i have the lenovo x200 with vista 32 bit installed, and after an hour of use the cpu start jumping at around 40-50 % of load.
with process explorer i saw this is due to hardware interrupts and not by any specific service.
i saw a few threads regading this problem, but no solution (just standby and resume, but the problem keeps returning..)
can anyone pleaseeeeeeee help me??

Boim welcome to the forums
Hardware interrupts are a common thing in any OS .Depending on the priority of the hardware device a CPU has to provide its resources,hardware interrupts occur often.Do you get more interrupts when you are perfoming large data transfers?if so the system's DMA creates interrupts to transfer that huge data
You may generate a system health report from the tools menu in control panel and get reports on the working of various hardware resources and system response time.
hope this info helps you

i can't figure out when or why it happens (for your question regarding data transfers). but when it happens, it does not stop until i put the computer in sleep.
i did not find the please to create a system health report. can you be more specific (i am using vista).
and thanks for your help

controlpanel-->system and maintainence-->performance information and tools-->advanced tools(select this option from the left side)
then select the option "generate system health report"

ok, found it.
but i am not sure what i am looking for.
is there a category there where i can find the hardware that causes the hardware interrupts?
otherwise, what should i look for there?

Solved by Czech phorum.
The problem was caused by graphic driver from lenovo not updated for long.
I downloaded lastest from intel and installed from zip.
lot of czech guys tried the same and helped.
The discavered this behaviour since they need to use graphic a lot and changed driver to newer from lenovo and got the problem.
it looks it solves problem.

This isn't a specific fix for this specific issue, but I've found with a very similar "excessive hardware interrupts" scenario I experienced over the past few months (Windows XP, Thinkpad T61) that:
