Hi there, first of all i'm sorry for my english. Few of my games suffers by stuttering, but only a few seconds (1-5). Only I noticed is in that period the GPU usage drops to zero. First I think that is the hdd (5400 rpm), but in that period while the game stuck the led didn't flash. The games i've noticed this: Crysis (sometimes long 5 seconds freezes), Team Fortress 2 (short freezes). Everything seems to be ok, only the GPU Usage drops. I have absolutely no idea what causes it. Any ideas? Thank you.
