When a computer displays a BAD_POOL_HEADER warning, and if simply restarting the computer does not fix the problem, then the entire Windows system should be refreshed under the "repair your computer" option after inserting Windows bootable media into the CD drive. If the problem is not solved after reinstalling Windows, then the computer might be damaged beyond repair.
The BAD_POOL_HEADER error indicates that there is an issue with the computer's physical memory. If the RAM or a disk drive is not functioning properly, there are certain built-in ways to fix the problem within the Windows software. Sometimes the BAD_POOL_HEADER error can be fixed by rebooting the computer. Upon startup, the memory system could have experienced a rare bug that stopped it from performing its task. If the error continues following a reboot, then try the following steps:
- Insert Windows bootable media into the CD drive
- Navigate to the "Refresh your PC" screen
- Refresh the Windows software
Insert the Windows installation CD into the disk drive and restart the computer.
Click "next" on the "Windows Setup" screen. Then, go from "Repair Your Computer" to "Choose an Option" to "Troubleshoot." From here, click on "Refresh your PC."
Click "next", and on the "choose a target operating system" menu choose the current Windows operating system. Click "refresh" and wait for the entire system to refresh and the computer to reboot.
