How much RAM does this system have in it?
I am running Vista Home Premium on an HP Media Center PC, model is m8000n. My hard drive light is on solid much of the time and flashes at all other times. This occurs even when the computer has not been used for several hours. I have run Nortons many times in an attempt to clear up this problem. The only infraction that nortons finds is "Tracking Cookie". I have also tried various registry cleaners to no avail. Any sugestions would be greatly appreciated. Thanks, Larry.
