It's likely a hardware issue. Make sure that your drives are all on DMA and not PIO (or does that cause spikes in interrupts, not System? I don't remember, but it's a place to start)
A CPU overclock could not cause this. But as I suggested in my post, a problem with storage could, and if you are not using regular storage drivers, well, that would be a good place to start.
Ok, i see. Well i have installed the "officel" storage, now only time can tell if its working Usually this problem coms: a few times a week.
Now I run with the official (intel rapid storage) a few days, and has worked well, but now for 5 mins ago starts NT Kernel & System eat up about 13% cpu power again. What the hell can it be wrong?
it is driver issue. to identify the driver in qustion, enable driver verifier(verifier.exe) click run>verifier.exe select one driver at a time and let it run and look for deadlock and the upgrade -conservative
Thanks for your help, will be testing the hint you gave me. But are you sure it's driving problems? tnx.
It's definitely a problem at the driver level or lower (driver, firmware, or hardware). It's unlikely to be a Windows or application problem.
Hardware = grafikcard? Cpu? Memory? Moderbord? Harddrive? Do I need to replace all part to get the computer to function normally?
Not CPU, RAM, or HDD (the controller is still a candidate). As for which, there is no way to tell without more diagnostic tests. Did you try to suggestion in post #7? That might help you narrow down the culprit. It's either a driver or the hardware controlled by that driver.
I'm trying to work out how to dispose of "verifier.exe" but im a bit lost, is there any guide or similar on this? Thanks for all the tips guys
