Not sure where to jump in here. My problem is a little different. My Windows 10 PC performs perfectly, except that it fails to reboot after a power outage. Instead of starting windows I get a blue screen with the message: "your PC has a problem and must be repaired." All attempts at automatic repair fail. What does work reliably is to launch re-installation of the operating system from the Windows source disk. When I reach the point of choosing the disk drive for installation I terminate the installation, and shut down the computer. Then when I push the power button the computer boots normally. I believe that somewhere during repair attempts I have seen a message that indicates that the rundll32.exe file is either corrupted or missing. My hardware configuration is as follows: Gigabyte GA-Z77M motherboard, Core I7 processor, 8 GB RAM, Crucial 128 GB SSD, 1TB HDD. Operating system and all executable programs are stored on the SSD, most user data stored on the internal HDD or on an external HDD. The SSD has about 50 GB of unused space. A 100 mB partition labeled as drive (L) contains folders labeled "boot", "recovery", "system volume information", and "Temp". This problem is not a killer as I do have a work-around, but it is annoying, and I would like any ideas other users can offer.
