Is there any updated driver in the link I supplied in my earlier post?

rlyacht · 28 Nov 2012

I didn't see one at the Ricoh site, but I figured out (I think ) that the Ricoh driver was for the integrated webcam on the machine (Lenovo Thinkpad 420s). So I updated using the driver from the Lenovo site, and it seemed to me from looking at the driver in Device Manager that the date bumped up from 2010 to 2011. Do you still see that driver as being the same old one, i.e. I didn't update the right thing? THanks for your help!

Yes, you updated the right one, but its date is now 2011, and still, the last crash indicated that same thing.

You may enable driver verifier.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier. It will make the system a bit slow and laggy, but pick the faulty drivers up in the crashes.

Let us know the results, with the subsequent crash dumps, if any.

OK,I've got verifier on. Of course now I can't get it to crash

Got a crash. Attached is a new set of files. Thanks for your help!

The situation is just the same, with updated driver, too.

Code:

Can you stop using it, and see if it changes anything?

rlyacht · 29 Nov 2012

Sure. Just to be sure, to do this I would disable the device using that driver, using device manager.?

Arc · 29 Nov 2012

Yes. Disable it in Device Manager.

rlyacht · 30 Nov 2012

Since disabling this device, I 've had no problems! I guess that was it. Thanks very much!!

What would you advise if I want to have a webcam on this machine? Should I just buy a cheap webcam? I don't use it a lot, but do like having it. It seems that I'm using the latest driver from Lenovo, and also that the Ricoh component was discontinued by Ricoh, so I'm not sure there will be any updates.
