Windows 11 BSOD every few hours

Question

Windows 11 BSOD every few hours

William Kendell 0

I reinstalled my graphics drivers and wifi drivers from intel but it's still crashing with the same error code, DRIVER_IRQL_NOT_LESS_OR_EQUAL

there was a USB-A phone charger i plugged in before the crashes started but that was removed long before i reinstalled all of that other stuff

Hi William Kendell,

Since the crashes are occurring repeatedly with the DRIVER_IRQL_NOT_LESS_OR_EQUAL stop code and reinstalling the Intel graphics and Wi‑Fi drivers has not resolved the issue, the next step is to identify the specific driver or component triggering the crashes.

Please try the following checks:

1, Update your BIOS/firmware

Visit your PC manufacturer's support site.
Install the latest BIOS and chipset updates available for your model.

2, Run a memory diagnostic

Press Windows + R and enter mdsched.exe
Select Restart now and check for problems.

3, Perform a Clean Boot

Press Windows + R and enter msconfig
Hide Microsoft services and disable remaining third-party services.
Restart and monitor for further BSODs.

4, Analyze the dump files

Open the minidumps in WinDbg and run: !analyze -v
Share the resulting MODULE_NAME and IMAGE_NAME entries, as these can help identify the driver involved.

The stop code you're seeing is commonly associated with a driver accessing invalid memory, so identifying the exact driver from the dump analysis will help narrow the investigation considerably.

It's tcpip and tcpip.sys.

Hi William Kendell,

Thank you for checking the dump files. Since the analysis points to tcpip.sys, the crashes appear to be occurring within the Windows networking stack. This does not necessarily mean tcpip.sys itself is the underlying cause, as a third-party network driver or filter can also trigger a crash at this point.

Since you have already reinstalled the Intel Wi-Fi driver, I suggest checking for other networking components:

Temporarily uninstall third-party VPN, firewall, or network-filtering software, if any is installed, then restart and monitor the PC.

Update the Ethernet/LAN driver from your PC or motherboard manufacturer's support page, even if you normally use Wi-Fi.

If the BSOD happens again, check the WinDbg !analyze -v output for IMAGE_NAME, MODULE_NAME, and the lines under STACK_TEXT immediately around tcpip.sys. A non-Microsoft driver listed there could help narrow down the actual cause.

I hope this helps narrow it down. If you can provide the relevant !analyze -v output, it should give us a much clearer direction for the next step.

I don't see anything out of the ordinary in the STACK_TEXT, what about you?

Hi William Kendell,

Thank you for sharing the stack trace, and I agree that there is no obvious third-party driver shown in the STACK_TEXT.

The crash occurs while the Windows networking stack is processing UDP network traffic, with tcpip.sys and NDIS appearing in the call stack. However, this does not necessarily mean tcpip.sys itself is the underlying cause, as another networking component could have passed invalid or corrupted data into the stack.

If you have additional dump files, please compare their WinDbg !analyze -v results, particularly:

FAULTING_IP

MODULE_NAME

IMAGE_NAME

FAILURE_BUCKET_ID

If several crashes consistently point to the same tcpip function or network receive path, that pattern may help narrow down what is triggering the BSOD.

Answer 2

DRIVER_IRQL_NOT_LESS_OR_EQUAL usually points to a faulty or incompatible kernel-mode driver. Since the Intel graphics and Wi-Fi drivers were already reinstalled and the same stop code continues, focus on identifying the exact driver or recently changed hardware/software.

Recommended next steps:

Check Event Viewer for the failing driver
Open Event Viewer and review the System log around the crash time for errors that identify the device or driver involved.
Check Device Manager for problem devices
Right-click Start > Device Manager. Look for any device with an exclamation mark.
- Right-click that device and select Update driver.
- If updating does not help, try Disable device or Uninstall device.
Install all Windows updates, including optional driver updates
Go to Start > Settings > Windows Update > Advanced options.
- Turn Receive updates for other Microsoft products to On.
- Open Optional updates and install all available updates.
- Return to Windows Update, select Check for updates, install everything available, and restart.
Use the PC manufacturer’s drivers, not only Intel’s generic packages
If Windows Update does not resolve it, install the latest device-specific drivers from the PC manufacturer, especially for:
- graphics
- Wi-Fi/network
- chipset
- BIOS/firmware
Remove any recently added hardware
If any hardware was added before the crashes started, remove it and test again.
Check free disk space
Keep roughly 10% to 15% free disk space available so Windows can create swap files and operate normally.
Test in Safe Mode
Start Windows in Safe Mode and observe whether the BSOD still occurs. If it stops in Safe Mode, that strongly suggests a driver or service loaded during normal startup.
Review non-driver causes called out for IRQL errors
This stop code can also be triggered by:
- faulty system memory
- a system service
- BIOS issues
- antivirus software
- incompatible software during or after upgrades
Temporarily remove or disable recently installed low-level software
If any antivirus, backup tool, VPN, anti-cheat, or hardware utility was installed or updated before the crashes began, disable or uninstall it temporarily and retest.
If the issue started after a recent change, use recovery
If the crashes continue, restore Windows using a restore point or another recovery option.

If a specific driver name appears in the bug check message or Event Viewer, that driver should be disabled or replaced with the version from the device manufacturer.
