Published by Nyau Wai Hoe - Updated on

Some folks who use an AMD graphics card on Windows 11 or 10 have bumped into an error message when they start their computer, just before they log in. The message usually says “AMDRSServ.exe – System Error” and goes on to explain: “The code execution cannot proceed because OpenCL.dll was not found. Reinstalling the program may fix this issue.”

Although this might seem a bit scary, it’s not the end of the world. Your computer should still work fine, but you’ll keep seeing this message every time you turn on your system. The good news? There’s a way to fix it. We’re here to walk you through what causes this annoyance and how you can make it go away.

AMDRSServ.exe System Error OpenCL.dll Was Not Found

What could cause the AMDRSServ.exe system error?

Let’s first understand why you’re seeing this error. At the heart of the problem is AMDRSServ.exe, which is a key part of the AMD Radeon software. This program handles a lot of the graphics stuff on computers with AMD hardware.

The OpenCL.dll file is a piece of the Open Computing Language (OpenCL) framework, which helps your computer do complex tasks faster by using the graphics card and the processor together. It’s pretty important, so if there are any issues with this DLL file, it can mess up several AMD-related operations on your computer.

What is AMDRSServ.exe and OpenCL.dll

Corrupt or missing OpenCL.dll file

The error usually pops up because the OpenCL.dll file is missing or damaged. This could happen if:

  • The AMD graphic drivers didn’t install properly.
  • Some other software accidentally deleted or replaced the DLL file.
  • Malware or viruses messed with your system files.

Outdated drivers

Old graphics drivers can also cause trouble. As new software comes out, your drivers need to keep up. If they don’t, they might not work well with newer versions of OpenCL, leading to errors.

Software conflicts

Sometimes, other programs, especially ones that work with graphics, might mess with AMD’s stuff. This can make it hard for your system to find or use the OpenCL.dll file.
