Hello Ahjpeace, you may want to try installing the latest Graphics driver available Version 3945.
Intel® Iris™ and HD Graphics Driver for Windows* 7/8/8.1 32bit
Intel® Iris™ and HD Graphics Driver for Windows* 7/8/8.1 64bit
Bear in mind that we provided generic drivers; therefore sometimes these cannot be installed on OEM systems or the installation of them could overwrite OEMs customizations and possibly change the functionality of the graphics.
I would recommend using only the system manufacture drivers, however, if you are still want to install our drivers, you may try forcing the installation by performing manual procedure, however I cannot assure you they are going to work as expected.
