This past weekend windows updater forced me to upgrade to 8.1. After the download i have been unable to play any of my favorite games due to the dreaded blue screen of death. I did a windows checkup and found that my problem was with my Graphics card. I did not have the drivers installed correctly. 
As i continued to work i was able to find the most current drivers for my graphics card but when i tried to install it i kept getting the same error message. 
Please. If anyone can help me out i would greatly appreciate it.
