PC crashing daily

Thanks for the update.

In this case, I have 2 suspicions about the cause of this problem.

1. Severe corruption of Windows.
2. A hardware problem.

It is possible to test some hardware components using software, but unfortunately, not all of them.

Before running any tests, make sure your two RAM sticks are physically installed in the correct slots on your motherboard. For your B450 Tomahawk, two modules must be installed in slots 2 and 4 (A2 and B2), counting from left to right. Running them in slots 1 and 3 can cause memory controller instability and blue/black screens, even with XMP disabled.

Next, I suggest you use the free MemTest86 tool for a deep check of your RAM.

https://www.memtest86.com/download.htm

The deep scan can take a long time, depending on how much RAM you have. So do it at a time that suits you.

Feel free to share a photo of the test result.

Also, check the health of your HD/SSD using Crystal Disk Info.

https://crystalmark.info/en/download/#CrystalDiskInfo

(On this same page, there is the download of another app. The "Crystal Mark". Do not download Crystal Mark. Download only the "Crystal Disk Info".)

Download the "Standard Edition" by clicking on the "ZIP" button.

Extract the ZIP and run the file "DiskInfo64.exe".

The health result of your HD/SSD will be displayed. See if there are any alerts.

Feel free to share a screenshot if you want. Use the shortcut "Windows + Shift + S" to use the screenshot tool.

Feel free to ask any questions you may have.

@David-M and the PC just crashed again. I found this in the event history: cldflt.sys and here is the minidump: https://1drv.ms/u/c/cbe42d931af4b952/IQCzhGBxyYk2R7oIR67EMDvxAd0_AfMhACllox7AHjG0TYQ?e=gkEwt2

Thanks for the update.

In this minidump, cldflt.sys (Windows Cloud Files Filter Driver) is mentioned, but the exception code is 0xC0000005 (Access Violation). This means the system tried to read an invalid memory address while the Search Indexer was running.

Having three different bug check codes across three different processes confirms that cldflt.sys is not the cause of the issue, but rather another victim of memory data corruption.

Crystal Disk Info did not detect any problems with your drives.

Please proceed with the other steps outlined in my previous reply. Verify the RAM slots, and run MemTest86.

Feel free to ask any questions you may have.

@David-M Hi David, I left memtest running and it didnt detect any errors. And I reinstalled windows a couple of months ago.

Thanks for the update.

Were you able to confirm whether your two RAM sticks are installed in slots 2 and 4 (A2 and B2)? Even though the RAM modules passed the MemTest86 test, this could still be a factor.

Also, try adjusting a CPU power setting in your BIOS. Your first minidump crashed while the processor was entering a low-power idle state.

(I put these steps together based on what I found online. However, some options might differ slightly on your motherboard. Please let me know if you come across any discrepancies.)

1. Restart your PC and press "Del" to enter BIOS;
2. Press "F7" to enter "Advanced Mode", then go to "OC" (or "Overclocking") > "CPU Features";
3. Locate "Power Supply Idle Control" and change it from "Auto" to "Typical Current Idle";
4. Press "F10" to save and exit.

Please let me know how it goes.

Feel free to ask any questions you may have.

@David-M Thanks for the help.
Yes, the RAM sticks are in the correct placement for dual channel.
I changed the settings now to Typical Current Idle.
I'll test it out today and let you know if I crash again.

Thanks for the clarification.

If you have any questions, don't hesitate to ask.

@David-M sadly it crashed again.
minidump: https://1drv.ms/u/c/2c0d7294ec101b5a/IQD6bxo-C27tTrchAmAcUQBSAYiqQnIqsqyfwL63ZjzF5BI?e=g9qppQ

Thanks for the update.

In this case, try resetting the BIOS settings to default.

1. Restart your PC and press "Del" to enter the BIOS;
2. Press "F6" (or look for the option) to "Load Optimized Defaults";
3. Save and exit by pressing F10.

Also, check your CPU temperature. Several tools allow you to monitor the temperature of your CPU. I recommend the free version of HWMonitor.

https://www.cpuid.com/softwares/hwmonitor.html

With temperatures slightly above 95°C, you can start to have problems.

The CPU temperature only increases when used. So do something on your PC so that your CPU is used to the point that its temperature increases.

Just open HWMonitor for the information to be displayed. There is no need to set anything.

Please let me know how it goes.

Feel free to ask any questions you may have.

@David-M someone on reddit told me that the minidump contains Kernel security check failure caused by League of legends's Riot vanguard.
What do you think?

In the last minidump you shared, the "LeagueClientUx" process is indeed mentioned, but I don't see any mention of Riot Vanguard.

Out of all 7 minidumps provided so far, only 2 mention "LeagueClientUx", while the remaining 5 crashed under completely unrelated Windows processes (such as System, svchost.exe, msedge.exe and SearchIndexer.exe). If all the minidumps had pointed to the same process, then I would have suspected it right away.

In the minidump, PROCESS_NAME indicates which application was actively running when the Windows kernel detected a corrupted memory block. When crashes occur across multiple completely different processes, it confirms a systemic/hardware memory corruption issue rather than a bug caused by a single application or anti-cheat driver.

At this point, I think it's a good idea to proceed with what I suggested in the previous reply.

1. Have you tried loading BIOS "Optimized Defaults" yet?
2. Were you able to check CPU temperatures under load with HWMonitor?

Please let me know how it goes.

Feel free to ask any questions you may have.

@David-M I left prime95 running for 30 minutes, it doesnt look like we have cooling issues.

And for the bios, I havent changed anything besides what you told me and fan curve

Thanks for the update.

Since we have already validated the hardware components, we are now down to two main possibilities:

1. Deep, non-repairable Windows system file corruption or driver conflict.
2. An elusive hardware issue (such as motherboard power delivery or processor memory controller degradation).

Are there any objections to performing a clean install of Windows?

Clean Installing Windows will remove all data stored on the system. Therefore, you will need to back up your personal files on an external drive or cloud storage service.

I'm considering suggesting you do this because instability problems don't survive a clean install unless the problem is caused by hardware.

Looking forward to your reply.
