Vista Business 64Bit Nt Kernal and System using 70-75% of CPU until computer goes into Sleep Mode
I have just built 2 new computers at home and they are my first systems I built that use Vista.
One is my old computer that I setup for my kids:
Computer 1
AMD AM2 4400X2
4GB ram
500GB Sata 2 HD
Nvidia 590SLI chipset
7800GT 256MB
This is my new system:
Computer 2:
AMD 9600 Phenom Black Edition X4
8GB PC 1066 Ram
Nvidia 780A Chipset
Nvidia 280GTX 1GB video Card
2X250GB Sata 2 HD's (Raid 0)
One computer 1, everthing seems to run great, on computer 2, everytime I restart or boot up windows, NT Kernel and System takes up 2 cores and 1/2 of the other 2 non-stop. This happens until I put the computer to sleep, then I never see it again until I reboot again, and it drops to 1-2% at max from then on. I used process explorer and it gave no more information about it , simply naming the process System.
I have tried reinstalling windows, which did not help, and tried it with the hard drives in raid and non-raid, and nothing helps. This is at most a minor annoyance now that I know that putting the computer to sleep (even for 5 seconds) and it is fixed, however, it still bugs me.

ASKER
I got into the threads info and got the name of the start address:
There are 3 processes that are exactly the same - ntoskrnl.exe!FsRtlNumberOf RunsInBase MCB+0xc
There is one process for each of the first 3 cores, then it does not touch the other core.
