welcome to bitcoin, the more the merrier

"excuse my buttcoin"

i got this answer on another forum that i posted on and this worked great for any of you that come across this problem in the future:

"try older drivers. IIRC AMD dropped WinXP support in OpenCL support with AMD APP 2.7.  catalyst 11.2-11.4 should be last one which have proper opencl support at WinXP"

welcome to the forum.  i am going offgrid bitcoin mining!

I have a HD5830 Video card working fine in my computer but when I load GUIMiner it says: No OpenCL devices found.  I searched google and the forum and found a previous thread that said to try and re-install the ati drivers but that didn't work.  I also tried installing the ATI Stream SDK but that had a warning about not finding GPU as well.  Anyone with anything I could try to get mining?
