College Campus - Sudden Rash of BSOD

Dec 12, 2019

Work on a college campus using Lenovo M-series desktops and over the past week we have suddenly started experiencing a rather large number of PCs (14 or so machines this week) on boot experiencing BSOD. We are not exactly sure what is going on and was hoping to get some tips on directions we should pursue.

Lenovo M-Series Windows 10 Pro version 1803

1. Majority of the issues occur when staff power their PCs on in the morning. A small few have occurred on rebooting their PC after using it for a while.
2. Some of the machines have been fixed by running Startup repair. Other machines are not fixed with this or using any of the other repair options (system restore point, uninstall last update, etc...)
3. Problems only seem to be occurring on the newest machines we have put into service (last year or so). We have not seen any of the older machines having this issue.
4. A few of the machines that have been fixed with Startup Repair have had the error occur again and fixed with another Startup repair.

I have attached some of the log files we have gathered but we are at our wits end. Any direction for troubleshooting would be greatly appreciated.

Here is the important part from the srttrail.txt file:

Root cause found:
Unknown Bugcheck: Bugcheck 7e. Parameters = 0xffffffffc0000005, 0xfffff8071574c05a, 0xffffe20f97bd5108, 0xffffe20f97bd4950.

Repair action: System files integrity check and repair
Result: Failed. Error code = 0x57
Time taken = 922 ms

Thank You

Did your system admin run updates on all units concurrently?, do you not have backups?. Has your system admin done a virus scan?. :)

Several known WinPE systems that can fix a boot issue, depending on what caused the BSOD.
since Windows has Blue screen, Black Screen and Green Screen would be nice to know exactly which.
suggest Boot that PC to WinPE obtain the dmp and view it so as to find... if it is a BCD issue that is more easy to fix.
but still you need (IMO) a WinPE boot option.
