How To Fix The Bad_Pool_Caller Error

Reader Question:
“Hi Wally, This blue screen bsod “ bad_pool_caller ” has appeared twice since the last two hours. I’ve already scanned my computer for malware and viruses. Please Help. Thanks in advance.“ - Kimberly K., Australia

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Blue screen errors sneak up on people. These errors are not welcomed by anyone but they are pretty much inevitable. Computers are not perfect machines and there is no perfect software either. These blue-screen errors occur when the computer encounters something it can’t handle.

Luckily if you know the error code of the blue screen error, then you should be able to correct it yourself.


The Bad_Pool_Caller error appears and the computer crashes.

Bad_Pool_Caller - Cover - BsOD -- Windows Wally


The Bad_Pool_Caller blue screen error occurs when the processor makes a bad pool request. This is caused by corrupt device driver software.


Here are some ways to fix the Bad_Pool_Caller error:

Device Drivers Related Problems

A device driver is a software that sits between the computer’s hardware and the computer’s software. It helps them communicate with each other. Device drivers pretty much help the computer function. This error occurs because a driver communicated incorrectly.

To fix this problem, you can try figuring out which driver caused this problem. Thought that can get a bit technical. Instead, you can also disconnect a recently used device if the problem started since you started using that new device. If it was software then try removing the software from your computer.

Update Device Drivers

You can also update all device drivers to fix the problem. This makes them much less likely to run into problems.  You can do this by going to your computer manufacturer’s website and searching for your computer. Once you have found your computer on the website, start downloading all the drivers, and installing them one-by-one.

If installing drivers manually doesn’t suit your mood then don’t worry. There exist alternatives like the DriverDoc driver utility. This software program searches online for available driver updates and downloads a suitable driver based on your operating system and the current driver version you have installed on the computer. DriverDoc helps you install these drivers in case you are short on time.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
