The Engine constantly crashes, how to fix it?

The engine crashes randomly a lot, sometimes after I try to click something(not anything specific, just a button) or just crash without me touching anything.
The crashes are getting more and more common, with some in less than a minute of reopening the engine.
It’s getting really annoying that I have to restart the engine every few minutes and probably lose some progress.
technical data:
win 10, 8gb ram, gtx 660, i5 4460, ue4.15.0
edit: managed to identify 3 different crashes:
One is simply the engine freezing for a few seconds and then crashing.
Another is that all the engine screens get weird and empty, I can still click on things but the screen doesn’t change, so I can at least save before closing in this one.
And the third one is a weird screen tearing that freezes the whole computer and then crashes the engine, and a few time made me go to blue screen.
managed to screenshot the tearing:

edit edit: I have no idea how to format this message into a comfortable text.

First, to make sure it is not your computer how causes the crash, try if this happens with empty or template projects.

Then you could post the contents of your Log file, this will help to identify the error.

When the above happened did you click on compile just beforehand? Do you have the latest drivers for your video card? When the engine crashes do you get a crash report screen? If so what does it say? Did you write down your bluescreen error code by chance? If so what was the exception code?

As far as I can tell its not the compile that caused it(although I did have that and fixed it).
Latest drivers.
Yes there’s a crash report(of course not on the 2nd kind of bug, because there I’m kind of turning it off myself), And for some reason the crash report said I’m missing some debug files, I could swear I downloaded the debug stuff but maybe I missed it.
Didn’t manage to write down the blue screen as the pc immediately restarted.
Tried working a bit more after posting, and the crashes got more and more common until I gave up on it for today.
Edit: I know, its not a lot of info. I will try to install the debug stuff and report asap.

Will try that in a day or two, a bit busy tommorow.
I’ll l try to report how it went.

Hey barr,

When you get the crash window if you submit your loginID/UserID that appears I can look up your crash information in our database (assuming you submit the crash and can’t get the callstack or logs).

We have not heard back from you in a few days, so we are marking this post as resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will follow up.
