More help needed

Thanks a lot. But I'm afraid that it's more than I'm capable of. I don't quite know how to do those things mentioned in your msg.

BTW, I guess it's better I spend some money now - better than me totally messing up the system. Do you think the $30 Mem Turbo software (one of those popup ads or the wenxuecity banner offered I'm not sure) can do the cleaning and speeding up and optimizing the system job?

Again, thank you just the same!
