Hardware Interrupts and DPCs Issue

by vijaymm2 Aug 27, 2011 11:55AM PDT

i am using Win XP Pro SP2. When running some application my CPU usage goes high...
i have seen that only the WINDOWS TASK MANAGER --> PERFORMANCE window CPU USAGE
HISTORY left side graph USAGE is 100%. After downloading the Process explorer.

i
found that Hardware Interrupts and DPCs Issue is the issue.
Here with i have added the logs. Before copying the logs the usage is 45%. my
audio is also effected, not able to hear the audio properly lots of interrupts and suddenly CPU
usage goes high

How to solve this issue?

An Audio DJ finally had everyone look at the laptop and they finally swapped the laptop out and the next laptop did not have the issue.

Go figure how much time was lost on that one.
