What Causes DRIVER_IRQL_NOT_LESS_OR_EQUAL?
Upon turning on computer you find staring at a blue screen with the DRIVER_IRQL_NOT_LESS_OR_EQUAL code, there's possibly an issue with drivers.
The DRIVER_IRQL_NOT_LESS_OR_EQUAL bug check has a value of 0x000000D1. This indicates that a kernel-mode driver attempted to access pageable memory while the process IRQL that was too high.
Causes of this Error
This error has been known to occur as a result of one of the following causes:
Cause 1: Incompatible hardware device configuration
If you encounter this error on a brand new PC, after upgrading any of the hardware components in your computer, or when connecting an external device, this error is caused by a resource conflict between two or more internal or external devices connected to your computer.
Cause 2: Corrupt system files
If this error started “out of the blue” and did not happen after installing, connecting, replacing, or upgrading any PC hardware or components, then the most common cause for this error is a corrupted system file that is required to boot the system. This can happen because of virus attacks specially designed to cause IRQL_NOT_LESS_OR_EQUAL errors, power outages, or disk write errors during Windows system or manufacturer driver updates.
Cause 3: Incompatible device drivers
Another common cause is a newly installed or recently upgraded faulty device driver. In that case, reverting to an old version of a driver would be the best solution.
Cause 4: Faulty hardware items
This error can also be caused by a damaged motherboard, a bad RAM module, or failing internal/external hardware or components.
Cause 5: Incorrect software installation
Sometimes, this error may be caused by a misconfigured Windows service or registry error. This is typically the case if you run into this after installing a Windows update or after your PC says “applying updates,” or after manually installing an update to a driver.
Cause 6: A downgraded Windows installation
The least common cause for this error is when an older version of Windows is installed on top of a newer one. Sometimes, the system files are not replaced properly, and if that is the case, then the user should back up the files and perform a clean install to make sure there are no conflicts between different versions of Windows.
A "netio.sys" error, otherwise known as the same-driver incorrect memory address issue, is caused when a driver mistakenly accesses or creates an inappropriate memory address while performing its duty.
What is Bluescreen 0x000000d1?
Bluescreen 0x000000d1 error (or Bluescreen of Death Windows or STOP: 0x000000D1) is a driver related issue wherein some files get corrupted causing the system screen to turn blue with an error note which reflects bluescreen 0x000000d1 error code .
Sometimes it occurs during windows start-up process too, thus making your system inaccessible. It occurs when the recently installed driver or software starts behaving abruptly and an error message like “DRIVER_IRQL_NOT_LESS_OR_EQUAL” appears. This reflects that the windows program has crashed or might shut down suddenly.
Cause of bluescreen 0x000000D1
Getting an error like 0x000000d1 sometimes become unprecedented and before to think of rectifying the issue, it is always helpful to know what causes the issue.
Therefore, below are mentioned the cause of bluescreen 0x000000d1 error.
· Install driver is corrupted
· The driver was not installed properly
· Some internal files of the system get corrupted
· Sometimes antivirus/security also causes an error
· System service issue or System file corrupted
· Incompatibility of the backup tool while upgrading of the system
How to Fix bluescreen 0x000000D1
Need to know different methods as per system error, just need to go through them one by one to resolve the issue and make the system ready to start work again.
Let’s move on to learn how to resolve the issue with following methods
Solution 1: Fix the System
System file checker is the utility tool for the Windows system whose primary function is to look for any corruption of data by scanning the windows system and then restore the corrupted files.
Following are the steps to run the System fix checker tool (extension- SFC.exe)
1. Launch Command Prompt
2. Run as administrator
3. Enter password ( If any)
4. Apply
5. Enter sfc /scannow
Once Entering the Command, it will start scanning all the system files, check them, if it finds any corrupted one it will replace that corrupted file. Also, keep the Command Prompt Open till verification process gets completed.
The following result messages shown such as:
1. Did not find any violations
2. Could not perform the operation (In this case, you need to run System checker in a Safe Mode)
3. Corrupted files are found and repaired successfully
4. Corrupted files are found but were unable to fix some of them by Windows Resource Protection.
In this case, need to go through the Manual rectification process. Also, need to check which file is corrupted, to do that:
1. Open Command Prompt
2. In the command prompt use following command,> then press Enter
3. findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log>"%userprofile%\Desktop\sfcdetails.txt"
This command will let you know which file is not repaired, check date and time when the last time it ran on system checker.
1. Now, the process to manually replace process to the corrupted file
2. Type the following code then press enter: takeown /f Path_And_File_Name
Now type the following command then enter it : icacls Path_And_File_Name /GRANT ADMINISTRATORS:F
Now to replace the corrupted file with the Good known copy of the file, use the following command: Copy Source_File Destination
Here source file- Is the Good known copy from your system and Destination file- Is the corrupted file
This way you can successfully repair the corrupted file through System Fix.
Solution 2: Update Driver
What if the issue is due to some driver, how to go about?
Well, the most striking fact is lies in the bluescreen itself.
Actually, the driver name is mentioned next to the error, such as xyz.sys or xxx.sys.
Now as you know the issue is due to that particular driver, so you need to either update or remove that driver, due to which this issue occurred.
Solution 3 : Use Driver Update Software
This Driver update Software will scan your system automatically, check any of the outdated drivers and easily update that.
Solution 4: Fix Blue Screen Error by Restoring System
If the issue is due to the faulty driver, BIOS, system service issue, then you need to follow the mentioned steps
1. Restart System
2. You will see operating system choices, press F8
3. From Windows Advanced option Menu bar Choose "Last Known Good Configuration". (issue will get resolved if bluescreen 0x000000d1 error occurred due to single driver or service)
Solution 5: Check Antivirus
If the issue is due to some other reasons such as some antivirus, corrupted database registry, Hardware
Antivirus- Do a through Antivirus check, if it does not work, then keep it close for some time then once the issue gets resolved then activate antivirus again.
Clean RAM- Remove Extra Ram by Restarting the system
Run prefetch and clean manager by visiting Start menu> type run> type prefetch or type cleanmgr.
Some System File drivers
Srv.sys is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices. This means that a driver has direct access to the internals of the operating system, hardware etc.
A clean and tidy computer is the key requirement for avoiding problems with srv.
This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
