No reboot needed and it's documented at http://www.microsoft.com/whdc/device/storage/IDE-DMA.mspx
If it is this issue, that will cure it.
If you do not perform the procedure, please tell why.

I have an HP Pavilion notebook that has issue with playing audio. Whenever I play music or view content with audio the sound stutters occaisionally. The problem is more likely to occur when I am opening a program, which leads me to belive that it's a memory issue, but I have a 256 in there already. Any ideas?
Also, my battery now only lasts for 15-20 minutes or so when not plugged in. The machine is about 1.5 years old, is this normal?
Thanks
