A nice tool to use that hasn't been linked yet is LatencyMon from Resplendence. Lots of good info and download here: http://www.resplendence.com/latencymon

It gives you much more info than dpclat.

LatencyMon checks if a system running Windows is suitable for processing real time audio by measuring DPC and ISR excecution times as well as hard pagefaults. It will provide a comprehensible report and find the kernel modules and processes responsible for causing audio latencies which result in drop outs. It also provides the functionality of an ISR monitor, DPC monitor and a hard pagefault monitor.

LatencyMon will display the execution time of each ISR, DPC routine and hard pagefault and will resolve them to the drivers and processes responsible for executing them. It will create a comprehensible report but it will also represent all sampled data in a detailed manner allowing you to perform in-depth analysis.
