[QUOTE="William"]\nThanks Baron. Just two more questions. Should I run the setup disk\nthat came with the mother board? If I do a clean install do I have to\nregister windows xp again and how about the password and will I loose\nall my other programs? Thanks.\nWilliam[/QUOTE]\n\nHi William,\n\nYou can do what is called a "Repair Install" where all your data remains\nintact, but so do any nasties that you may have. You will still have\nto to the authentication simply because you have changed the mainboard.\nM$ consider that it is a new computer. Just tell them the mainboard\nwent faulty and its been replaced. It wont be a problem !\n\nWith a clean install you will still have to authenticate with M$, but\nthat is a trivial matter.\n\nYou can always reinstate your password, so I don't see that as a\nproblem ! As far as your programs are concerned you have the original\ndisks, don't you ! So just re-install them.
