When it's at 99 percent that means the Windows OS is doing nothing. All unused cycles are supposed to be in that process. Sorry, have you used NT, Windows 2000 or XP before?
I have a serious problem. Each time I boot my computer it goes through the normal start up procedures and loads everything. Once complete my computer immediately begins an idle process that slows down my computer ridiculously! I don't see how there even can be an idle process when I am using the computer. The LED light that signals the computer thinking is solid and never blinks and the sound my hard drive being read is always going. I have included a picture of the Task Manager.
I have tried to kill the process several times but I am "denied access" from doing so. Any help or suggestions for this problem would be GREATLY appreciated!
By the way...
I'm running Windows XP media edition with 1GB of RAM and a Centrino processor.
Hope that helps.
