Computer stopped working.

My blog has been laying dormant for the last few days because I have been having serious computer issues. Those culminated this evening in my poor desktop computer crashing on me. The thing just sort of gave up and stopped working. It turns on, but no one seems to be home - it don't send the information to the monitor. I'm not sure what's going on, but it has been acting up for a long time with assorted troubles, so might be time to start looking really sweetly toward Santa Claus and hinting for a new computer.
