Random, Intermittent BSODs - Windows 11

OCCT GPU test results - let me know if there are any other OCCT tests you'd like to see

OCCT GPU test results - let me know if you have any questions

Closing the loop on previous observation - re: bad blocks. I ran a CHKDSK /B /V on the drive that replaced the faulty HDD. No errors - see below. CHKDSK for all other disks are posted earlier in this thred.
C:\Windows\System32>chkdsk /b /v e:
The type of the file system is NTFS.

Chkdsk cannot run because the volume is in use by another
process. Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) y
Volume dismounted. All opened handles to this volume are now invalid.
Volume label is Documents Music Pictures.

The bad blocks were moved to prevent continued use / lost data.

Please run all OCCT 1 hour tests and any other CPU stress tests to see if there is a confirmation of the prime95 fail > post images or share links

@zbook I think we are not connecting on the bad blocks discussion. The drive that had bad blocks has been uninstalled. The last chkdsk I posted is for a brand new drive that replaced the drive that had bad blocks. Are you saying you think another drive other than that faulty drive I removed also has bad blocks? If so, which drive and what are you seeing that brings about that conclusion?

Memtest is running right now. Will resume OCCT after.

Please run Memtest86 for 8 or more passes > take pictures > post images or share links

Memtest86+ | The Open-Source Memory Testing Tool

Just 1 error is a test fail and testing can be aborted.

The more the passes the better the testing conditions.

It sometimes takes passes into the 20's to detect malfunctioning RAM.

The RAM can be tested all at one time or one at a time in the same DIMM.

Memtest86+ | The Open-Source Memory Testing Tool

MemTest86+ - Test RAM



HD Sentinel by default will relocate bad blocks on all drives with available areas..

Memtest86+ 4 passes - both memory sticks - no errors. As a reminder, I have run memtest86+ against these 2 memory sticks at least 5 times each (4 passes) with no errors ever being detected. I'll run one more pass tonight just to confirm this.

Regarding HD Sentinal - I understand your information. I just want to be sure we are on the same page. The only drive that ever showed any bad blocks has been uninstalled. There are no drives installed that have ever indicated any bad blocks at any time. The errors in the latest event viewer records were related to the now uninstalled disk drive.

If Memtest86+ results display pass then plan to perform additional CPU testing or if readily available swap test the CPU.

At a later time a newer V2 can be scanned to make sure the bad block events disappeared.

Below are the links for the 2nd set of 4 passes - Memtest86+ (no errors). Per your previous post, I am running all of the available OCCT tests (1 hour each). Previous posts show CPU+RAM (no errors) and GPU (3D adaptive - 1 hour - no errors).

Unfortunately, the CPU is the one HW component I don't have a spare to swap. While I can and will purchase one as appropriate, I'm hoping for something solid to highlight a CPU HW issue.

See post #3.

And #79 and #86

All posts have one or more of these links:

Hi. Can you clarify why you’re pointing me to the posts?

Results of OCCT Linpack test (no errors detected) - continuing to run the remainder of available OCCT tests - will post as they finish

Results of Memory only OCCT test (NO ERRORS DETECTED)- proceeding to next OCCT test

The software to for memory testing have similar names but are different software.

Memtest86


Memtest86+ Free, unlimited passes

Memtest86 Free and pay versions. Free version limited to 4 passes. Pay version 8 passes with additional test types.

@zbook - thanks for the clarification. I'm using the free version doing 4 passes per run.
Here is the result of OCCT 3D Standard test - no errors. Continuing with OCCT tests

@zbook - heads up... during the OCCT VRAM test, a BSOD occurred "hypervisor error", my retest ran longer but a BSOD occurred before completion (IRQ). I'm doing another 2-3 tests to determine if this is consistent. If so, I will swap the GPU. Will update you as this situation progresses.

The variety of BSOD bugchecks were reported in post #76 which included 2001 hypervisor.

The thread findings so far have indicated malfunctioning hardware.

If the RAM is on the QVL and a lot of Memtest86+ passes are performed without error then swap test the CPU.

BSOD can occur at anytime with malfunctioning hardware.

Thanks and I understand. VRAM test completed - to your point, the Hypervisor Error and the IRQ have been occurring without any clear cause. I'll still run the VRAM test a few more times just to see if there is any correlation to the BSODs. Since the RAM is on the QVL as we discussed earlier in this thread and I've run at least 28 passes on the RAM, the CPU seems to be the most likely next target for a swap.

Update - see below screen shot of the POWER OCCT test - it appears to be the same core that Prime95 reported. I hope to have a CPU to swap test early next week. Will swap test and update accordingly. Thanks

Nice.

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

Or was the OCCT power test not performed earlier?
