Hello people, Today I needed to post this thread as long as I'm facing a serious problem with my Operating System.I had Windows Vista but before Vista I had Windows XP.With XP I didn't have any problem playing games such as GTA San Andreas and Sims 3.So..one day I decided to upgrade Windows XP to Windows Vista.Everything went smoothly but the only problem was that when I went to the welcome center and I checked my drivers in the System Devices,the display driver from ATI Graphics changed to VGA Standar Graphics Adapter.The problem was that I couldn't even open Windows Movie Maker!So,the only solution for me was to downgrade Windows Vista to Windows XP again...(I know it's kinda complicated)...So,I was doing the setup to install XP again..In the setup,while the files were getting copied sometimes it was saying me that some files can't get copied.I skipped those files until the setup ended.( Go to P.2)
