Have Radeon HD 7850 from Sapphire installed in MSI board and attached, with an adapter, to an Acer monitor. had zero issues until I updated to the newest Crimson driver. Worked for the most part but would cause an occasional out of range error. Dropped the refresh rate to 75 from 85 and had the out of range error all the time. Had to remove video card and drop in another just to access my computer. Have uninstalled all AMD software but would like to reinsert my video card without the issues. any suggestions?
