so i have a AMD A8-3500M APU with Radeon(tm) HD Graphics 1.50 GHz, and i try open up AMD vision engine control center program and it says my graphics driver is either not installed or corrupt, i checked for updates and its all the way updated and it says it is functioning fine, but i can tell it isnt running as good as it usually does. i lag a lot in games i never lagged in. I can get the card to install perfectly fine off of the website, but the minute i turn off my laptop it uninstalls again. someone help.
