Anyone know how I can completely erase my hard drive so I can start my computer over from scatch. It is all screwed up with viruses and hijacking stuff. I have saved all my important stuff on CDs. The problem is I don't have a boot disk or anything like that so I can reload Windows and all the necessary start up stuff. This thing is really acting up now. I have to ctrl+alt+del and open up task manager so I can end process on about 20 things before I can use the computer.
