Everything was fine after doing a fresh install of Windows 10 Pro, right up to the point where I installed Webroot, then I started to get the blue screen of death with the following message everytime I pressed a key on my Microsoft Wireless 5000 kepboard:

DRIVER_IRQL_NOT_LESS_OR_EQUAL.KBDCLASS.SYS.

 

I have been using this system for over 2 years without a problem. The PC works fine with a wired mouse and keyboard.

 

Thoughts or fixes anyone?

 

Regards
