Scan your computer with an anti-virus program

The Bad Pool Caller error occurs when Windows encounters a problem while trying to allocate memory for something else. This usually happens because you’re running out of space on your hard disk. If you’ve been experiencing problems with your PC recently, it might be worth having a look around your hard drive to make sure nothing is causing you grief.

If you suspect that malware or viruses have infected your machine, run an anti-malware program like Microsoft Security Essentials, Kaspersky Internet Security or Panda Cloud Antivirus. These programs will check your PC for malicious software and help you identify what’s causing the errors.

Restart your computer

A reboot might seem like overkill, but it’s one of the best ways to solve most computer problems. If you’re having trouble getting your PC to boot up properly, here are some things to try.

1. Check your power supply. Make sure there isn’t too much dust inside, and that the fan blades aren’t blocked. Also make sure that the cables connecting the motherboard to the power supply don’t look frayed or loose.

2. Try turning off unnecessary hardware components. For example, if you have a webcam attached to your PC, turn it off. You don’t want it running while you’re trying to troubleshoot.

3. Reset your BIOS settings. This is done by pressing F12 during startup. Sometimes Windows will automatically reset the BIOS settings, but sometimes you’ll have to do it manually.

4. Remove any external devices such as USB drives. They could be causing conflicts with your system.

5. Delete your browser cache. When you close down your web browser, it saves information about what you’ve been doing online. Deleting the cache allows your computer to start again without retaining this data.

Uninstall any software or hardware you recently installed

The Bad Pool Caller 0x00000119 error often occurs due to newly installed hardware or software. Here we recommend you uninstall them one by one to check whether the problem still exists.
