can i take my computer into a shop and get it like....overhauled? for example;i have almost zero disk space left, and more spyware than i can deal with. so basically, it is sooo slow. i cant even get into the "add/delete prgrams" deal, cuz it will just do nothing. but, i have hours and hours and hours of video on it. (i have one tape for my camera, and i've taped over most of it, smart eh?) so, could they clean it up, delete everything except my video files, my video program, and all the necessary things?
