Are all your BIOS settings are what you expect them to be when this happens? Or are they set to defaults?
The PC goes directly to the BIOS without a prompt? I'm not clear if you are stuck in the BIOS on each restart, or does it boot into Windows at some point?
Do you have Windows set to apply updates automatically, or do you install them manually when they are available?
You haven't filled in your system details, really a requirement for getting help in the forum, since it tells us what we are dealing with, and saves everyone time.
