Random, Intermittent BSODs - Windows 11

That’s a great question. I think I ran the power test but it may have before the series

Nice.

Had this passed with prior testing (post #77) reported earlier?

Or was the OCCT power test not performed earlier?

That's a great question. I was just reflecting on the progression of this issue last night. I began battling BSODs literally the day after upgrading to Win 11 (Nov 2023). In reflection, I think I went through different phases of issues. When I first ran OCCT, I'm pretty sure I ran all the tests but I don't recall having the Hypervisor & Kmode BSODs during that phase. My recollection is that the Hypervisor&KMODE errors began sometime in the past 2-3 months and I may only have run the CPU & CPU+RAM & GPU tests during that phase.

Time will tell after the CPU swap but my lesson learned out of this was that I should not have assumed I had the same root cause of BSODs through-out this process. I've been reading about people having experiences with the Ryzen 5 3600 "degrading" and having issues with specific cores - that may be what has happened in this case.

results of Furmark test below - I see nothing of note

Results of Prime95 test below - one notable item (worker #2 failed early in test). Unsure of significance. Have run 2 other CPU testing tools extensively with no issues noted but this does get my attention. Temps got up to 95, 96C a few times throughout test but did not stay there log. I didn't see anything of note in voltages.

Looks like bugcheck "A", because processor not stable. Prime95 failed as well!

Edit: OCCT failed as well, for what you said is the same core.

Yes. Already planning a cpu swap test

Finally ready to swap test CPU - will install tomorrow and report back with OCCT and Prime test results as well as whether any BSODs occur after swap.

Please post a new V2 anytime before the swap.

Good idea. Will upload tomorrow before swap.

OCCT and Prime95 tests ran without error. Will be watching for BSODs - reminder, the BSODs have been unpredictable in the past (sometimes a few in the same day and sometimes 7-10 days between BSODs). Will update and (if no BSODs) do a recap to summarize what I think happened.
Thanks!

It has been 6 days since the CPU SWAP test with ZERO BSODs - not the longest period since this problem began but, combined with zero failures from OCCT POWER TESTS and Prime95 tests, I believe the problem(s) is/are gone.

First - @zbook - Thanks! for your patience and persistence through this matter.
Second - for those following or just now reading this thread... below is a recap of what I believe was the sequence of events (in case this helps you with similar issues)

1. While running Windows 10, this computer was 100% stable with no BSODs. Upon upgrading to Windows 11, BSODs began happening frequently (sometimes multiple per day). The bugcheck codes were varied but it appeared multiple drivers were broken by the upgrade. Presumably, because many of the drivers were not up to date.
2. While finding and fixing all the affected drivers, I believe the numerous BSODs caused significant corruption causing further BSODs with even more varied bugcheck codes (some of which are listed in earlier in this thread).
3. Finally, after doing a clean install of Windows 11 with fully updated drivers, I believe one of the cores of my Ryzen 5 3600 CPU began failing. The failure was intermittent and not obvious - it was causing 3 specific bugcheck codes - Hypervisor Error, Kmode and IRQ. Testing with OCCT (POWER TEST) and Prime95 both confirmed an issue with the CPU which was causing these BSODs.

Lessons learned:

1. I should have updated all drivers prior to the Windows 11 upgrade.
2. With so many BSODs a clean install was needed to address Windows 11 corruption
3. Don't overlook potentially new BSOD causes when diagnosing existing failures (especially when new/unusual bugcheck codes appear)
4. When a CPU issue is suspected, comprehensive testing is required. I ran OCCT and other CPU tests numerous times (presumably, before the CPU failure) and I ran SOME of those tests after the time I now know the CPU began failing, but not all of them. I also had never run the Prime95 test before. Finally, the OCCT CPU test did NOT fail against the faulty CPU but OCCT POWER testis consistently failed indicating a CPU issue.

Thanks again to @zbook and others who provided input.

You're welcome.

Glad to help.
