We recently bought a new computer and have put our old one in our childs room. The computer is dreadfully slow, how can we remedy it. It is an HP Pavillion, we had replaced the hard drive after a crash. It has WinMe on it along with tons of programs. We want to erase the hard drive and install only what we still use, if we uninstall WinMe will that erase the hard drive so we can start from scratch?
