Found A Solution To My Spikes and StuddersI have been having problems for sometime with intermittent spikes in the cpu usage and coincident with that what have been referred to in these forums as hicups, short pauses, intermittent freezes, etc.
I installed a clean copy of windows on a new hard drive, did all the updates including Sager drivers and it was still there.
I sorted through tens if not hundreds of pages in these forums and did not find anything concrete. 
I had developed theories on bios problems, memory problems and one hint at the wireless network controller.I had the computer drop into sleep mode and when I woke it up, the problem had disappeared. My problem had been occurring at 1 minute intervals like a fairly regular clock. When it happened, mouses studdered, music stopped and dvd's paused. After the wakeup everything was fine...until I restarted.
I downloaded Wintasks and Speed Up My PC tonight thinking maybe I had a process overload problem. I sorted through the processes, got rid of the junk and had no more success. I spent some time getting to know Speed Up My PC and noticed that there are some real cool charts that allow you to watch cpu usage among other things. I began to watch the phenomenon and noticed that the cpu spike did not include increased memory usage. It did however coincide with a large spike in the internet bandwidth usage chart.
I went into Device Manager and disabled the wireless network card and the freezes stopped. I enabled the card and they started again. I had updated the driver with the Sager driver so I decided to look elsewhere for another driver. I downloaded a new driver off the Gigabyte website and viola, the card works and no more hesitations, freezes, hicups, short pauses or intermittent freezes.
I know not all the solutions some folks find work for everyone. I wanted to get this out on the web though in the hopes that some other sufferer may find relief.
