I have been having problems with my ACER notebook booting for a while. It first started to shut down automatically at various times, leaving me unable to successfully reboot for around ten minutes after automatic shut down. When computer did eventually reboot i encountered an option screen with the various booting options. After this happened for a while i was advised to use the system recovery disks. Halfway through a full recovery the computer shut down automatically. I am now left with a completely wiped hard drive, with no operating system and it still will not allow reinstall windows. I would be very grateful if someone could help me with my problems!! I am suspicious that i may have a boot sector virus. I have no idea what to do now... is there any hope of saving my computer?
