Stop code MACHINE CHECK EXCEPTION on the blue screen in Windows 11 is associated with hardware problems like an excessive load on the processor, video card or RAM. In addition, faulty drivers can cause a crash, or the latest update has disrupted the operation of components of the computer or laptop. This tutorial is about removing BSOD stop code MACHINE_CHECK_EXCEPTION in Windows 11.


1. Remove all USB devices

If you have various USB devices connected to your PC, such as a printer, flash drives, or a scanner, remove them and reboot the system.

2. Update drivers

Press Win + X and select ” Device Manager “. If you have devices with a yellow exclamation mark, there are driver problems. Right-click and select Update Driver Software. If it does not help, then ” Remove device ” and reboot the system.

Alternatively, click on the ” View ” tab and select ” Show hidden devices .” Next, expand the list of all device items, delete everything that has a translucent look, and restart the PC. These are old unnecessary drivers and those devices that are currently disabled and do not work.

3. Update Windows

Go to the Windows Update section and update the system to the latest version; this may also update the latest drivers.

4. Sectors on disk and SYS files

The error code may appear because a bad sector on the disk does not allow the loading of the necessary files, and a load is created on this disk, causing the MACHINE CHECK EXCEPTION error. Also, damaged system files can cause this BSOD. We will check and automatically fix bad sectors and system files, if any.

Run Command Prompt as administrator and enter the below commands in order, waiting for each process to finish:

  • chkdsk /f /r
  • sfc /scannow
  • DISM /Online /Cleanup-Image /RestoreHealth

5. RAM diagnostics

Press Win + R ( or on the command line ) and write mdsched.exe to invoke RAM diagnostics and repair. Follow the recommendations on the screen, and after a reboot, a RAM check will run for errors.
