Several random BSODs for the last few weeks, including Windows Update

Yes, you can't run anything on a computer that's turned off. Start Verifier and leave the computer on for two days. It won't hurt it. Mine is always on, I just turn off the display at night.

Alright, I'll leave it turned on. Anyway, it hasn't crashed yet.

Let Driver Verifier run for at least 36 hours - that's just a guess I made years ago.
Driver Verifier will (hopefully) crash the computer to a Blue Screen and collect a verifier enabled dump file that points to the actual problem driver. You'll zip up the dump file(s) (from C:\Windows\Minidump) and upload them with your next post. If you can't zip them there, then copy them to your Desktop and zip them there.

Most likely the USB devices are something that's connected/built into your motherboard.
Set a System Restore point, then go to the Gigabyte support page for your motherboard and install these Utilities:
- App Center
- On/Off Charge
- USB Blocker
- Windows USB Installation Tool (I'm uncertain about this one - skip it if you'd like)
Then check Device Manager to see if anything has changed (this is just a guess on my part - I picked out the USB stuff on the downloads page)
The other option is to disable the unknown devices and see what happens.

I've downloaded the first 3 utilities but no change in the Device Manager - the 2 devices are still unknown. I'll try disabling them later.

The computer needs to be running for 36 hours.
I prefer 36 straight hours - but again, this is a guess on my part

I just sat down at my PC (now's 22:45) and apparently is got another BSOD (once again IRQL_NOT_LESS_OR_EQUAL) at 05:18... I only logged in right before writing this reply, so the PC was turned on before and after that BSOD, but I wasn't logged on until now. I don't know if it counts towards the Driver Verifier time or not.

Anyway, here's the latest log collector ZIP: Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.

Check in Windows Update if there any updates of system
Uninstall 2 unknown devices through Device Manager

There's indeed a Windows Update:

• 2020-05 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4556799)
• Windows Malicious Software Removal Tool x64 - v5.82 (KB890830)
• 2020-05 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1909 for x64 (KB4552931)

I'll try to uninstall the 2 unknown devices, we'll see what happens.

So install it

Installed it. And since more than 48 hours since enabling Driver Verifier have passed, I've disabled it. Now what? Is there any logfile that it produces?

Uninstalled them, nothing happened.

I'm going to go out on a limb here and state that I suspect that it's a hardware problem.
So, I suggest starting with these free diagnostics:

- MemTest86 (4 passes): MemTest86 - Official Site of the x86 Memory Testing Tool

- Seagate Seatools for Windows (long/extended test on ALL drives); SeaTools for Windows |
Seagate

- OCCT (all tests): OCBASE / OCCT

- Furmark (run until temp's level out or there are problems - whichever comes first): FurMark > Home

- Prime95 Stress Testing (run for at least an hour - or until the temp's level out. If you get errors, STOP IMMEDIATELY): GIMPS - Free Prime95 software downloads - PrimeNet

Beyond that, I'd also suggest a "clean" install of Windows - BUT, don't try it yet (at least until we've discussed it in more detail):
- A clean install means no 3rd party drivers (we can discuss any needed exceptions)
- Any attached 3rd party devices must be dealt with prior to the installation.
- BIOS/UEFI is fully updated to the latest, stable release.
- There are no problems in Device Manager (we can discuss 3rd party drivers here)
- and you have ALL Windows Updates (to include hardware updates)
- Also, the system is set to default values (no changes in memory timings or anything else in the BIOS/UEFI) - NO OVERCLOCKING!!!

There are variants of the clean install all over the web. The point is that the system needs to be setup the way that the system or motherboard manufacturer initially setup and tested it. As this isn't always possible, we'll sometimes resort to doing it the way we think that Microsoft would've setup and tested it.
