This could mean a lot of things. You need to provide more information. Detail hardware (board, processor, memory, add-in cards, drives, USB devices, etc. and etc.), software (i.e. What version of BIOS is installed? What O/S is installed?) and driver configuration (i.e. What are you using to update drivers (Intel Driver Update utility or discrete driver packages)? What drivers did you install before attempting to install the one that failed? Did you reboot just before attempting to install this driver? Detail anything else you think might be relevant.
