Just spent the last 4 hrs trying to get a Compaq desktop (sorry I don't remember the model info) up and running again. It belongs to one of the other guys who lives here at the Open Door Mission with me. He's an older gent. He had XP home on it and a few months ago did an upgrade to Vista Premium. The unit ran ok for several months until Monday. He claimed that stating Monday when he turned on the unit, The Vista splash page would come up, followed by the do you want to install Vista. I went down today and saw for myself that, that was what was happening. The first page asks what country, and language you want. Made sure everything was set right there before clicking next. The next page is the *Authentication*<http://www.google.com/search?hl=en&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=Authtication&spell=1> page. His code is 5 groups of 5 numbers and letters. After putting them in and making sure I had it right, I clicked next. It came back to the authentication page, and this time there was a yellow triangle on it saying that you need to authenticate. I next tried to boot from the upgrade cd he has. No go. It showed it was loading the files then would go the country page, authentication page and stop. I next tried to boot into safe mode. You could see the screen resolution change, but when it came up it was at the install page, country etc. Clicked to close that and the screen went black with the words safe mode in all 4 corners. No icons nothing else showed. I next tried the F11 system restore. you would get a flash of a screen that looked like a dual boot screen, I mean if you blinked you missed it. Then back to the install page. All these were tried more than once. Next we ran PC Doctor disk that came with it. It said everything was ok. He does not have an Internet Connection. Does not want one. He has not installed any new programs in a while, he claims. So a virus is not likely. I can't get into it toot to run one of my AV's. To me it sounds like the code has been used 1 or more to many times. My next move would be to take another hard drive ( the one he has is SATA, but i don't believe the extra one from my laptop would work), Install it leaving the one that's there without the IDE cable. To my way of thinking i should be able to boot to the new HD. then plug in the old hard drive. I think that by doing this I should be able to get into the My Computer area and maybe figure out what's going on. At worse case I should be able to drag and drop the files and programs he wants to save to my external, then do a format on it to wipe it clean, do a clean install and put the stuff back on it. Anybody have any ideas on weather this will work or not, or perhaps give me some ideas on what to try next. I do have 3 sets of rescue disks. 2 for Acer and 1 for HP. the Acers are Vista and the HP is XP MCE, But I really don't want to put them on there, just got this little voice telling me no no. Damn I can get long winded.
