Download Dell Optiplex 755 Windows 7 Drivers

Here are the two downloads needed for the missing drivers for the optiplex 755. I thought I would share since these were so difficult to locate.

I hope this helps some others.

Fixed – Resolved – FATAL kernel error: Failed to load OpenCL kernel!

If your getting this like I did you problem just updated your ATI drivers to the latest version.

FATAL kernel error: Failed to load OpenCL kernel!

I was running windows xp.

Go to start>>settings>>control Panel>>>add/remove programs.

Remove anything related to ATI.

Then install the old drivers. You can download the ones I used for my ATI Radeon HD 5700 series here:
