Dell OptiPlex 790 Desktop 285MM HDD SATA Data Cable - 0M62D. Buy it for $1.95 Get it by Saturday Aug. 11th if you order now & choose one-day shipping. Only 1 left in stock - order soon. Sounds like you did a lot to troubleshoot this. I ran into interesting issues with Optiplex 790 and also 9020 where some Intel display drivers from Windows update are coupled with audio functionality (I guess to power some built in audio features in displays). Also does the 790 have any expansion cards for video or other media attached?
