problems with windows 10 and google chrome

since loading windows 10 i have seen a number of frustrating issues when using google chrome which i have never had before. The most frustrating of these (i have a touch screen laptop) is if i drag the cursor over the screen it resizes either larger or
smaller which is not what i want. Not a techie so whilst i have tried to fix it looking at other issues i have still not been successful - any ideas how i can fix this please?

 

Computer shows blue screen and tells me that atikmdag.sys failed.

Windows 10 stops my computer and then gives me a blue screen. tells me that my atikmdag.sys failed. Have tried MS help but still have this problem. Any suggestion besides throwing away this computer?

 

You may have to re-install clean. However, you can try doing a reset first.

Settings->Update & Security->Recovery->Reset This PC
