I'm having a curious problem.
I have a homebrew machine using an MSI mother board and gpu, I5 processor, 16 gigs of ram, and Win 7 home premium.
I started out with a problem in a Seagate USB hard drive. It disappeared from windows explorer. A little experimentation revealed that the problem was it wouldn't turn on if I either rebooted the machine or turned it off and back on. The only way it will work is if I turn off the machine, power down, including the power to the disk drive, and turn it back on. Then, everything is fine.
While searching the device manager, I found something curious—there are two entries labelled Microsoft Windows Management Interface for ACPI. Both have the yellow triangle. Both show this error message: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19).
I could use some assistance here.
Could this be the cause of the usb hard drive problem? (It works on another machine using Win 10.)
What do I do about this?
It seems to imply that the registry needs tinkering. While I have done that before, I know that it requires absolute precision, and I'm not certain what needs to be changed and how.
Any assistance would be appreciated.
