The easiest method of finding out whether your device has been stopped and takes just a few simple steps:
Firstly, go to the Windows Search bar and type 'Device Manager'.
Once in Device Manager, simply find the 'Display Adapters' drop down and you will see your graphics card.
(A quick note - If your card does have a code 43, you will see an amber triangle over your device with an exclamation mark.)
Finally, right click on your graphics card and select 'Properties'.
Once inside properties you will see the 'Device Status' tab where it will say whether or not you have a code 43.
