Boot in safe mode and run a bunch of antivirus programs, or reinstall Windows.

 

Put in your Vista disk, reboot the computer, press the F key that lets you boot from the CD and choose the repair console. Then, perform a repair operation or system restore.

does this mean iv lost all my info ?

 

hi iv tried to put the disc in and press the f key but still nothing you can hear the disc start to spin then it stops tried rebooting it in all modes but still blank screen ant more help please

 

No it doesnt mean you've lost the info. Prob a virus or something. Try taking the HD out and plugging it into a desktop machine as a secondary hard drive and then running a scan on it or something.
