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"

Everytime i open the editor my computer crashes and resets

Everytime i open the editor my computer crashes and resets

I am able to open the Unreal Project Browser, however when i create a new project, or load a previous project, the editor crashes my computer and resets. attached is my dxdiag.txt

Also after the reset/restart i can't find a crash log to see what the problem is.

Hey Rhinosaur,

Can you give us more information?

  1. Has this always happened?

  2. Does it only happen with a specific version of the engine?

  3. Are you using the launcher or compiling from source?

avatar image Rhinosaur Oct 14 '14 at 05:03 PM

it has happened since i've had the engine. from 4.3 to 4.4.3. some. i've used 4.2 for longer periods of time, but it always ends in a freeze and then computer restart. i am using the launcher.

avatar image Jonathan Dorman STAFF Oct 14 '14 at 05:49 PM

Do you mean that the BSOD doesn't happen immediately in 4.3 and in 4.2?

avatar image Rhinosaur Oct 14 '14 at 06:25 PM

correct, the BSOD doesn't happen immediately with the previous versions, but it does happen.

i can replicate the process tonight when i'm home (7pm PDT) and write a step by step and how long it stays up in the two versions i have on my machine (4.2 & 4.4.3,[ 4.4.3 overwrote 4.3]) and, if it is needed, video the steps i'm going through.

i know getting the engine to work on many different types of hardware is tricky so i'm willing to put in the debug time :)

thank you for you questions and responses so far :)

avatar image Jonathan Dorman STAFF Oct 14 '14 at 07:04 PM

Video shouldn't be necessary, but thanks for the offer!

I would also recommend trying 4.5, which was just released to the launcher.

You should be able to find your BSOD logs if you go to Control Panel->System->Advanced->Startup and Recovery Settings. It'll give you the directory that your BSOD logs are left in. I haven't looked through those crash logs personally, but it's possible they have relevant information in them.

avatar image Rhinosaur Oct 14 '14 at 07:26 PM

thanks, i will try 4.5 when i get home tonight and also check through the BSOD logs and upload if it still happens.

avatar image Rhinosaur Oct 15 '14 at 01:52 AM

i have tried v4.5 of the editor and i no longer BSOD. :) i'm so happy :)

Can you also try running some decently hardware taxing games? I've had, in the past, crashes occur due to sudden increases in power draw, on an aged power supply.

avatar image Rhinosaur Oct 15 '14 at 05:19 AM

power supply is new, and have been running star citizen/tf2/borderlands2/wildstar without major issue (as some are/were still in beta)

avatar image Rhinosaur Oct 15 '14 at 04:30 AM

Update: i was able to start a new 4.5 project (blueprint) and work for about an 1.5hrs and then my computer froze, and i was forced to push the reset button.

Now when i relaunch the editor, my computer freezes within 3-10 seconds after the editor load screen. and have to push the reset button. (all computer components were new when purchased in june '14) there are no errors for either a BSOD or in the ram going to see if my video card or CPU is the issue

avatar image Jonathan Dorman STAFF Oct 15 '14 at 07:26 PM

My assumption is that the hard reboot caused some file corruption - that's why you're having issues immediately when starting it up now. I would try using Verify (from the Launcher) on 4.5 to see if that fixes it.

Did you try Control+Alt+Delete before you reset your computer?

avatar image Rhinosaur Oct 15 '14 at 08:19 PM

i will try reverifying 4.5 tonight.

CTRL+ALT+DEL doesn't repsond. so it seems to be getting a hard lock, and can only reset with the button.

avatar image Jonathan Dorman STAFF Oct 15 '14 at 08:21 PM


If you find out that the problem is with your video card or CPU, let me know what kind you have.

avatar image Rhinosaur Oct 16 '14 at 04:23 AM

tried revarifying, it worked for a bit, and then i got the freezing again.

HOWEVER, i've narrowed down the problem to the video card. I installed my older MSI (Twin Frozr II) nvidia560Ti and the editor worked just fine with no freezing. i then installed my original ASUS (DirectCU II) nvidia gtx770 and the freezing comes back.attached is a photo alttext of the screen with the temp on the side of both the CPU and GPU. (more specifics on the video card are probably in the dxdiag.txt attached to the original post.)

avatar image Jonathan Dorman STAFF Oct 16 '14 at 02:16 PM

It's good that we know the problem is with the video card. We have some computers in the office using 770s and they don't have any freezing. Therefore, I'd recommend updating your drivers; it's possible that you just have an outdated driver for your 770 and that's the issue. If that doesn't fix it, then there may be a hardware defect with the card, which means you'd need to send it back to its manufacturer (if it's still under warranty).

avatar image Rhinosaur Oct 16 '14 at 05:33 PM

i've been running the latest drivers, i've even tried previous versions of drivers. so it's either a manufacturer defects or the corsair cx750M (750w) isn't enough power for the motherboard (P9X79 DELUXE - ASUS) and the video card. or a combination of both.

avatar image Jonathan Dorman STAFF Oct 16 '14 at 05:45 PM

A 750w power supply should be plenty for any reasonable computer. If you want to be sure, you could build your computer on pcpartpicker and see what your estimated power consumption is.

That said, it seems like it could be a manufacturer defect. You could send in an RMA request, or if you had access to another 770 you could try the editor with that installed.
