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.
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
The sfc /scannow said that all system files were fine, and the ISO file, upon running it, told me that Windows is already fully updated and fine. Just out of curiosity, when I tried to do some research previously, specifically about the DRIVER IQRL NOT LESS OR EQUAL stop code, it said that it was a memory issue. As previously mentioned, I've already ran memtest86+ on my computer and it said everything was fine, but could there be an issue with the BIOS or something else related to memory?
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.

Repair your Windows using in-place upgrade:

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?
