated.
