There are no artifacts while playing, just far less FPS and the graphics are unsmooth.
Something's definately amiss then. If things were running fine for a length of time, then suddenly stopped and you did NOTHING WHATSOEVER (emphasis on that), you need to start poking around. My first stop would be to have a good look at both your graphics card, and your RAM. Is your RAM still reporting at the same size? Run a test on it to see if you're able to address it all. Have you changed your page-file sizes? What about voltages in the BIOS? Are you running any OCing utilities like CoreCenter or whatnot?
Also, do you have another computer you could try the vid-card in?
I doubt it has to do with the drivers for the card, or your DirectX. Nothing would work right from the start if those were faulty, and they don't change on their own (again, you didn't do anything, right?).
Also, check your powersupply. Are you experiencing any brown-outs?
