One-time or short-term spikes are nothing to be concerned about, just as one-time CPU or paging spikes are not an indication of a problem.
 
As a program starts up or shuts down, it's likely performing some time-consuming task that's temporarily preventing other deferred procedures from executing, resulting in a short-term latency spike.
 
What you're interested in is the average latency while SONAR is running, and any periodic (recurring) spikes that might be caused by some non-audio interface activity such as a wireless network adapter continually broadcasting its presence.

Cpu throtolling? ive had a look at bios and my uguru setting and the cpu clock speed is set at default speed.. still get these messages using both latmon and dpc checker.

I'm I missing something??

There are numerous settings in the BIOS that affect CPU throttling.  
 
Note:
Some pre-configured machines have motherboards with very few BIOS parameters exposed to end-users.
This is done to keep less savvy users from fouling up their machine.  Of course, if the parameters aren't exposed, you won't be able to disable them.

ok... 
 
cpu  seems to be more or less stable.... I could turn off EIST (enhanced intel speed) and also C1E.
 
Latency is better but..   but red bars spike whenever video is played on web.
resinatlled newest nvidia driver for my card... 
 
seems NDIS 6.0 wrapper driver  seems to be causing some problems.
 

That's right Dave,  I've never been to concerned with spikes that happen when I'm opening and closing other apps, Things seem to work fine as long as all is in the low green when idle etc.
And yes Jim it was determined that Tascam's drivers were terrible. That's why I switched to a Focusrite. But now I suffer from pre amp issues. The Tascam had much better pre's. Hopefully the new line up has improved on the driver side. Craig seems optimistic.  We are talking budget interfaces anyhow so I really don't expect top shelf performance form any of them. I know what a good interface is but I just can't afford that right now. My system is working with no DPCLT issues. I don't use the laptop anymore and would never buy one for recording anyhow.

That's your NIC. NDIS means Network Driver Interface Specification and is MS's API for NICs. If it worries you, you can disable your NIC while doing audio stuff. Also, you can purchase a different PCIe NIC and disable the onboard NIC.
