[Bug] PC crash

Development Platform & Builds

Hi guys :slight_smile:

I dont know if this has already been reported or if the engine causes this problem, but sometimes (after I have updated to 4.4) my PC just crashes during doing some stuff in the UE4. Unfortunately I dont get any errors or messages → my PC just restarts after the crash and everything is fine again. My specs:

  • Graphics Card: GeForce GTX 660 Ti
  • Processor: i5-3570 3.40 Ghz
  • System: Windows 7
  • Ram: 8 gb

Let me know if you need more information. :wink:

Do the logs (Saved->Logs->YourProjectName.txt) have any information in them? What kind of things where you doing at the time in the Engine when it crashed? I’ve been on 4.4 (Source code) for a while and have yet to experience any crashes unless I’m running my project (which is usually me that is causing the crashes).

Yep, sorry, forgot the log :slight_smile: Last time I was doing nothing in the editor (was writing a gameplay plan onto a piece of paper ^^) and two days ago I was editing a landscape. → I’m using the fps blueprint sample without any changes in the blueprints (I just did some mesh and material testing)

Some more information:

  • no pc parts are overheating
  • before 4.4 I never got this problem
  • the project is on my 2nd disk (E:)
  • I’m running the editor with admin rights
  • not the latest gpu driver → normally I always use a version behind the latest one

Hmm, just happened again → this time I was playing my level in my project

Hey, . I’ve been looking into this ‘crash’ since yesterday and it’s pretty hard to pin down. I can’t reproduce it on my computer, and my coworkers don’t have this problem either.

One possibility is that somehow, your version of the engine has a memory leak. Next time you’re using the engine, open the Task Manager, switch to the Processes tab, and watch the Memory value. Just check periodically that it isn’t taking up more memory over time.

A few more investigative questions: Has this only happened in that one particular project? Have you tried verifying or reinstalling the engine from the launcher?

Hi, this is happening in every project (as I mentioned above even in a “clean” template project). Currently I’m reinstalling my display driver and when it still happens I will check the memory usage + reinstall the engine again :slight_smile:

Thanks. We’ll get this figured out!

Ok, now I dont get those strange crashes anymore → I updated my display driver a 3rd time + reinstalled the engine :smiley:

Glad you got things working! Let us know if the problems reappear!
