kernrate and cpu

[dec]

I have installed process explorer and kernrate to determine why my cpu
is 100%
I can access process explorer but I cannot access kernrate even though
it is installed and I have an icon...what is wrong?

In Process Explorer are you unable to drill down (click the +) under
System to expand it out to narrow it down?

If PE shows a + sign next to system, you need to click the + sign to
expand it, then see what is going on.

Here is a little write up from Mark Russinovich about using kernrate

Googling for Deferred Procedure Call will get you many hits and the
problem seems to usually be closely related to gaming, intense video
audio/operations, audio/video/network hardware, video drivers...
Sometimes just reseat the RAM, or replace the CMOS battery does it for
some folks.

Here is a popular DPC monitoring tool:
