[SOLVED] How to fix BSOD caused by Event 1001 BugCheck ?

[Lucaime]

My desktop computer has recently been fresh installed with Windows 11 Home and my CPU replaced. Many of my other parts were also tested due to BSODs. Since the fresh install I have had two BSODs occur 2 days ago on 6.19.25 soon after I turned on my PC and walked away. The most recent BSODs occurred after I had closed a video game. The first BSOD occurred about 1 minute after closing and then when the computer restarted the next BSOD occurred 5 minutes later. As of writing this no BSOD has occurred in an hour.

Since the replacement of my CPU I have been able to play games for 6-7 hours with no problems. I have never crashed during a game after the replacement.

I am hoping someone can review my dump files to shine a light on what could be causing this issue. I am losing hope that this issue can be solved. One additional comment concerning the dump files, the most recent BSOD dump file is inaccessible by my admin account. This is the only file that is inaccessible out of the 4.

Here is a link to the 3 BSOD dump files:

Thank you for the help.

Welcome to the forums, newcomer!

My desktop computer has recently been fresh installed with Windows 11 Home
Where did you source the installer for the OS? Did you install the OS in offline mode? Installing all necessary drivers in an elevated command, i.e, Right click installer>Run as Administrator, while in offline mode?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time. You state replacing your CPU, can you elaborate on what you replaced it with and why?

I used WinDBG to go through your .dmp files;
vgk.sys
seems to be the culprit in all 3. Have you tried uninstalling your anti-cheat app's and see if the issue persists?

Hello, thank you for the quick response. I had brought my computer to a repair shop nearby so they fresh installed windows. I believe they did it in offline mode via a USB because I had done a fresh install by downloading it from the internet prior and the guy said that was the wrong way to do it.

My Specs are the following:
CPU: INTEL CORE PROCESSOR I9-14900K

CPU cooler: CYBERPOWERPC DEEPCOOL LS520 ARGB AIO LIQUID CPU COOLER W/ ANTI-LEAK TECHNOLOGY 240MM

CPU Cooler Cont.: 2 CM ADDRESSABLE ARGB 120MM FAN 3PINS (RADIATOR ONLY)
CPU Cooler Cont.: DEEPCOOL CASTLE AIO LIQUID CPU COOLER RETENTION KIT (LGA1700)
Chassis Cooling: 6 CYBERPOWERPC ADDRESSABLE RGB DUAL LIGHT LOOP 120MM FAN 3PINS
Chassis: BLACK CYBERPOWERPC FURION MID W/FRONT, TOP & BOTH SIDE TEMPERED GLASS
Motherboard: ASUS PRIME Z790-P WIFI D5 DDR5 ATX W/ WI-FI 2.5GBT LAN 4 PCIE X16 1 PCIE X1 3 M.2 4 SATA LGA1700 CEC
Ram#1: ADATA XPG LANCER RGB 16GB DDR5-6000 MHZ MEMORY
Ram #2: ADATA XPG LANCER RGB 16GB DDR5-6000 MHZ MEMORY
SSD #1 (Boot Device): 500GB KINGSTON SNV2S NVME PCIE GEN4 M.2 SSD
SSD#2: 2TB SAMSUNG 870 QVO-SERIES SATA-III 6 GB/S SSD

GPU: NVIDIA GEFORCE RTX 4070 TI 12GB GDDR6X

PSU: APEVIA 1000WATT GOLD 80 PLUS W/ PCIE 12+4PIN CONNECTOR POWER SUPPLY

OS: WINDOWS 11 HOME ADVANCED DIGITAL LICENSE

1st Monitor: LG UltraGear 27GL850-B 27-Inch Nano IPS Gaming Monitor, QHD, 144Hz, 1ms, GtG, HDR 10, NVIDIA G-SYNC, Black

2nd Monitor: Dell S2419HGF


I purchased my computer almost exactly 2 years ago so that is how old the PSU is. My BIOS version/date is "American Megatrends Inc. 1820, 5/14/2025".

I ended up replacing my i9-13900K with an i9-14900K because of a few issues:
1.) I was failing CPU benchmark tests occasionally using 3DMARK.
2.) I was having trouble downloading new NVIDIA graphic drivers. The install would not complete and I could attempt it multiples times and it would randomly finally take the new driver. I tried fresh installs with DDU and manual downloads and could never get a driver to just download peacefully. When i took it to be repaired the guy fixing it tested the GPU, RAM, Motherboard... He put in a new GPU, Motherboard and when he replaced the CPU he was able to download graphic drivers. I sent my old CPU to CyberPower and they sent me back an i9-14900K as a replacement.

The guy said it could have possibly been my integrated graphics driver overwriting the NVIDIA driver or something similar to that.

Regarding my anti-cheat apps, the only one that I hate having on my computer is RIOT Vanguard so I went ahead and uninstalled it along with the RIOT Client and games. Any other anti-cheat app I can think of is baked into Steam games.

Thank you again for taking the time to look into my problem.

note: you have 14th gen intel cpu so you might want to read this:

3 bugchecks involving 3 different windows .exe, all had a call to vgk.sys driver. All taking a long time to happen.

SystemSettings.exe
StartMenuExper
SearchHost.exe

most likely this will turn out to be a bug with the vgk.sys Mon May 5 11:47:54 2025
driver. I would think the driver is using a pointer to kernel memory that is no longer owns. Windows will give the kernel memory to other processes, then The vgk.sys driver later uses the old memory address and corrupts the current owners data and the system crashes.

the only problem I saw with your build was with the nvidia gpu drivers, (different build dates) you might fully uninstall the nvida driver (gpu and gpu sound driver) and install the current version.

I did not see any corrupted windows files in the debugger.
note: you could also google how to make windows delete the pagefile.sys on shutdown, then make the registry changes and do a shutdown every day. (while you wait for a fix in the driver)
-----------------
rebooting more often is the only real fix I can think of for the vgk.sys driver until they get an update
the more memory you have in your system, then the less likely windows memory management will move data structures in memory, and the less likely you will hit this problem.
(reinstall the nvidia gpu and HDMI audio driver just to make your build less likely to have issues)

=======
you might consider removing the anti cheat software and reinstalling it. (for the case where the driver installs but the installed anticheat service does not match the driver version)



3rd bugcheck was also a stack overflow of the vgk.sys driver. (system uptime about 15 hours)
-----------
second bugcheck was also with vgk.sys driver.
system was running 1 day 15 hours
---------------
most current bugcheck looks like a stack problem with this driver:
vgk.sys Mon May 5 11:47:54 2025
vanguard anti cheat driver.
(system uptime was over 3 days)

will look to see if the I can see other problems, will take a few minutes.

I uninstalled RIOT Vanguard and waited a few weeks and I do not have blue screen errors anymore. Thank you both for your help!
