Hello, i have an 04 compaq desk top with just the basics that came preinstalled. my machine is running crazy! slow even after defraging, do a clean up and removing files/programs that i never use. will deleting compressed files (8,698,862 kb)help? Also, when my husband is online and he clicks a link thru a search engine, the link will not load and after "thinking" about the going to the address it reverts back to the initial search. How do i fix that?
