WHEA_UNCORRECTABLE_ERROR - Random reboots and 0x124 error

Should I clean and reapply thermal paste?

cleaned my CPU & cooler w/ isopropyl alcohol and qtips ... both were sparkling clean. Applied a pea size (or a bit less) of arctic silver, and my first core is still hitting 100 degrees. Not sure what else I can do here ... the cooler is sound, the fan is good. Could it be a bad CPU? Do we think there's still something WRONG with the CPU?

For the CPU this Intel link may be useful: How to Apply Thermal Interface Material (TIM)

The CPU testing temperatures remain high.

Thank you. I used the exact methods described above, but I'll review the documentation once again in the morning.

TBH, cleaning the top of a CPU and the heat sink, reapplying a pea sized amount of Arctic 5 to the CPU, then securely remounting the heat sink is pretty simple... I've done it a dozen times.

Not trying to be snarky. I really do appreciate all the help you've provided.

The latest bsod was not able to be completely debugged with the command unable to work during this Windows upgrade period.

I do not understand this comment - I have no problems using WinDBG to analyse crash dumps from the Fall Creators Update. All the symbols for this build are loading correctly as far as I can tell. The commands like !thread are all working as they should.

I suggest that the OP runs without Driver Verifier on and we wait for any new BSOD on this Fall Creators Update before making any further suggestions.

The current BIOS Version/Date American Megatrends Inc. 1.50, 6/27/2017
Please check the MSI website to see if the July BIOS update is applicable to the computer:

Please check the CPU warranty status for RMA.


@philc43 !thread windbg command not working in any dump I look at

@zbook please message me privately - we need to get you sorted with WinDBG - you must be using an old version. The !thread command only fails for me on some of the 15063 builds.
