Thanks Andre! I solved my problem I couldn't find a latest driver for window 7 so I just disabled the device and removed the driver (wasn't using the wireless anyway) and now there is no more problem! Thanks again man. Much appreciated

Hello Andre. Nice tutorial. It helped me greatly to find the source of high CPU usage. But even though I know what is causing the problem, I don't know how to fix the problem: halmacpi.dll This halmacpi.dll is using 50% or more of my cpu for 2-3 seconds in every 25-30 seconds interval. This causes a noticeable lag or unresponsiveness in my computer whenever I am doing anything that is CPU intensive. halmacpi.dll is also a part of a window system process so I can't exactly remove or shut it off either. And searching around the internet didn't help me much for finding a solution. I've attached the screenshots of table summary. A link to the downloadable latency.etl is here: http://www.megaupload.com/?d=PNTZL0GU I appreciate any help or advice you could give me. Thanks
