i caught a virus bought a week ago. it got so bad i had to delete the whole partition and reinstall windows xp. now my pc is going extremely slow. all my memory is there and the virus protector doesn’t see any viruses and the registry is fine. so why is it going so slow still and how can i speed it up? im on a low budget

I have two internal hard drives and am adding an external hard drive. If I primarily utilize this external drive which is enormous (1T), will it help speed up my processor? I am considering transferring all of my large files such as videos, pictures, and music on this 1T drive and using the two internal drives for ‘regular computer processing’ and small files, like word documents.
