Your crash dumps are not showing any finite probable cause. In such a situation, it is better to enable Driver Verifier to monitor the drivers.Code:BugCheck 50, {fffff80040f9e3b0, 1, fffff80000b9a1aa, 5} *** WARNING: Unable to verify timestamp for ntoskrnl.exe *** ERROR: Module load completed but symbols could not be loaded for ntoskrnl.exe Could not read faulting driver name Probably caused by : ntoskrnl.exe ( nt_fffff80000b95000+51aa ) Followup: MachineOwner ---------
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
InformationWhy Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.
How Can we know that DV is enabled:
It will make the system bit of slow, laggy.
WarningBefore enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.
If there is no points, make a System Restore Point manually before enabling DV.
Let us know the results, with the subsequent crash dumps, if any.Tip
- If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
- If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.
