BAD – By mentioning the word “Bad”, your computer is just saying that there is something, which is causing discomfort to the pool header. POOL – We normally just don’t say “pool”, it’s having a full name called “Memory pool” which is mainly created by the memory manager in your system to use the allocate memory. These memory pools are divided into two parts and the first one is “Non-Paged Pool” and the second one is “Paged Pool”, both are located in the region of the address space that is reserved for the system and mapped into the virtual address space of each process.

You’ll just need to press F8 key again and again on your computer’s startup until you’ve got your screen looks like the picture given below, select safe mode in those options to open it. If you’re using Windows 10 then press Shift key 5 times again and again on startup. This “Bad Pool” problem is mostly occurring in windows 10 and Windows 8 because we did install or update our windows without checking the software and hardware compatibility and that’s why this problem starts to showing up on our screen. So if you’ve recently installed Windows 10 or 8 then I highly recommend you to update all your software and drivers to the latest version. Let’s talk about how to fix this error on any Windows: Now the first thing is, I want you to remove or uninstall all Security Softwares from your Windows besides the Firewall. By saying Security Software’s I means you’re “Antivirus Program” or maybe some “Malware And Root-kits Removal Tool” whatever you’re using, just uninstall it. For those who are using Malwarebytes software, just uninstall it because lots of people solved their problem by just removing it. So, if removing anything from your computer won’t works for you then, you can install everything back. 1# Recent Changes and Remove USB Just undo all the recent things what you’ve done to your computer because it’s possible this problem is coming from that. So, remove or disconnect any hardware what you’ve attached recently, like new ram or something or if you’ve installed something recently than uninstall that software too, whatever you’ve installed. If uninstalling or disconnecting won’t works for you or maybe you don’t do anything recently then you can also try to remove everything attached to your USB slots because sometimes our computer’s operating system does getting some problem to install or operate external USB device’s drivers and creating this BAD_POOL_CALLER error. So, the simple solution is to remove all external USB connected devices from your desktop’s or laptop’s beside USB keyboard and mouse and restart your computer after that. When restart gets done, just try to use your computer and test it and see did you still getting this problem or not, if yes then move to next solution. 2# Repairing Drivers Or Windows 80% you’ll fix your computer by doing this step; normally this problem did occur because of corrupted drivers, corrupted registry, viruses and something those kinds of stuff.
