Have you run Windows Update and installed the relevant 'optional' and 'recommended' updates ? These are important and will not be downloaded automatically. Can you see any updates that have to do with graphics that Windows Update has recently installed? If so delete them. Did the drivers from Samsung include the drivers for the Intel graphics as well as the AMD graphics?
EDIT: Also Google ' error code 43 ' as there is some good information there.
