I bought a new computer with 8.1, for use by my secretary. I installed all the updates (finding a way to install them immediately was difficult). Then I loaded the software we use. Then I loaded our confidential data for hundreds of clients.
Three weeks later, it started giving error messages and was spontaneously rebooting. I tried every option offered by Windows 8.1 with no success. The messages I was receiving made it impossible for me to determine if I had a software problem or a hardware problem.
I decided to at least try to examine and repair the hard drive. But when I tried to run SpinRite, the secure boot would not allow it.
The problem might have an easy fix, but I have no way of knowing (I also tried resetting the memory sticks). So I now have a nearly new computer that I am going to have to return to the manufacturer. Before I do that, I have to clean all of my client data off the hard drive. I cannot do that because the computer will not run for more than a couple of minutes without rebooting (the fan is working).
Apparently I will have to remove the hard drive, connect it to another machine, wipe the data, put it back in the defective machine and hope that I have not voided the warranty. Secure boot sounds like a great idea. It would be more helpful if Microsoft would trust its customers enough to give them a choice. I have spent hours of time on this problem, after spending hours learning to use 8.1.
My other plan is to remove the hard drive, trash the computer, and go back to a machine with Windows 7. I understand it may be less secure, but it is a lot better than XP. I cannot afford the time and trouble it is costing me for 8.1. I need to work and may have to take my chances with my firewalls and security software.
Any thoughts or ideas would be appreciated.
