Hey all

So the last 2 days on 3 separate occasions my computer has crashed and restarted, when it happens my screens (2) either turn black or a random colour (light greyish on 2 of 3 occasions). All 3 times have happened whilst I have been watching netflix, in-between these crashes I have been playing games like Fallout 4/World of Warcraft/League of Legends with no crashes.
A friend told me about the microsoft event viewer and told me to look for things saying 'Critical', the ones I have found are all pretty much dead on the times the computer crashed, he told me to post here and post the events. Any help would be greatly appreciated.
