Perhaps you have something failing on the card. Or even your system memory could cause funky things to occur. I had system crashes before that all pointed to my graphics card but after warranty and research it turned out that my system memory was failing and not the card.
Some games have different effects on the hardware. It is how the hardware is addressed in the games that can cause this.
Error messages that may occur or even the messages you get with Blue screens may make it appear to be the graphics card but 9 times out of 10 it is your memory and not the graphics card that is causing the problem. Do you overclock your CPU or memory? Have you ever overclocked them? You don't have to overclock them for them to fail but overclocking without the proper ventilation or cooling can cause them to wear out a lot quicker. Even if you overclocked them at some point but do not anymore.
BTW, the trolling responses is from the title of your post and not the bulk of your message. I almost posted an amusing response myself until I read your post above mine.
Arg how would I know it's memory? In my research I keep hearing it could be my PSU, Video Card, MoBo, and now my RAM that would cause the issue. I wish I knew people who had spare PC parts in wihch I could test with...
Would the memory really cause the signal to die out in my video card? Keep in mind the PC can still boot into windows fine, I just get no video.
