I have a Dell Workstation (Optiplex 760) with a fresh install of Windows 7. Right from the get go, I noticed that the second core is running around 20-30%. Taskmgr is not that helpful so I installed Process Explorer. While reviewing the cpu information, Hardware Interrupts bounces between 20 and 35%. I downloaded RATTV3 and created a log file. After 5 minutes I checked the log file but to my disappointment the "Cumulative Histogram for:" is blank. It gives me all the information except the culprit!!! (bangs head on desk). After visiting Microsofts RATTV3 site, it states there is a known bug with vista and windows 7 in regards to displaying a blank value.
Is there any application available that can tell me the file name (drivers
) that is causing the excessive hardware interrupts?
-- To give you a little background --
Windows 7 installed all drivers except HECI and SOL (AMT). I installed these which were available on Dell's website. Before these drivers were installed, I was still experiencing the second core cpu excessive usage.
There is nothing in task manager that points to high cpu usage (which is why I am using process manager).
I tried disabling common devices to see if the usage would drop down (all communication ports, NIC, Audio, HECI, SOL).
Anyone have a clue or experience this issue? Any help would be greatly appreciate.
