I have a 6 year-old Acer laptop that has crashed. Windows will not start and I either get a blue screen or a prompt to restore the system. Restore does not work. I am able to boot from the DVD drive and tried to restore from a set of restore discs I had made a long time ago. The machine accepts all 3 discs of the set but then freezes at 0% progress on actual install. Before I buy PC-Doctor, I wanted to know if it's possible to use it to boot up my machine and then diagnose what the issue is (guessing bad hard drive but not 100% sure).
