troubleshooting device drivers with dpc problems

another little gem.  here’s what you need and some highlights:

process explorer
kernrate
hklm\system\currentcontrolset\services

1. run process explorer
• open the DPCs property
• check the performance graph - see if it’s high
2. if it is, run kernrate for 30-60 seconds
• ctrl-c to escape and view the results
• the offending item should be at the top or close
3. find the subkey associated with the offending item
• path is noted above
• modify the “start” value to 4 in order to disable it.  (at your own risk)
