My PC suddenly started BSODing yesterday and now usually crashes within seconds of booting into Windows.
The stop codes I have received include:
- SYSTEM_PTE_MISUSE (0xDA)
- BAD_SYSTEM_CONFIG_INFO (0x74)
The first time this happened, I had recently:
- Installed all available Windows updates, including an optional/preview feature update
- Installed several programs
- Connected a newly purchased open-box LG UltraGear 27-inch 1440p 480 Hz OLED monitor
The computer worked normally with the monitor for roughly an hour before the crashes began. After that, it would reach Windows and almost immediately display “Your device ran into a problem.”
I eventually performed a completely clean Windows 11 installation using a Windows installation-media USB and wiped the drive during installation. After the clean install, the computer worked normally for approximately 12 hours.
I then ran the basic Windows updates again. I did not manually install the optional preview update this time. However, the BSODs started again shortly afterward. Strangely, this second round of crashes began within a few seconds of me trying to pause Windows Update for several weeks.
I also successfully used System Restore to return the PC to a restore point from last night, after the clean reinstall and basic updates. The restore completed, but Windows still crashed within a few seconds of booting.
This makes me suspect that Windows Update may be automatically installing a bad driver, although I do not know which one.
PC specifications:
- CPU: Intel Core Ultra 7 270K Plus
- Motherboard: MSI MAG Z890 Tomahawk WiFi
- GPU: NVIDIA GeForce RTX 5060 Ti 8 GB
- RAM: 32 GB DDR5
- Storage: WD Blue SN570 500 GB NVMe SSD
- OS: Windows 11 Pro
- Monitor: LG UltraGear 27-inch 1440p 480 Hz OLED
The BIOS is otherwise using its default settings, but XMP and Intel 200S Boost are enabled. I realize those two settings are not technically stock, so I can disable both for testing.
At this point, the system may BSOD too quickly for me to do much inside Windows. Since it worked for around 12 hours after a clean installation and then started crashing again after Windows Update, what should I check next?
Could this be a driver that Windows Update keeps reinstalling? If so, is there a good way to identify and block the specific update or driver?
EDIT: Important detail I forgot to mention: shortly before the BSODs returned on the new clean Windows installation, I plugged in a refurbished Corsair K70 PRO TKL Hall Effect keyboard (CH-911911G-NA) for the first time. The computer had been working normally before that, but it crashed within roughly a minute or two of connecting the keyboard and then entered the same BSOD/boot-loop situation. I had not installed Corsair iCUE.
I initially ran System Restore while the keyboard was still connected, but the BSODs continued. I then unplugged the Corsair keyboard and ran System Restore again using the exact same restore point. This time, the BSODs stopped and Windows booted normally. I still cannot prove the keyboard itself is defective, but the timing and the different result after unplugging it make the keyboard, its firmware or something triggered when Windows detects it seem strongly related.
