Question Newly built PC keeps hard freezing/ showing BSOD's

[Deleted member 2964455]

I've just made an account, so I hope my question fits here and that the formatting/info is right.

I've recently built a new PC together with my younger brother, but we can't get it to work properly.
Components:

• CPU: Intel Core i9-12900k 3,2GHz
• GPU: ASUS TUF Gaming GeForce RTX 3070 Ti OC
• PSU: Sharkoon WPM Gold ZERO 750W
• RAM: 2x 8GB Corsair DDR4-3200
• MOBO: Gigabyte Z690 Gaming X DDR4 (rev 1.0)
• HDD: Seagate IronWolf 4TB
• SSD:
• CPU-fan: Pure Rock 2 Black
• Case: Be Quiet! Pure Base 500

After finishing the build we booted it, and the VGA-led stayed on on the motherboard, while the monitor did not get a signal. Rebooting it either resulted in the same situation, or the monitor turning on, but then the PC would freeze randomly (only hard reboot worked).
During the moments it did work, we updated the BIOS to the latest version, download drivers, but it did not solve the issue. We also removed/replaced/switched the RAM, removed, switched and changed HDD's and SSD's, we removed the dedicated GPU and reinstalled Windows/BIOS, with no changes.
Desparate as we were, we sent the CPU back to see if something was wrong with it. Apparently a pin was slightly bend, but they were able to straighten it.
After this the freezes/BSOD's kept on happening though.

Long story short we gave up for a year and let the PC collect dust in a corner.

Today we tried again, hoping that the issue miraculously dissapeared or that a new update would solve everything. It didn't. But we found some clues:

• During Windows Update (installing Windows 10 22H2) it crashed at exactly 25%, four times.
• When installing Intel Graphics drivers using the App Centre it repeatedly crashed, too
• When installing the same driver using safe mode, there were NO errors
• After installing the graphics driver in safe mode, Windows Update installed Windows 10 22H2 without any problem
• Leaving the PC on idle for hours gave no problems whatsoever
• Updating to Windows 11 and the PC crashes again at 12%, every time.

When freezing or crashing during the situations mentioned above we got a BSOD, either a WATCHDOG TIMEOUT or a WHEA error, after which the PC rebooted as it is supposed to.

Now, the last thing we tried was Intel's CPU Diagnostics Tool. We tried it thrice, three times the PC froze. The first time it hard-froze. No BSOD. Second time a WHEA BSOD that froze at 60% and lastly a TIMEOUT BSOD that froze at 20%. No automatically performed reboots.
This makes me think that it's the processor or the Mobo. But I would like some help from people that have more experience with this than I do. I have added the 4 most recent dumps and uploaded them here on Mediafire.
These 4 are all results from running the Intel CPU Tool: 1st is from the first test/crash. The 2nd is from a crash right after booting after the 1st crash. The 3rd and 4th are both from the 2nd and 3rd try at running Intel's tool.

Do you have another psu you can use? Your dmp files point to two hardware errors, and last two indicate high cpu usage/calling one specifically pointing to win defender/win update.

Thanks for your reply!
No, sadly I don't.

Could you explain why you think it would be the PSU, if it's the CPU that's showing up in the dumps & it fails with no exceptions when running the Intel CPU software?

I know the 750W Sharkoon might be on the lower end, but we also experienced these crashing without the 3070 (using the onboard gpu), so I thought the wattage couldn't be the problem. I read that the i9 12900k uses 241W at most during turbo mode and I think the Sharkoon should be able to handle that. Or is my thinking wrong?

Sometimes lower end psu's come up a dud, even high-end on es. It is just a troubleshooting step to take before you go nuclear and return motherboard or the cpu.
