A Guide to the “Bad Pool Caller” Blue Screen of Death Error

Sometimes, your computer decides to give a terrible wailing noise and fill your eyes with a much-feared Blue Screen of Death, though on newer computers its forms are much friendlier. With the bad_pool_caller error, your BSoD should look like this:

BAD_POOL_CALLER in Windows 7.

Or this:

BAD_POOL_CALLER in Windows 8.

Despite the name, Blue Screens of Death usually don’t have such dire implications as the name given. BSoDs happen whenever your computer is encountered with something it doesn’t know how to process, so it shuts itself down to prevent any damage. Sometimes BSoDs just happen once and you don’t see them again when you restart — however, this solution isn’t always reliable, and whatever’s causing your problem is so persistent that the BSoD is striking repeatedly.

In the case of bad_pool_caller, what has happened is that a thread in your processor has made a bad pool request. This means that it’s asking to use resources that are unavailable, nonexistent, or in use by another thread. It could also mean that the pool header is corrupted — regardless of the particular error, it, like most BSoDs, is caused by driver issues.

Drivers are, in short, what makes your computer work. Every device connected to your computer — and nearly every component inside it — has a driver that determines how it interacts with your device. Thanks to a good driver, your mouse clicks are registered. When driver issues are encountered- which is fairly common on new operating systems like Windows 8 — it can cause a lot of problems for the computer and the end user, but, fortunately, there’s usually an easy fix.

If you can determine what device has started to cause this error — normally a new peripheral — go to Device Manager (in the Control Panel) and find your driver. From there, you can get Windows to search for updates, you can disable it, or you can uninstall it entirely. You can also use our Driver Reviver software, which is automated, to find the driver issues inside your computer and fix them all, which should help you significantly in the future.

If your Drivers aren’t the problem, however, a new program may be the issue. If you can determine what program you installed that started this, uninstall it and, after a restart, you should be good to go.

Any further issues are best taken to Microsoft or your manufacturer’s tech support. If you’re using Windows 8, however, be sure to update your BIOS and drivers completely before taking these steps. Due to its stance as a new operating system, it isn’t as well-tested as most are. Instructions on updating your BIOS can be found on your manufacturer’s website, or at the article linked above.

  • It may be a newer driver causing the error. Try rolling back you graphics driver to see if that fixes the problem.

    I have this issue because of the uninstalling ESET SMART SECURITY… and so i did not find any solve..(

  • So you started seeing the issue after uninstalling ESET? Does it go away when you install ESET again?

  • Kamran Güneş

    No It does not. After that i have tried to install again or reinstall but always had the blue dead screen. So I have tried to restore system but cannot restore either. I think the problem here is the Windows Installer. Because the installer is not working too after the ESET.

  • What installer is not working? What are you trying to install?

  • Kamran Güneş

    “Windows Installer” as I say is not work and you cannot install or reinstall any program after you have the bad_pool_caller so I check some drivers and no I can not find any solution yet!

  • Daniel Wassenaar

    I got this error when I set up a wifi hotspot with my desktop. Very odd but it only ever happens when I do that. I guess I’ll just stop from now on.

    “..go to Device Manager (in the Control Panel) and find your driver. From there, you can get Windows to search for updates,..” WTF?? BSOD means NO windows…

  • Zac J

    Sometimes it happens when you overload the ram so fast that the PC doesn’t know what to do and shuts itself down happens a lot on old compiter. Other than that 90% of the time it’s because you have bad ram or windows itself is corrupted

  • Flare

    Why is it called the ‘Screen of death’?

    I got this bad pool caller after installing a firewall if that’s an indication that the fire wall is shutting down some critical software from running.

    Driver Booster from IoBit software is free.

  • Ric Euteneuer

    It is indeed Pyxelmajick – I was talking about Driver Reviver, not Driver Booster

  • Pyxelmajick

    my antivirus doesn’t like driver reviver…sorry!

    This happened on one computer. There were no new devices on the computer. However, this bad pool error started after I selected and copied some text from an article to the clipboard.. Just after that, the website covered the text with a dialog box telling me I had to log in to use the site. When I pasted the text into Word and saved it I got the Bad Pool Error blue screen.

    This error then spread to all USB drives on that computer. It happens only only when a Microsoft Office product saves to a USB drive.

    The problem was still there after reinstalling Windows XP and Office 2007. I then took a flash drive containing the files I was working on to another computer running XP and Office 2010. This problem spread to that computer, again affecting all USB drives.

    Could that website have somehow infected that text and caused it to make the computers fail?

  • Midimagic

    This is caused by Microsoft Office. After a Microsoft update, it changed so it no longer can save a file to a flash drive. It must save the file to an actual hard disk.

  • Midimagic

    Actually I found out that this is caused by Microsoft Office and happens only when Office files are being saved. After a Microsoft update, something changed so it no longer can save a file directly to a flash drive. It must save the file
    to an actual hard disk.

    A copy of the file can then be moved or copied to a flash drive, and Office can read the file. But it can’t save that file, edited or not, to the flash drive.

    So, the problem could be anything!… Ok, so, I could’ve written the article, and just say: “the problem can be anything, check software, hardware, everything…” Excuse me, but are you joking?!…

    i am running windows 10 and im getting the blue screen, only when I torrent.

    You’re kidding no one here.

    My Dell Vostro 410 from 2008 had been suffering this problem. I just switched out the RAM, processor, GPU, and 2TB HDD from my Inspiron 530. Whenever I booted it, it would give me this error screen, even if I tried to boot it in Safe Mode. And it would ALSO do it if I tried to launch Startup Repair. Apparently, the RAM cards were switched around on the wrong sides. Thanks for the info!
