IE not working on Windows 10

[SpeedMattersNot]

So, I have been using Windows 10 ever since Chrome wouldn't allow me to watch Sky Go. Out of the blue, IE will now not even open on my Windows 10 laptop. I have tried Googling for the symptoms but nothing it that obvious...

It just opens a dialog box up stating "internet explorer has stopped working; a problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available".

Any help appreciated!

...on top of this, I have just tried to open Steam and it has said something about my system doesn't support 'Alpha Blending' so it won't open. I am assuming these are related?
