Bad Pool Caller Error – How to Fix the Bad Pool Caller Blue Screen Error on Windows

The “BAD POOL CALLER” error is actually one of the most damaging errors known to Windows users – as it’s renowned for restarting your PC and showing a fatal “blue screen of death”. Many people receive this error but don’t even know what causes it. This means that if you want to repair this problem, you first need to know why it shows and then how to fix the various parts of your computer that often cause it. Here’s what you need to do…

This Bad Pool Caller error is actually shown because of your PC’s “data pool”. The data pool is a small collection of files & settings which Windows computers use to help them call various settings instantly on your system. It’s like having a small pool of information that your computer can “dip into” in order to quickly gain settings / information about your PC. Not many people even know the data pool exists, but the fact is that it’s continually causing errors which often include the “BAD POOL CALLER”. This particular error is caused when your system tries to “call” / “load” a certain setting from the data pool, but finds it cannot. This sends your computer into a blue-screen crash, making it unable to proceed.

There are various reasons why this error will show, and to be honest, no-one really has a set checklist of exactly what causes it. The best thing to do is to first check the “hardware” of your PC is functioning correctly, then that your programs are working well, and that Windows is running as smoothly as possible.

The initial step you must take to repair this problem is to ensure the hardware of your PC is working well. To do this, you should do this by checking all the cables and connections that your various hardware components require, are all secure and working. This can be done by just looking at the various parts of your computer and taking a mental note to see if everything’s okay.

After that, you should then look to reinstall any program which could trigger this error. It’s often the case that resource-intensive programs, such as “Photoshop”, will often call so many data-pool components that it will trigger this error. To ensure this is not a problem, you should reinstall any programs which trigger the issue.

Finally, and this is probably the most effective way to fix the Bad Pool Caller error, you should look to repair any issues that are inside the “registry” database of your PC. The registry database is a central storage facility which keeps all the files, settings & options that Windows requires to run each day. Unfortunately, this database is used so much by your system that it’s continually being damaged, leading your computer to become unable to read the files it needs to run. To ensure this is not causing the bad pool caller problem, you should look to clean out the registry by using a “registry cleaner” application.

Error 37 – "Windows Cannot Initialize the Device Driver" Fix

Error code 37 on Windows is what’s known as a “driver error” on your computer, and is caused because your hardware is damaged or the drivers on your system are corrupt. If you are seeing this error on your PC, it suggests that there are is something wrong with the way your computer is interacting with your hardware, and needs to be fixed.

This error will often show in this format:

  • “Windows cannot initialize the device driver for this hardware. (Code 37)”

The error you’re seeing is actually caused by the way in which your computer handles the hardware on your system. Every piece of hardware that your system uses has to be controlled & accessed by using a piece of software called a “driver”. These software components basically allow your system to interact properly with all the hardware of your PC, and are therefore amongst the most important parts of your Windows system. If you’re seeing this error, it generally means that there is some sort of issue with the drivers of your computer – with them either being not installed correctly, or damaged and unreadable. 

The way to resolve this error is actually quite straightforward. The first step is to update any drivers which are damaged. This can be done by following the steps here:

  • Click Start > Control Panel > Device Manager
  • Upon loading Device Manager, locate the hardware component with the “Yellow Exclamation Mark” icon by it
  • Right-click this device and then press “Uninstall”
  • This will remove the hardware from Windows
  • Momentarily, your PC will say it has found new hardware – let it install any new drivers it needs to run this hardware
  • This should resolve most cases of the 37 error code

Performing the steps above will basically “reinstall” or “update” the driver on your system. It’s often the case that a hardware driver will either become damaged, corrupted or just unreliable – making it essential that you’re able to get Windows to update any of the issues it may have with it. 

You should also clean out the “Registry” of your computer by using a registry cleaner tool. Registry cleaners are software programs that are designed to scan through the registry database of your computer and fix any of the problematic files that are inside. The registry database is essentially a central storage facility which allows Windows to recall a huge number of different options, from your desktop wallpaper settings to your most recent emails. The registry is a major player in the installation of drivers & hardware on your system, and if you have any damaged elements inside it, the likelihood is that your computer will become damaged and erroneous as a result. You should use a registry cleaner to make sure that no further problems are causing the errors to show on your system, which can be done by downloading one of these tools from the Internet, installing it and then letting it fix any possible problems on your PC.

Slow System Performance – How To Fix It?

Slow system performance is one common issue that most computers face. Due to the nature of their operation, PC’s tend to lose their efficiency over time. However, it is mostly not because of the failure of the hardware, but due to the so-called “mess” inside the software parts of the computer. In order to fix this problem, some areas of the pc need special treatment.

1. Fragmented files

The first cause of slow system performance is the fragmentation of files. In other words, the information on the hard disk becomes disorganized. And when a program or application loads, it takes more time. All the files that are needed for the operation of this program, are now stored in various parts of the hard drive, instead of being in the same sector of the disk.

This problem is a natural result of everyday computer usage. During the operation of a PC, certain files are deleted and others added. This slowly fragments the data. One of the best cures for cleaning up such chaotic placement of data, is the Disk Defragmenter. It is a free tool that all windows-based computers come with.

2. Windows Registry

Slow system performance can also be caused by the “mess” inside the Windows registry. This delicate database stores key attributes and settings of most programs and applications. Since windows accesses registry files regularly, slight modifications are constantly made.

In addition to the fragmentation process of the hard-drive, registry is slowly filled with old entries which are no more valid. Such outdated registry entries can cause slowdown, errors and even system crashes.

It is advisable to run a registry cleaner, which can restore the registry to its healthy state. This software scans and deletes all invalid entries.

3. Virus

Finally, slow system performance may be a symptom of a malware or a virus. These type of dishonest programs can often run quietly in the background, eating up system’s resources and paralyzing the smooth operation of the computer.

Hence it is vital to select a reputable anti-virus software, which is capable of detecting and eliminating such threats from the computer. After installing the software, make sure you also download any updates available for this program. This ensures that your copy of the program is equipped with the latest virus definition files. Otherwise the anti-virus software may not be capable of recognizing the newest threats.

To fix slow system performance, run the Disk Defragmenter to eliminate the fragmentation of files, perform a scan with the registry cleaner software to keep the registry well-organized, and use an anti-virus software with its latest virus definitions to keep your computer free from malicious software.
