i was recently deleting suspicious registry keys when i was infected with a serious virus, unfortunately this was in the folder "microsoft" and i deleted something with lowercase letters without official meaning and without a capital letter starting the name and now my system starts and then just blanks without an error screen, this also happens in safe mode, when it starts up windows with the logo, straight after in all cases, it blanks and i cant get anywhere, it just goes black. I desperately need some files off the hard drive for a presentation for tommorow which is very important, i need to restore the system somehow!
Please help!
Thanks
Max
