Video playback is choppy. The frame litterally freezes for a split second or two in between spirts of several seconds of normal playback, over and over during the lenghth of any video piece. It even causes Google Earth to function this way while displaying its satelite photos.
The odd thing is that the processor performance percentages shwon in the task manager are severely erratic.
The %age stars out low on startup, goes to about 50 or 60 % or so within seconds, and then hits 100% for a "split second", before going back down to single digits, from which point the cycle repeats. At the precise moment that it hits 100% (actually, the precise moment JUST before it does this), video playback freezes until the %age goes back down. So, my playback problem is directly linked, it would seem, to the eratic performance of my processor.
I works like this. Second one, %age=15, playback=fine, second 5, %age=65%, playback=fine, second 8,
%age hits 100, playback=FROZEN for a "split second", second 13, %age=12, playback=fine, etc.
That is, playback is normal for 5 seconds, then freezes for 2, then is fine for 3 seconds, then freezes for 1, then is fine for 15 seconds, then freezes for 4, etc.
I have tried everyting but wiping the drive, such as virus removal, spyware removal, defragging, registry cleaning (the latter of wehich seemed to fix the problem for a day or so, and then, only once), etc., and I'd REALLY like to avoid doing that.
