Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

UE4.15 + W10 Total Freeze issue

Hi guys, I didn't found the solution on the forum, so i'm asking here.

I've recently installed windows 10 on my computer, here's what's inside : W10 pro version 1703 os 15063.0

CPU : Intel i7 980@3.33GHz RAM 24Go GPU : Nvidia GeForce GTX 760 (just installed the latest drivers)

I'm working on a project with UE4.15 since a week, i had no trouble using it under w7. Now that i'm under w10, the computer fully freezes. Can't move the mouse neither "ctrl+alt+del" The freezing comes randomly when working on UE4, and goes often when building lights.

When freezed, my only solution is a hard reboot... until it freezes again. I'm kinda lost here, can't find any solution. Just think it come from UE4.

Thanks for your answers ! Vlad

Hi Playsnak, seems here that it came from something else than Unreal. Looks like the issue is coming from W10. Also Freezes when computer is idle. Might come from thermical cooling that might not work well with some kind of weird raltionship with w10....
