Crashes And Various Glitches / Artifacting After Direct X Update

my problem started after running the following dxsetup.exe, which was required to play a mod for the game morrowind (apparently some files were missing from the most recent versions of dx): (url) everything seemed to work fine after this. i played the mod for a while, then yesterday i decided to buy deus ex: human revolution. again, i installed, the game required a dx update which processed fine, and i played the game for a few hours and went to sleep. the next day, my problems began. i noticed Internet, livestream, own3d.tv, or any web video player would crash after a minute or so. the video would stop, the sound would stutter and distort, and i get a brief black screen and a then the video player restores with a green screen instead of the video playing, and in my task menu a pop up occurs with "nvidia kernel 180.26 has crashed and successfully recovered"
