Once you run it, first check to see if there's another process listed beneath it that may be causing this. Then, just right click on the offending process and select "Properties", then select the "Threads" tab. The listing there may give you some clues as to what's using the most of that process.

TID 5284 Start address igfxsrvc.exe+0x13292
TID 5300 Start address igfxsrvc.exe+0x6850
TID 1872 start address RPCRT4.dll!|_PpcSend+0x18f
TID 4296 Start address RPCRT4.dll!|_RPCSend+0x18f
When I look at the properties of the svchost.exe itself, under the service tab it again lists PlugPlay and DcomLaunch. The threads taking the CPU% are both ntdll.dll!Rt|UserThreadStart. There are about 8 or so thread IDs with that same address, but only two take up any CPU%. I also noticed that the start time of both of these threads is about the same as the current time, or a few minutes prior.

Even though the driver may be the most up to date - it may still be corrupted. That's why I suggested removing the old one first, and installing the freshly downloaded one.

The next thing to check would be your startup programs - stopping each one of them and then rebooting to see if it fixes it. You can use MSCONFIG for this, but I prefer disabling things in Vista through the Windows Defender → Tools → Software Explorer interface.
