ThinkPad T420 blue screen

Hello guys.

My T420 restarts on his own here and there showing this blue screen (please see attached file).

 

Do you know what could be the problem?

Re: ThinkPad T420 blue screen

Welcome to the Forums Ninjay.

 

The crash might be caused by your INTEL wireless LAN Driver, Netwbw02.sys.  Please update the latest wifi drivers.

 

What graphics card do you have? Please check Control Panel >> Device Manager >> Display

 

Update us how it goes.

HD Graphics 3000

I updated driver as per recommendation. I actually reinstalled windows and updated drivers and so far it did not fall.

 

Thank you for help.

Anything in the event log?  Can you run a memory test?

Re: ThinkPad T420 blue screen

Sorry for delay. It is actually laptop of my brother and he lives in another country. So i do not get in touch with him too often.  I did memory test and everything was OK but laptop was for some reason slower. Then his win 7 updated itself (microsoft policy Smiley Happy) on win 10 and he told me that now his laptop is working well and fast without any problems. So it looks there was some software problem. Thanks guys to all of you who tried to help.

Best regards

Tomas
