Is something wrong with my PS3?

Got a camera? try to take a picture.

buuut, it sounds like geometry artifacts (wierd spikes and lines, usually connected to models) which is a problem with the graphics core. Not the video memory. Video memory problems yields white or colore snow on the screen, kind of like hundreds of dead pixels.

As for why some games and not others? Well...It may be a problem with a very specific part of the graphics core that doesn't really get stressed by those other games. If you played some of those other games for awhile though, you might be able to squeeze out some geometry errors.

But anyways, YES there is something wrong. Get it replaced, It happens
