    Hi all,
    I've been having a sound stuttering/movie stuttering/game freezing for short periods of time, occasionally. In the beginning I was thinking that it was due to the bad sectors of my Seagate HDD that came along with the laptop since day one. Recently I replaced the HDD with a brand new Hitachi 7200K drive, but the stuttering remained. Then I came across the possiblity that the problem be caused by a high DPC latency. This is my graph created by a DPC Latency Check tool, which is free to download at http://www.thesycon.de/eng/free_download.shtml

    I'm having a G71GX Best Buy ver. I don't know if this is really the problem, but would appreciate an advice or if someone else posts the results from the DPC Latency check to see if this is a common problem amongst the Asus laptops.

    Mine spikes up to over 60000. I have big red lines lol. I can tell its caused by nvidia powermizer, but i just have to turn it off. Stuttering in games, movies, and music.

    I also noticed that the high 60000 and over spikes are caused by the powermizer, especially when downclocking. But I don't know what is cauisng the regular ~2000-2500 spikes every few seconds and if they're causing trouble at all. I'm with Vista 64, Nvidia drivers 186.82. Read that people experience even higher latencies in Win7.
