I have an AMD Radeon HD 7500G Hp Sleekbook and everytime I start my laptop up, I get the message "no amd graphics driver is installed". I'm not sure why i keep getting this message. I was hoping for the sleepbook to be good for gaming like reviews that I read but it's not really turning out this way. Is there a graphics card that's good for gaming I could upgrade to? Or possibly a way to stop the AMD message coming up and fix the card?
