If you recently installed new hardware, try disabling it to see if it resolves the issue. Go to Device Manager, find the newly installed device, right-click it, and select Disable device. If disabling the device fixes the error, you may need to contact the hardware manufacturer for an updated driver or further assistance.
Method 4: Perform a System Restore Show Steps ↓
If the issue started after a recent software installation or system change, try performing a system restore to a point before the error occurred.
