I was having so many problems with my computer, powering down w/o prompting, slow signing to the internet ect. I took my machine to a tech who told me my macine was so infested with virus that in order to save the machine he would have to Nuke The Hard Drive . I did not ask what it ment I just said let me think on it. I trust your knowlwdge and opion so tell me just what does te work NUKE mean?
