So, I’ve been fighting a stuttering issue with my laptop, an Alienware Aurora m9700, for the last few months now. Whenever I played a movie file it would start stuttering badly after about 20 seconds, and then every 10-20 seconds for 2-3 seconds. In .mov files, this affects the sound, but in all others, it affects only the video. The same held true for games. I was unable to play any games (on a gaming laptop!) due to the crippling drop in FPS every 10-20 seconds. I tried reinstalling the OS a few times. I tried updating this driver or that. I fiddled with BIOS settings. I fiddled with video card settings. I spent hours researching it online using variations on the terms “stuttering video xp seconds fps chop ‘frame rate’” and a host of others. Two nights ago I was looking through the Event Log on a whim on a completely unrelated topic, having all but given up on the stuttering issue. At that point, I was all but convinced it was an SP3 issue, and there was nothing I could do about it. But I came across this: “The Acpi 2.0 _PCT object returned an invalid value of more ยป
