Some blue screen errors are easy to handle and others are very difficult to handle as they do not allow users to boot the system. One such case is with:
CLASSPNP.SYS blue screen in Windows 10
Causes of this error include corrupted files on the system, interfering hardware, damaged drivers, and problems with the BIOS.
Since the blue screen error usually occurs shortly after Windows 10 loads, we should fix the problem in Safe Mode with Networking. This is the procedure for starting the system in safe mode.
Try the following solutions one by one to fix the problem:
1} SFC scan
2} Update the device drivers
3} Update the system BIOS
4} Check for hardware damage
5} Disconnect the hardware devices
Solution 1] SFC scan
The SFC scan helps to repair damaged or missing files in the system. This is the procedure for an SFC scan.
1. close cmd in Windows 10 search.
2. Right-click and run as administrator.
3. Now copy and paste the command given below.
SFC / SCANNOW
4. Press the Enter key. Wait a while for it to work completely.
Solution 2] Update the device drivers
Usually all drivers are updated every time we update Windows. This is the procedure for updating Windows. However, as we are isolating possible causes, we should update each driver one by one. The procedure for updating the drivers is as follows:
1] Press Win + R to open the Run window. Enter the devmgmt.msc command to open Device Manager.
2] Right click and update ALL drivers one by one.
If this procedure seems difficult, you can use any of the third-party tools available online to help you.
Solution 3] Update the system BIOS
1] Press Win + R to open the Run window. Write the command msinfo32 and press Enter to open the System Information window.
2] In the right pane, check the BIOS version, date and manufacturer.
3] Go to the manufacturer's website and download the latest version of BiOS. You can also Google the BIOS name and version to find the download.
4] Download the latest BiOS file and install it. Restart the system.
Solution 4] Check for hardware damage
1] Open File Explorer and go to This PC.
2] Right click on the system drive (C: in my case) and select Properties.
3] Go to the Tools tab and click Verify. You would need admin permissions.
4] Click the Drive Scan option and let it scan your system drive.
5] Reboot the system once done.
Solution 5] Disconnect the hardware peripherals
One of the causes of this problem is the hardware problem. Since we have already updated all the drivers, the cause of the corrupt drivers has been isolated. You may now need to completely remove the problematic hardware.
1] Disconnect all peripherals except necessary ones such as keyboard, mouse, etc.
2] Boot the system in normal mode.
3] Try to reconnect the peripherals one by one and see what the problem is.
4] Defective hardware may need to be permanently removed or replaced.
