One thing that strikes me as odd is that your experience is quite different from most other's. May I ask what OS you are running? How long is it since you installed Windows? Have you checked the event logs for errors? Are you running an up-to-date virus killer? Anti-spyware? Have you had a virus attack in the past? Are there any weird processes running that eats up the CPU? Etc.

Thanks!
