I was in AMD Catalyst Control Centre (CCC) and saw the AMD Overdrive function so me thinking this could cause no harm I messed with the settings. I didn't put the settings up high at all. I then click apply. Everything seemed fine. I then opened World of Warcraft.
Right when I did that I got red triangles all over and my screen froze. I panicked and shut my computer down. I then restarted it normally. Everything seemed normal again. I then opened CCC again. Right when I did that all the triangles appeared again. I then restarted and open CCC again I got in and turned the settings down.
I opened World of Warcraft again. It froze but then unfroze but I lost my cursor. I haven't messed with my computer anymore. I'm too afraid. Imagine its lagging because I turned the settings ALL the way down. Maybe I should just reinstall the driver? I'm pretty sure no hardware is damaged or my computer would crash as soon as I opened a program.
