Easy Ways to Solve Ndis.sys Failed BSOD Problem
Ndis.sys is a system file that is needed by the Windows operating system. By default, it is stored in the C:WindowsSystem32drivers path and serves as a repository for system driver settings that are used to communicate between Windows and connected devices/hardware.
In most cases, the file would not cause any harm to the machine. However, issues with the ndis.sys file, such as ndis.sys failed BSOD (with the error message driver_irql_notless_or_equal) and high latency, which arises as a result of bad system drivers, hard disc damage, or other factors.
Fortunately, you can resolve the ndis.sys failure problem on your own. Since blue screen errors are always accompanied by data loss, it is often a good idea to use data recovery software after a BSOD. You can now boot into Safe Mode and begin troubleshooting with the following solutions after all necessary data has been restored and backed up.
Method 1: Update Your Drivers
The most popular cause of ndis.sys latency or blue screen error is an outdated/corrupted driver. As a result, you should update your drivers first (especially network drivers and drivers with an exclamation mark). To do so, complete the following steps:
Step 1: To open Device Manager, press Windows + R to open the Run window, then type devmgmt.msc and click OK.
Step 2: Select Update driver from the context menu when you right-click the driver you want to update.
Step 3: Select Search automatically for modified driver software to have Windows search the internet for the required driver. Then, to complete the driver update, please follow the onscreen instructions.
Note: If this doesn’t work or solve the problem, you should try reinstalling or rolling back your network drivers.
Method 2: Scan for Malware/Virus
Some malware entities can impersonate ndis.sys, causing various ndis.sys issues. Having said that, scanning your machine for ransomware, Trojans, and possible viruses is critical.
If you didn’t install any third-party antivirus, you can use Windows Defender to uninstall the malware from your device. Simply follow these steps:
1. Go to the Windows Configuration menu.
2. Go to Update & Security Virus & Threat Defense in Windows Security.
3. Click Run a new advanced scan in the new window and choose Full scan.
4. To begin scanning your screen, click Scan Now.
Restart your machine after eliminating any possible threats to see if this strategy works.
Method 3: Employ System File Checker
If the above simple solutions don’t work, it’s possible that some relevant device files (including the ndis.sys file) are corrupted or missing. If this is the case, you can use the Machine File Checker tool to resolve the problem.
1. To open Command Prompt with administrative privileges, type cmd in the Run window and press Ctrl + Shift + Enter.
2. To begin scanning, type the command sfc /scannow and press Enter.
3. Wait patiently until the machine check is finished 100 percent.
If any corrupted files are found, exit the tool and restart your computer, which will replace the problematic system files with a cached copy.
Method 4: Check Hard Drive Errors
Aside from the reasons mentioned above, a corrupted hard drive may also cause ndis.sys issues. As a result, it’s a good idea to search your hard drive for file system errors.
Checking for hard drive errors isn’t as complicated as you would imagine. Simply detach the troublesome computer’s hard drive and connect it to a working unit. Then, using a reputable hard drive test utility, you can begin testing for errors on your hard drive.
After that, reconnect the hard drive to the device that is showing the ndis.sys failed error. Your machine should now be able to function normally. If the error still prevents you from starting your computer, proceed to the next step.
Method 5: Perform System Restore
If none of the above solutions work, consider performing a device restoration to restore your Windows to the state it was in before ndis.sys failed. This approach is widely used to address a number of device problems, and it has no effect on your personal details.
To successfully restore Windows to a previous date, make sure the system restore function is turned on and that at least one system restore point is established. Even if you didn’t make one, you can always try because Windows provides a restore point for you when something significant happens to your computer.
