I am trying to get a computer that has been seldom used over the past year back running smoothly, mainly to do my taxes. The only problem I keep having is that anywhere from 5 to 15 minutes after startup it will freeze and I will have to shut down and re-boot to get going again. After it does this once or twice, it will be fine for quite a while. It is aggrivating because you don't know when it is going to freeze up, so it is kind of hard to work on something of importance on it because it may freeze and cause you to lose your work.

I updated my version of HijackThis, and it said I have the latest version 1.99.1. I would greatly appreciate someone to take a look at this recent log and tell me if there is anything I need to get rid of.
