Explorer.exe System call failed is one of the troublesome Windows niggles that can render your system virtually useless.
Before the error message is flashed on the screen, the icons disappear and when the user clicks on the Start button the Explorer.exe System call failed error is displayed.
Needless to say, one would mistake it to be a malware or a virus attack but in reality its none. Neither is it a case of Windows operating system gone bad.
Before we start with the actual troubleshooting, lets take some time to perform some basic checks. Try recalling whether you had done any changes to the system.
Also, try switching your account and see if its the same error persists. Try restarting the computer.
As observed in forums this error is usually suspected to be caused by drive errors. Bad sectors in your Primary hard disk will cause severe performance issues.
One can also try connecting an external drive and see it it’s being read.
Here’s how to solve System call failed error on Explorer.exe
1) Clean Boot
Since none of the software is opened automatically in the background the Clean Boot will let you avoid the software conflicts.
- Go to start, search for msconfig
- Select System Configuration from the results
- Click on the Checkbox that says Hide all Microsoft Services (In case of Windows 10 CU select Diagnostic Startup)
- Go to the Startup tab in the System Configuration and click on Open Task Manager
- Select the programs individually and then click on Disable
- Close the Task Manager and restart the computer
2) Alternate method
Now in this step, you can troubleshoot each drive for errors and you can also check the computer’s primary hard disk for performance issues.
Also, consider comparing the same with the external hard disk.
- Open the Windows File System
- Right Click on the desired drive and then select Properties
- Now go to the Tools tab>Error-Checking>Check now. Type in your admin credentials if asked for
- Ensure that you check the Automatically fix file system errors so that the system will not only check the drive for disk error, but will also fix the issues if any
- In order to perform a deep scan, select Scan for and then attempt the recovery of bad sectors. In this mode, the scan will attempt to fix the physical errors and will take longer to complete the task.
- Select Automatically fix file system errors and Scan if you prefer checking both file errors and physical errors. That being said if any bad sectors are found on the hardisk the data will be lost.
Also, you can try out the EaseUS software which promises to fix your hard disk without causing any loss of data.
