Occasional BSODs on a newly built gaming PC. Need help solving the issue.

I have been getting occasional BSODs on a newly built PC, with the computer slowing down and losing fps before crashing. Normally, the computer instantly restarts after crashing, but the past two times it has crashed, it remained on the BSOD screen, allowing me to see the stop code. The first was DRIVER IQRL NOT LESS OR EQUAL, and the second was DPC WATCHDOG VIOLATION. I have run memtest86+ on my computer for over 7 hours and it passed 9 times without any errors. There is also nothing in my C:\Windows\Minidump folder, which I checked after the most recent crash.

    In some cases it may be, but before testing another PSU you can try the steps I sent above if you haven't done so.

    There haven't been many complete freezes. Most of the time, there have been drops in fps (not in games, just in general) shortly before a BSOD. However recently, two times there have been long freezes before a BSOD. Would these still be signs that it is a PSU issue? And is there any way I can test if it is a PSU issue without replacing the PSU?

    If the problem is the PSU, the freezes should stop occurring.

    But usually BSODs are not caused by the PSU.

    If you are experiencing a lot of BSODs, have you tried these steps?

    Run SFC and DISM commands to scan and repair system files that may have become corrupted.

    Go to the manufacturer's website, search for your system/motherboard model and download the latest drivers and check if there is a BIOS update.

    Sorry, I only somewhat understand what you mean. The BSODs happen infrequently and randomly, sometimes multiple times or none during the day, meaning it would be tricky (though definitely possible) for me to test. I ask this mainly for convivence's sake: If changing the PSU fixes the issue, and I run driver verifier, would it simply BSOD but not actually show any errors in the logs, or not cause a BSOD at all?

    If the problem is the PSU, the freeze should stop happening.

    The driver verifier is just to force the BSOD to happen and create minidump files when Windows doesn't indicate what is causing it.
