We’ll start by looking at a few quick fixes which might fix the irql_not_less_or_equal error and then move on to more advanced options. But before that, let’s. I have a Razer Blade Stealth (not the new one) QHD 256GB, it has already had some other problems, but thus far they were all software issues. I have experienced BSODs.
There were 4 bsod mini dump files that were debugged. There was no msinfo32 to troubleshoot. There was no dxdiag to troubleshoot. There were 3 misbehaving drivers identified: 1) bwcw10x64.sys (Killer Bandwidth Control Filter Driver) 2) Qcamain10x64.sys (Qualcomm Atheros Extensible Wireless LAN device driver) 3) VBoxNetLwf.sys (Oracle VirtualBox NDIS 6.0 Lightweight Filter Driver) To update drivers: Updating a driver: Perform the following test: Run memtest86+ version 5.01 for at least 8 runs.
This may take many hours so plan to run it overnight. To perform a proper test it is done by passes and not by time. Tests need to be 8 or more passes otherwise there is a significant number of false negatives.
A false negative is a pass when there is malfunctioning RAM. The computer has 32 GB of RAM. Memtest86+ testing takes approximately 1 -2 hours /GB RAM If you cannot be without the computer for this duration of time you can test 1 RAM at a time in the same DIMM. Testing 1 RAM at a time though will not test dual channel capability of the DIMM/MB So test both at the same time is preferred. If there is just 1 error that is a fail and you can abort testing. Then test 1 RAM at a time in the same DIMM.
Test each RAM for at least 8 passes. If both RAM pass when tested separately but fail when tested at the same time you will need to test the DIMM / MB by testing RAM in the next DIMM.
When Memtest86+ has completed 8 or more runs use a camera or smart phone camera to take a picture and post an image into the thread.
FIX BSOD Error: DRIVER_IRQL_NOT_LESS_OR_EQUAL(ndis.sys) on Windows 10 After you upgrade the system to Windows 10, the PC runs into the BSOD error. It shows as Driver_IRQL_NOT_LESS_OR_EQUAL (ndis.sys). And of course, you will see the different.sys files such as ndu.sys, netwtw02.sys, tcpip.sys, epfwwfp.sys, etc. Other BSOD errors: Mostly, this is because of the network driver issue. So you can try to solve the network driver issue to solve this BSOD error. Of course, if you can enter windows 10 in normal mode, you can also do all the next steps in the normal mode.
If in normal mode, you cannot solve it, try to enter the safe mode do these again. Type device manager in the search box to open device manager. Expand Network adapters, and find the network device. Right-click it and choose Uninstall to uninstall the device driver. Click OK to confirm uninstall the device. After that, click Scan for hardware changes in the toolbar to reinstall the driver.
If your computer also had the DRIVER_IRQL_NOT_LESS_OR_EQUAL error, you need to download the network driver from the manufacturer’s website and install it manually. If you had already installed wireless driver, you need also download the latest wireless driver for it. This will help to solve netwtw02.sys error.
Also, for an easier way, you can use to download and update network driver to solve the BSOD error. Driver Doctor is professional driver update software to help you fix the outdated drivers and error drivers. After you run the Driver Doctor, it will scan all your PC devices. Then find the outdated drivers and problem drivers including network driver. You can download and update your network driver with Driver Doctor directly. After that, reboot your computer, you will find the BSOD error is solved. For the DRIVER_IRQL_NOT_LESS_OR_EQUAL (epfwwfp.sys), you can also solve it by this way.
1. Right-click Win icon and choose Command Prompt (Admin). In command prompt, type this command: DEL /F /S /Q /A 'C: Windows System32 drivers epfwwfp.sys' Then press Enter key. After that, the system will help to delete the dpfwwfp.sys file. So your dpfwwfp.sys BSOD error will be solved.
If it reminds you that could not find the epfwwfp.sys, you can try to follow the above way to uninstall and reinstall network driver to solve it.
