Ram trouble after installing Office Service Pack 3

I never had trouble with my PC until after I installed this Service Pack 3. It seems like it is a RAM problem where everything is slow, especially my Internet Explorer 6. :cry This is so frustrating but this is my work PC (work for a very small company) and the IT guy is very rarely here and I would rather not wait for him to come to figure it out. Uninstalling is not an option yet. Has anyone else had this issue or any ideas on how I can correct it? Thanks!

 

There does seem to be a few problems with sp3- if you want to work as before , until your IT expert comes back, then go to 'Add or Remove Programs' from Control Panel, tick the 'Show Updates' box, then go to to the bottom of the listi, and select 'Windows XP Service Pack 3' and click the 'Remove' button.

Then reboot, and the machine should return to its pre-SP3 state.
