Hello, I've been having this issue for about two weeks now and I can't think of anything that I've done that would cause this. I have 14GB of RAM and a 3.07 GHZ i7-950 quad core CPU, an EVGA GeForce GTX 660 FTW, and am running Windows 7 Professional. A popup keeps appearing saying my computers performance is slow, and that I should switch to the Windows 7 basic theme. Sometimes whenever I play games (Specifically Counter-Strike: Global Offensive), it switches it by itself and tells me that it ran out of dedicated memory to support the Aero theme. Any idea why this is happening? My CPU usage and memory usage never really go above about 25% while sitting idle, and they almost never go above 80% no matter what I'm doing. Any help is appreciated.
