[How to get the cause of high CPU usage caused by apps?]

the BLKWGDv8.sys indicates an issue with the Belkin Wireless G Desktop Card driver. Your driver version is 6.1061.1115.2006. So try to get an update because this driver is from 2006.

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

[How to get the cause of high CPU usage caused by apps?]

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.

I appreciate any help or advice you could give me.

Thanks
