Welcome to the site Kareem

Kareem are you saying that Windows Vista and Windows 7 gives you a black screen at startup?

Are you dual booting both Operating Systems?
If so you maybe able to use the Windows DVD and repair the boot files.

Are you installing Windows Vista as well as Windows 7 to find that neither install will boot?
If so you may try setting your bios to default setting.

thank you clifford
no i'm not dual booting i have only the WIN7 now, this problem appear to me when i reboot it only and i should turn it off (shut down) and turn it on again to work exactly...
