help with non-responsive keyboard: device manager error code 39

Gotta love Windows (XP SP2). Shut down last night and all was good. Booted machine today and noticed keyboard wasn't working. Device manager shows a yellow alert with a code 39. I uninstalled and then did a find new hardware to reinstall, but it reinstalled with the same alert. Tried booting in between and same results. Tried finding an update. Windows found no update and I couldn't find a keyboard driver on the lenovo support sight. I'd appreciate some guidance. Thanks in advance.

 

Is there anything in PC Doctor. Maybe try re-seating the connector.

 

After that sick feeling in your stomach and despair had set in I posted here...and of course afterward one more web search turned up a clue which led elsewhere...and I found that an update to Threatfire which I run had failed to copy a new keyboard driver tfkbmon.sys (used to assist in detection of keylogging apparently) into the drivers file. Things worked fine after update but the reboot was the culprit and I had forgotten about the program asking to install an update. Thanks
