The most common causes are bad or outdated drivers—especially for network, graphics, or antivirus—trying to use memory the wrong way.Other possible reasons are broken RAM, software conflicts, or damaged system files like klwtp.sys. In this article, we will discuss different ways to solve this error.
Boot Windows in Safe Mode (If Needed)
This method is for users who are stuck in a restart loop or whose Windows isn’t starting properly, even after a forced shutdown. Since you can’t use Windows normally, you’ll need to boot into Safe Mode. Safe Mode starts Windows with only essential drivers, services, and programs. If you can’t boot into Safe Mode, or if you still face the BSOD even in Safe Mode, your Windows installation might be corrupted, or there could be a hardware problem. In either case, you will likely need to perform a clean installation of Windows.
1. Clean Installation of Graphics Driver
A corrupted graphics driver is a common cause of the BAD_POOL_CALLER BSOD. Doing a clean installation removes the current driver and reinstalls a fresh copy. If your computer won’t start normally, first boot into Safe Mode using the steps above. If the error appears randomly, proceed with these steps:
2. Uninstall Problematic Drivers
The “WhoCrashed” tool can analyze system crash dump files and help identify the driver causing the problem.
3. Update Component Drivers
Outdated or corrupted drivers for components like sound cards, network adapters, or USB devices can also trigger the BSOD. You can easily check and update these drivers:
4. Uninstall Third-Party Antivirus Software
Third-party antivirus programs can sometimes interfere with essential Windows drivers and services, leading to conflicts and causing your system to crash. To rule this out, uninstall any third-party antivirus software:
5. Disable Overclocking
If you use any overclocking software on your system—for your graphics card, CPU, or RAM—overclocking can sometimes push hardware past safe limits, causing instability and BSOD errors. To fix this, either reset your overclock settings or uninstall the overclocking program.
6. Use System Restore
If you’re still experiencing problems, restoring your computer to an earlier point when things were working fine can help. System Restore is usually already turned on by default, or some third-party programs create restore points before making changes. We’ve covered all the main solutions above to help you fix this issue. However, if none of the methods work, there may be a hardware problem with your system. You can confirm this by reinstalling or resetting Windows.
