Slow running dell

Hello. My Dad has a Dell Dimension 2400 with an intel celeron 2.4 gHz, 256 megs of ram running Windows xp. It is freezing up and stops responding alot, and I can't figure out why. He uses a dialup connection. I will post the hijackthis log file. Please let me know if anything looks screwy. Thanks!
