Okay, I'm having a problem with my graphics card and or graphics card drivers. Often when I go to open a game such as Oblivion, Combat Arms, Spore, etc, a whirring sound comes from the PC tower and it seems as if all graphics input is shut off. The screen goes black but remains on (I can't alt tab, alt f4, etc). Is this my graphics card or something else? If you need more information, feel free to ask, and I'll add it to the bottom of this post. My system and display specs are below:
