Solve ialmdev5.dll Blue Screen of Death Error

The file ialmdev5.dll is part of the driver set for your motherboard chipset. When you start your Windows computer or try to launch Sim3—a strategic life simulation computer game developed by Sims Studio and published by Electronic Arts—you may encounter a Blue Screen of Death (BSOD) error. An error message similar to the one below may appear:

  • “A problem has occurred and Windows has shut down to prevent damage to your computer. The problem has occurred with ialmdev5.dll. This could be caused by new software you have installed.”


Generally, the above error is reported when a conflict occurs between the video drivers installed on your computer and the program that uses the ialmdev5.dll file. Malware infections too can cause BSOD errors such as the ones shown above.


The first thing you need to do when you receive a DLL error is to run a malware scan on your entire computer. A malware infection can cause all kinds of problems, included annoying DLL errors. Only after you have ruled out a malware infection should you try other things to resolve DLL errors.

If you are able to launch Windows in Normal Mode, then do so and use your antimalware software to run a malware scan. Otherwise, launch Windows in Safe Mode (by pressing the F8 key as Window loads) and then perform a malware scan.

If the malware scan reports no infection or the error occurs even after you have quarantined or deleted the reported threats, perform the following steps to fix the error.

  • Download the latest Intel video driver from the Intel website
  • Save the driver file on your desktop
  • Uninstall your current Intel video driver
  • Install the latest Intel video driver

One thing you need to keep in mind is that you must download the latest Intel video driver only from Intel’s official website. Although you may be able to locate the driver you need on other websites, it is better that you don’t download files, as well as software, from unknown websites. The reason is simple: many websites are known to push malicious programs disguised as genuine files or software. Installing malware-laced software or rogue files may cause serious damage to your computer and put your confidential data at risk.
