I'm not a big antivirus fan myself. I run two, both of which I can shut down easily, Malware Bytes is one and Spyware Doctor is the other. Most of the time both are off because I need real-time performance for hard disk audio recording, eight to twelve 24-bit tracks at a time. I really can't have any background interference, you can't explain a missed take to a client.

I usually scan once a day. I think I've had two viruses in the past 25-30 years... I dealt with the Internet when it was pretty much text only. (Lynx) What a ride.

So, yes, download Malware bytes, it doesn't keep things running after you shut it down.

As for your CPU use... looking in task manager, is Audiodg using the cpu?

If the AV apps dont show a virus, and if other things dont seem to pan out sometimes on multi core processors an applicaation can use what is caklled affinity. that is it will only run on one core using up all of that cores cpu cycles (100%) but it will show in tast manager as 50% on a two core system.

If that is truely the case and you have identified the offending application you can first create a dmp from the process for us to examine (right click>create DMP file) and you can set the affinity for both processors. (see snip)

Basically some apps (poorly written ones) forget that they should be using both cores

I just did a search and found this page: http://technicallyeasy.net/2009/03/f...igh-cpu-usage/

I've disabled all enhancements and waited for a while. Problem seems to be gone. But I need more time to confirm this..

That was going to be my suggestion and in fact why I asked if audiodg was using the cpu. The enhancements are DSP based and because of their nature are single threaded (one processor core). It's possible for DSP to use quite a bit of processor, especially with high sample rates.
Time will tell.

Might want to check Control Panel/Power Options --- select "Change Plan Settings" and then select "Change Advanced Power Settings"

Scroll down to "Processor Power Management"

Make sure both minimum and maximum are set to 100% when the computer running off the power adapter.
