So lately, as in the last couple days I've been having problems with my computer freezing up. It happens semi randomly when I'm in an MMO. First time it happened was in DnD Online and my screen freaked out and it looked as if it was bleeding in pixel form. I thought it was an effect from the game since my UI wasn't effected at all. At least until my whole computer froze. This has happened twice while in DDO at random times. Third time it happened was in LOTRO. Same thing happened but it was black pixels instead and same side effects. Again no UI was effected, only the "background" area. Do you guys think this would be a graphics card problem? shader problem(since UI wasn't effected)? or just something else all together.
