2. How to fix the error BAD_POOL_HEADER

Step 1: Press the Windows + S key combination. Then find and open the devmgmt.msc or Device Manager software .

Step 2: Identify the driver that is likely to cause the error. Right click on them and choose 1 of 3 actions :
- Update driver : Update new version.
- Disable device : Disable temporarily.
- Uninstall device : Uninstall this driver completely.

- This driver check method is extremely effective if you have just installed a certain driver and immediately the computer has BSOD. In this case, please remove the driver and reinstall it, if it still persists, the driver is not compatible with your computer and should find another driver to replace it or contact the hardware manufacturer for support.

+ Downgrading from a higher Windows version to a lower Windows version, for example from Win 8 down to Win 7

If so, see below, if not, the error lies in the hardware or its driver. In this case, please review the driver update section of the BAD_POOL_HEADER error code above.

Step 1: Press Windows + R key combination => Enter msconfig =>  OK .

Step 2: In the General tab select Selective Startup and uncheck the box Load startup items .

Step 3: Switch to the Service tab , select Hide all Microsoft services .

Step 4: On the screen now only the services of the third-party app and driver remain . Click Disable all and OK to boot the machine into clean boot .
