Earlier today I was playing a game like normal, with nothing special or new, and I heard a pop come from my computer. I checked the inside and nothing looks broken, although my performance went down significantly. Since I have an APU, I also checked my CPU usage and it is higher than I have ever seen it go before. I am thinking what happened was my graphics card busted and my APU took over, explaining the decrease in quality and performance, and rise in usage. My graphics card is still relaying images and data to and from my computer and monitor, which has me confused. Is my graphics card busted?
