I have recently decided to reboot my Windows 7(64-bit), because of a blue-screen error. However in the middle of running the boot... the service screen appeared and the whole thing just STUCK!!! Now when i restart my windows 7 again, an error would pop out askig me to restart.... So any solution guys??? I would really appreciate it. I have tried booting in safe mode but the error still comes out. i have created a recovery disc beforehand . But how do i use it if the screen won't goes off ..HELLLPP!!
