unlikely, where did you purchase it from?
which bios version is installed?
examine the thermal paste and cooler once more. 100°C isn’t typical; you don’t need to undervolt under normal conditions to achieve lower temperatures.
is your windows energy plan configured for balanced or high performance?
did you set up windows with this new hardware recently?
Well, my nation isn't part of the EU, so I consistently purchase PC components from Hungary. The costs are more favorable and the items are of superior quality – I haven’t encountered any problems over the past fifteen years in this way. I never have had any issues with RMAd anything.
The BIOS version is the most recent one, 7D91vHG, released on April 22nd of this year.
I might have misplaced my thermal paste; I applied a Noctua paste in the X pattern, placing a few small dots between them. The CPU only reaches 100 degrees, and it throttles during CPU-intensive tasks such as unpacking heavily compressed files and stress tests. After undervolting, I repeated the tests and everything functioned perfectly. For extended gaming sessions, for example, playing Oblivion Remastered at 1440p with ultra details, I managed to play for four hours without any crashes, hiccups, stutters, or BSODs. It also performs well in other titles. If the problem continues, I’ll take my PC to a service center so they can reapply the paste.
I use a balanced plan in Windows, with sleep and hibernation disabled. My PC typically runs smoothly for days without being shut down, so I rarely turn it off. This particular BSOD was the first cause (after 16 days) that prompted me to restart my machine.
The Windows 10 installation is up-to-date, with the latest updates applied. All drivers are current, sourced from official sites. My components are new except for the hard drive, which serves only as storage. I’ve used some third-party tools to remove unused (greyed-out) drivers just to ensure there are no conflicts or duplicate entries.
What I did while waiting:
- Ordered a new web camera
- Disabled fast startup and fast boot to confirm everything stabilizes post-shutdown
- Deleted unused devices and drivers safely
- Removed certain Chrome extensions, as they frequently cause me to log out unexpectedly and trigger 'Aw, Snap!' crashes (note: this includes all previous BSODs plus the latest one while Chrome was running in the background)
- Performed a memtest86 run for eight cycles; RAM appears healthy
- Plan to conduct an OCCT stress test for an hour to verify CPU performance
Which tools exactly? Or did you apply them once the issues started?
Undervolt and attempt a quick startup again.
Initially, I removed my Razer mouse drivers using Driver Store Explorer so it would be recognized as any standard mouse. This was about two weeks ago. Now I'm using a Logitech G102. After experiencing this BSOD, I ran NirSoft's USBDeview to check for duplicates and verify USB device functionality, which confirmed everything is working. I plan to perform the OCCT test after work today before any undervolting. If I encounter errors or another BSOD, I'll rerun it without undervolting and then share the outcomes. It's currently 10:22, so I intend to complete all tasks by 3:30 PM, so you know when to expect my updates. In the meantime, I might visit a PC store to reapply paste, but if OCCT succeeds with the current undervolt setup, I think further action may not be necessary.
don’t rely on driver tools. based on my experience, they often cause more issues than they fix.
visit https://www.malwarebytes.com/ if you notice anything unusual.
OCCT test completed; CPU, RAM, and VRAM checked for one hour. Undervolted at -0.140, RAM XMP enabled at 6000 MHz, CPU tested at Extreme level – no problems detected.
The highest CPU temperature reached was 92 degrees.
Does this eliminate hardware concerns?
I can run malwarebytes to verify, but I’m uncertain it will detect anything since my OS is new and I haven’t done anything unusual.
My next step is to use Driver Verifier. Any advice?
After interacting with Verifier, the system displayed a BSOD with the error code DRIVER_VERIFIER_IOMANAGER_VIOLATION and the message Wdf01000.sys. The analysis using ChatGPT pointed to possible issues related to storage or power management, likely because the crash occurred before Windows fully loaded. Additional files detected included WppRecorder.sys, which may indicate kernel event logging, and a file named storport.sys, suggesting a potential ASRock-related problem. The dump file is available for review at the provided link.
After handling the driver verifier, I removed Unified Remote since it was the main issue. It turned out G-HUB was the real culprit, along with my outdated webcam driver. Deleting G-HUB and the camera driver seemed unusual. This webcam performed well on my old PC, yet both Razer and Logitech drivers caused BSODs on my new PC. Is this just a coincidence or does it point to a more serious problem with my USB controllers or chipset?
I refreshed the file and its performance metrics are stable. It's solely used for storage, with nothing vital saved there, though I recognize it might lead to complications.
I think the primary issue stemmed from my camera, which is nearly two decades old. The Z790 motherboard and its latest chipset seem to be the root cause. G-HUB and Unified Remote were triggering BSODs only when using verifier, since the verifier is highly sensitive to these low-level kernel operations. I removed and unplugged my camera (holding off for the replacement) and reinstalled Unified Remote – no problems encountered so far!
I’ll monitor everything carefully to ensure the problem is resolved.
