Hello,
I have an 2 units of Acer Veriton S670.
They both have this problem of high CPU usage (60 to 80 percent) while idle.
It is due to hardware interrupts, but the DPC Latency tool doesn't show any spike (high red bars). It just remains in the low green area. (Hope I'm making sense).
How should I proceed from here?
More info:
unit 1 is running on WinXP SP3, I have run windows update and selected all the critical updates. I also have installed all the latest drivers.
unit 2 is running on Win 7. At first this had the same problem, but it went away after I installed all the recent drivers.
Both units have ATI Radeon 4350.
