Dear All,
here's how the blackout came. the operating system is vista then that system was attacked by a virus and I decided to reinstall XP3 and replace it with 3. In the beginning the system did not recognize the hard disk after boot. black screen started to date and despite everything. the disappeared from the screen has been gradual. not a screen problem and the machine boots up fine.
tell me what I can do
Your Sincerely
