I am having performance degradation after a random amount of time running my machine. Generally, I notice during video playback that the sound becomes full of static and the video playback choppy. The resources monitor indicates that during these times
a large portion of the CPU (20% or so) is being used by system interrupts. The problem resolves after restart, but recurs regularly.
I ran xperf during one of the periods where interrupts were high and the results can be found at these links:

As can be seen, the CPU is being occupied by USBPort.sys. The interrupts are being generated by hal.dll, dxgkml.sys and USBPort.sys
I am running a gateway sx2802. I've added a wireless card as well as an ATI Radeon 4550 graphics card, which I have connected to a receiver with an HDMI cable. I am running windows
7. The only USB device I am using is a wireless logitech keyboard.
Anyone have any ideas on how to fix?
Hi,
To optimize Windows performance, try using the Performance troubleshooter to automatically find and fix problems. The Performance troubleshooter checks issues that might slow down your computer's performance, such as how many users are currently logged on to the computer and whether multiple programs are running at the same time.
To run the troubleshooter:
• Click the Start button, and then click Control Panel.
• In the search box, type troubleshooter, and then click Troubleshooting.
• Under System and Security, click Check for performance issues.
You can also use advanced tools to troubleshoot performance problems in Windows 7.

• To get to the tools, type Performance Info into the search box in the Start menu and hit Enter.
• In the Performance Information and Tools windows click on Advanced Tools.
• It opens up a list of different tools you can use to monitor different aspects of the system performance. From here you can do several things like defrag the hard drive, check Event Viewer, and even re-rate the Experience Index score.
• Notice there is a column for Performance issues you can click on to get additional details on how to correct the problem.
• Resource Monitor is a great tool to monitor what applications and services are using up your system’s memory, processor, disk usage, and network activity. If you find a service or program that is frozen or taking up too many resources you can close it out.
• You can even generate a system health report. With the help of this you can go through a very detailed analysis of virtually every aspect of your system.
