Problem with dv7-6140ew - is this a processor problem ? (i7-2630qm).

Question

Hello all
As I mentioned in title I have a problem with hp pavilion dv7-6140ew (i7-2630qm) Win7 64bit.
This is a brand new laptop I bought him few days ago
Of course I notified this problem to the hp support center. But they did not know what it could be.
But may someone will know where the problem is.
I would like also to ask whether this is the normal behaviour?
I have terrible interrupting (It looks similar to old problem with HDD witchout DMA) I saw, that it took place while the kernel process suddenly takes the large amount of the processor space. For instance
by the mcAffee process (the antivirus) but it takes place also with other
(eg at uninstalling of the software). But not always - There is on no rule.
I recorded the example-film with 3dmark03 (I added the music from winamp) and in 0:25 the McSvHost.exe process start - which is visible on the photo.

Another issue, that I found, is that, If process takes suddenly large amount of processor space in each of 4 core (8 with turbo boost) the error take place. For instance mcAfee process McSvHost sometimes cause such error. But it disappear when I change colligation in task manager for this process to be used by for instance one core.
Does anybody knows what is going on and what cause it ?
