I am attempting to decode and resolve this issue.
My GPU is seated correctly and although I am almost positive that it is not a heat issue I do have an additional large fan blowing on it at the moment.
How did you determine that the error is a 0x116 or 0x117?
I think that it is a 124 error but I am not familiar with this type of analysis and it seems that you are.
I am also interested in how you determined that the drivers you mentioned (nortan & Sai Tek) are not up to date and I believe that you are most likely correct in terms of these being out of date.
Thanks again for your assistance and I look forward to hearing back from you.
