I've been using ATT for years with nary an issue, but suddenly I can't start a bunch of different programs without them crashing upon startup. Programs include, but are not limited to ArmA II, Everything (the program, not literally everything), GTA IV, TuneUp Utilities, and Steam. I get "x has stopped working", and when I click "View problem details", almost all of them mention raphook.dll under Fault Module Name. When I close ATT, they run just fine, however. I have to set my clocks, then close the program before running games or they won't boot. Normally this wouldn't be a big deal but that means I don't get the overlay anymore in games. Research says that it could be caused by faulty RAM, but it passes Memtest with flying colors. I underclocked my sticks back to stock speeds though, just to be safe. What causes this problem, and how can I fix it? I'm not about to switch back to CCC because it's overclocking function isn't very good. Suggestions?
