Where Can Find Windows Explorer In Event Viewer

I started up my computer and Windows explorer randomly froze up and hung. I didnt do anything to provoke it. I just sat here waiting for my computer to boot up.Then when I thought it was finished I opened firefox. Then Windows explorer just freezes completely. I tried doing windows key + r. It opened the run window but it froze. Then I tried moving my mouse on the right to open up the charm bar, ( I think it's called that) to hit settings and then restart. When I clicked settings the whole bar just closed out and would close out every time.

I right clicked on the task bar to try and open task manager. When I clicked on task manager it wouldn't ever open. So I couldn't even shut down properly. I just pushed the power button. Then I turned it on again and the same exact thing happened.So I shut it off again.

Then I turned it back on and went to msconfig before it froze up and I set it to boot into safe mode.Then I got into safe mode and ran a malware bytes scan and an avast scan. Nothing came up on either so I just went back to normal boot. The problem stopped now but I want to know what caused that whole thing to happen because it hasn't happened to me before.So I want to look at event viewer to see if that'll explain it. Where would I find that at in event viewer?
