Hello, I’m using 4.17 and 4.18 no matter which scene is open it can freeze entire PC and nothing is happening, it just doesn’t move and never saving the file or any auto backup. Complete hard crash, not even Blue-Screen, I cannot track the problem due to inability to save anything.
I thought it’s Nvidia drivers, I have installed an old driver from September, 385 remove all Nvidia stuff, unfortunately, it did not help.Then I installed the most recent (388.13),
how to fix the problem? Is there any way to find the cause of the freeze?
Yes I was using it since version 4.9 everything was okay,
my set up is pretty usual, Win10, Nvidia 1080, SSD1TB, 64GbRAM (3000Mhz) and Intel i7-6700 4Ghz.
I still working, but I have 3-5 freezes day, then I hard resetingand working for another 1min-3hours and then Freez Hard resent and keep working. Scene can be complete new or empty, it happening only while I fly over the scene, FLY - is the problem probably.
I did reported there few times, no one has replied. I also noticed answer hub is useless for many questions, the chance to get the reply there is very low and msot of the time just a waste of time posting there.
It is still happening, I have 3-8 freezes a day, I quickly reset PC unpluging it from the power and plugin back, this is how I work now. Today it has freezed once I was saved the material. It can happen any time while I work in UE, but never happen anywhere outside UE4, so I assume this bug started to exist in the newer UE4.17.2 and UE.18.1 still there
I had similar issues on my older computer (Geforce 770) and found a bug while searching online. Apparently there are several Nvidia cards that have this issue and Epic is investigating. I lost about 10 hours of work before I decided to upgrade. Now I have a 1070 and no issues so far.
Suggestion: Try changing to an older Nvidia driver for your GPU and see if it makes a difference. In my case, going back a few months made things better.
CoquiGames Thanks for the advice! I will try to move to 6 month back driver.I still have few freezes a day; I noticed they are mostly while I calculate the shader either in the material editor or viewport it stuck when it’s starting to calculate it. I will report how is going next week.
Moved entire projects to HDD from SSD, did not help
InstsalledNvidia Driver from June 2017 (now is November 2017) and it did not help
Noticed it is only happening while it calculates the shaders, after a fresh restart, it still freezing if it starts to compute the shaders.
Decided to do the project on the other machine, currently looking for the computer to work.
Only happening in Unreal Engine 4 V.4.17.2 and newest, maybe I won’t be able to use my machine anymore for developing the projects if this bug will exist since now.
It sounds like you have a conflict of sorts. I re installed 4.17.2 last week on win 10 and linux mint everything is working. I had a ram leak that was due to a bad bp. It would continue crashing until i deleted the other bp’s that were trying to ref them. Maybe try a linux build it would at least tell u if your having issues with windows. Linux turns grey when compiling shaders. Just a warning. It can at least tell you if its something hardware related.
yesterday I damaged the project due to UE4 freezes my pc while doing some shader calculations. I lost entire light bake and for some reason all cinematics scenes has lost their content inside, they weren’t even connected between each other. Problem still exists, I don’t even know about full reinstall of Windows 10, becuase it seems like they did some bug and no update would help it.
Brand new Windows 10 on a brand new hard drive, did not work, I’m distraught, I think this is a glitch only of the unreal engine, not Windows nor Nvidia drivers.
Since I have tested it all, googling prior problems from other users telling me UE4 has to be fixed, Unfortunately, I 'm only the victim now of my laptop’s configuration, and I cannot work in UE anymore until they are going to fix a glitch which I cannot even track due to hard freezes. Thanks
It’s probably not UE4, otherwise there would be many more people having the same issue. I would run a Windows memory test and see if there might be something wrong with your RAM
I know it doesn’t make sense, but it is only happening inside Unreal Engine and just in version 4.18. I am going to do memtest for sure. Overall I’ve read many articles about common problems in Unreal Engine and freezing entire PC, not just crash but freezing and then hard reset.
Does this freeze your entire PC? Your clock won’t update and your mouse cursor won’t move? I have a similar issue but it is few and far between, usually happens if I leave UE4 open for >45 minutes to an hour. I’ve just been saving my work repeatedly and making sure to commit code changes in case it freezes. I’ve found that restarting UE4 every half hour or so to seem to avoid the problem, but obviously this is not a solution and sometimes building light can take that long.
This never happened when I was using anything below 4.18, skipped 4.16-4.17 so I’m not sure what’s going on. My PC specs are:
CPU: AMD FX-8350
RAM: 16GB
GPU: GTX 970
EDIT: Are you doing your project in C++ or blueprint? I wonder if Visual Studio might have anything to do with it?
I have laptop Sky X9E2 (i7-6700, 1080Geforce, 64GB RAM, SSD) and Windows 10 PRO, my laptop just stops responding and freezes the screen for 30 sec and then changing colour to random (pink, yellow, red) and then just stays like this for hours until I hard reset it. It mostly happens when I work in the material editor, but sometimes after freezing I restart and run UE again, and it freezes in the first 15 sec, I don’t know why, I can’t even track anything, I restarted my PC yesterday with fresh hard drive, and today it occurred again. The only suspicious thing that left is a RAM. I have 64GB 3000Ghz speed on ram, it very fast in comparison to 2400 that was there by default. I changed my BIOS settings in summer. I had a couple of freezes there, but then I swap them in order and it was working fine. But this is maybe the problem. I had not tested it yet if it’s going to happen again I going to lower the speed to 2400 back as it was by manufacture when I got my laptop. It’s okay, but compare to 3000 for some reason I have noticed significant speed overall in the system, everything just flies. Did you touch any RAM or BIOS clocks?
Have you messed with the TDR settings in the registry? I’m pretty sure that can cause a hard-lock if they are incorrectly modified from the default settings. Look up TDR Manipulator and within that program, you should be able to reset things back to the Windows defaults.
Strange, my issue is just that my PC will freeze entirely, and I have to reset it but I don’t get the weird graphics problem you see on your display.
I think our common denominator is the Nvidia GPU. Although mine is the 970 and yours is the 1080, something must be up with the drivers they both use. I wonder if anyone with an AMD GPU has had the problems we have had?
I recommend restarting Unreal every 20-30 minutes to be safe and see if that avoids the issue at all. For some reason it works for me, which to me could indicate some kind of memory leak (or VRAM leak perhaps?).
EDIT: Something I just thought of is that this seems to happen a lot after doing hot reloads (compiling code) and also building lighting only, not the entire project. Does this happen to you primarily after either of those things? If I’m not doing anything I seem to be able to keep the editor open indefinitely, although my GPU doesn’t quite like that!
EDIT 2: Also, what are you keeping open while working on your project in UE4? I keep VS, Github Desktop and Opera open while I’m watching the videos on Udemy. I’m beginning to think it would be a good idea to keep Opera closed and only watch the videos on my phone through the app.
