Had bsod. Mini dump file indicated memory corruption. Subsequent attempts at rebooting resulted in Windows attempting automatic repair unsuccessfully.
Memtest x86 identified one of two 8 GB stick of memory was bad. This was removed and the remaining 8 GB tested good.
The boot behavior of the computer did not change. Srttrail.txt showed
root cause found: boot critical file D:\boot\resources\custom\bootres.dll is corrupt.
And it was unable to repair the file.
I've tried restore points which were unsuccessful. I tried doing a repair reinstall with an ISO image of Windows 10. Apparently, since the image could not confirm that I had a working version of Windows 10, it would not allow that process to occur.
I ran chkdsk /f and sfc scannow.
I examined the folder reference in the error message in what I think is the boot volume by entering the command prompt after the failed recovery. That file does not exist in the referenced folder.
It does exist in C:\boot\resources\ (one folder up).
Any suggestions appreciated.
