High and thanks in advance for any help you can give me.

I recently experienced a general slowing down of my computer processing speed when opening simple programs like firefox or word. Also several programs have quit working such as MS Money 2006, Windows Media Player 11 and a couple of my EA Lord of the Rings games. Money and WMP start but unexpectedly close out. The games start but then close out and a "Error 103 " message pops up. In addition, I don't know whether this is applicable but my optical mouse has begun acting very erratic. I will post my Hijackthis log and thank you again for your assistance.
