i want to revert back to windows xp pro from vista home basic . vista home basic is my original operating system . i have tried a bunch of different things and nothing so far has worked . when i put in the xp disk it goes to a blue screen and says to prevent damage to your system the installation will not continue . it also says if a driver is in question try starting in safe mode or try switching video adapters and to disable shadowing and caching . i don't know what driver would be in question and i don't know how to switch video adapters . i tried disabling shadowing and caching and that didn't work . i also tried using a program that completely wipes your hard drive clean and tried installing xp fresh and that didn't work either . any suggestions please ? all comments are welecomed . thanks !!!
