help!! Dell Inspiron 510m, XP service pack 3 i have my friends laptop, it's an old laptop from his works and i have been updating it for him - nothing special just XP service pack updates etc which worked fine. He also asked me to try and remove the old account on it (not yet done that) and set up one in his name. From the normal Users menu it wouldnt let me add a new user as the new name was not part of the domain (ACCESS161). I was looking in the system settings, i may have changed the computer name or selected a prompt under work group (this is off memory, my laptop is vista so cannot verify the window i last remember). What ever i clicked said it would restart the computer (which it didnt). But when i did turn it off, i can no longer log onto Windows. I get the normal windows professional log on screen, the old username appears, but when i type in the password (i know i am typing in the one that previously worked), i get the error message: "The system could not log you on. make sure your user name and domain are correct, then type your password again. Letters in passwords must be typed using the correct case" I know it used to use a domain called ACCESS161, but i cannot get a domain option from the log on screen under the "options>>" button - which from memory i am sure i could get before. Its just blank where you would expect the pulldown menu. I read a few previous posts which mention bios passwords or ..... I haven't a clue which is a bios password or not, so please remember you are answering someone with limited setup knowledge... ...i knew i should have left it alone ! thanks.
