I have a problem with my computer running slow and freezing up. I am using windows xp and firefox. I open firefox and sometimes i can't even get my homepage to open up. When it opens up i try to go to a site it freezes up for a second and it does this everytime i do something on the internet like scroll down or up, type something or try to go to a site it freezes up. I seen on task manger that svchost.exe using 100% of my computer.
I tried windows uopdate agent 3.0 x86 for windows xp and its says already installed.
I tried windows xp kb927891.exe and it says service pack version is newer than the update you are applying no need to update.

Do you think that is my problem and how do i stop it I know I can't delete it so how do I stop it from using 100% of my computer?
