System Service Exception Atikmdag.sys: Quick Fixes

Keelan Balderson

When you get a System Service Exception atikmdag.sys error it leads straight to your PC getting a Blue Screen of Death (BSOD) and rebooting. This error is typically related to graphics drivers or system file issues, but there can be many underlying problems to solve. Here’s how I fixed my own system and all the ways you can quickly fix yours. But firstly, what causes this error?

What causes the System Service Exception Atikmdag.sys error?

An outdated AMD driver and a bunch of corrupt system files were the main problem I faced when getting a System Service Exception Atikmdag.sys error. After doing further research, here’s more about why that happens and other related problems:

  • Corrupted System Files: Damaged or missing system files caused by malware, hardware failure, or software conflicts, among other reasons. Running built-in system scans helped me identify and fix these issues.
  • Faulty Graphics Card: When trying to run an old, faulty, or incompatible AMD graphics card. Replacing or upgrading your system will fix it.
  • Conflicting Applications: Some third-party software like overclocking tools or bad system tuners can interfere with your graphics card and its drivers. Uninstalling these applications may help resolve the issue.
  • Windows Updates Gone Wrong: Sometimes, a Windows update may fail to install correctly, contains bugs, or is incompatible with older harder, leading to the atikmdag.sys error. Reinstalling the updates or rolling back can fix this.
  • Overheating Issues: I realized that my computer was overheating, and it was causing corruption and other errors, including the atikmdag.sys BSoD. Reapply thermal paste to my heatsink fixed this problem, but you should also check for dust build-up or faulty fans.
  • Corrupted Graphics Card Drivers: I found that not just outdated, but corrupted graphics card drivers could also lead to this error. Removing the drivers completely and starting fresh is the best solution.
  • Hardware Issues: Problems with other hardware, such as incompatible or failing RAM sticks, can have knock-on effect on your GPU. Running hardware diagnostics can help identify and fix these issues.
