I have a samsung laptop, AMD Quad-Core APU 4gb RAM 500gb HDD, onboard soundcard, Asio4all, and the snare is just in a sampler channel. I sorta figured it out, I had my laptop in power saver moder because it was dying earlier and i put it back into the usual high performance mode and it stopped the cpu meter from peaking and glitching, but it still spikes when the snare rolls come around.
