Dell HD Graphics Gard Glitch

So basically, I've had this computer for a little over a year. I haven't used it all that much and I just got on it and there is an issue with the graphics card. The visuals glitch out a ton and it makes it almost unusable. I have the Dell HD graphics card and everything else seems to work fine. I have no idea what's wrong with it so any suggestions help. I also have some pictures The first s of a normal web page and the second is of the laptop trying to run a game.
