Hi Humble, if you want to check your irq's, got to my computer, right click, properties, hardware, device manager, open up the bit you want to check (ie , sound card etc) right click and its under resources............also, have you overclocked your video card at all, as it sounds like aquamark is resetting something (allowing ah to run) then if you run it without whatever it is being reset, its crashing?
