What is the error that you have. It may be able to be fixed. It is much easier to do that then set the laptop to boot from the CDrom in the BIOS, then wipe, reformat, reinstall windows and then go looking for all the drivers you need. You may have problems finding the drivers also. I take it you cannot do a restore, or get into safe mode to do any repairs. True? There are password programs that work off CD's if you can look for them. Can You log on to the computer via safe mode, use the administrator username and a blank password to log on to the computer? If not you make have to go thru the reinstall ordeal.
