Try Process Explorer, (Mark Russinovic). Download, unzip into a directory somewhere, create a shortcut or run it from the directory. It's an EXE program, not installed through Windows. You can also find more info on Window's system problems on his site. (He founded Winternals Software and published a lot of freeware utilities like Rootkit Revealer, Process Monitor, File Monitor, etc. He was the guy that caught Sony's CD music DRM rootkits.)
Process Explorer can expand on what you're seeing in Resource Monitor.
