How do I determine the cause of a crash? I get no crash file. I updated my graphics driver recently (NVIDIA GTX 1650 SUPER). It happens about a minute after I switch from displaying in Solid Mode to Material Mode (or to Render Mode, but takes longer). I never see my scene in material mode. Objects turn white immediately and stay that way. Blender memory usage starts out less than 1G, then slowly rises to about 12G (out of my 16G), then slowly bounces around down to around 3.5G then crashes. I started Blender from the command line with --factory-startup --debug-all. Since there was no crash file, I trapped the console output, although it may be useless, except perhaps the last line. It can be seen  (1.5MB). The file that caused the crash is  (19MB).

It would be useful to know where Blender log files are stored on Mac, Linux, and Windows. It could help with troubleshooting crashes and other issues.

For the past two weeks, I've been getting this BSOD error on my Lenovo laptop. I have even reset my laptop ("rest this PC"), but it's still happening.  My laptop details:     I have the latest Nvidia driver for my Nvidia Geforce MX150: 431.60 released on 23 Jul 2019.  I have the latest BIOS for my laptop: 8TCN53WW15  released on 15 Jul 2019.     I have run WhoCrashed, it says it says the problem was caused by some driver which could not be identified. If I get to know the problematic driver I will update/uninstall it.  How can I analyze my dump files, so that I can find the problematic driver?  Edit 1: If you get "Oops there was a problem with the network" on google drive page while accessing dump files, just click on download. They will be downloaded. I don't know what's causing this.

Update  This has been confirmed resolved in a later version 376.33 and possibly the update prior.     Okay, I recently did a computer update. I used to run Blender 2.77 on a Dell desktop (5 GB RAM, 2.7 GHZ, Windows 8, build in graphics card). Since that computer wasn't fast enough for my preference, I saved up and got a new gaming laptop - the Asus ROG GL552 (Windows 10, 16 GB DDR4 RAM, Nvidia GeForce GTX 960M with 4 GB DDR5 RAM, 2.6-3.5 Ghz, and quad-core intel processor). That laptop has been known to have outdated drivers, so when I got it, I updated it to up to date Windows 10 drivers.  As soon as I started Blender, I immediately noticed its speed. Even doing simple things, like clicking buttons, or rotating the view with the middle mouse button, took too long to register in the program. I tried changing some User Preference System settings, but that didn't really help much. And the hardware seems to be fine - the render is lightning fast (renders the startup scene in under .1 second; it's just laggy when loading the uv screen), so I don't know why it's like this, or what to do. Also, I ran Blender 2.77 on this computer, and it was also slow (although it was fine on my previous computer).  It could be an issue with drivers perhaps (or maybe OpenGL?), but I ran Unreal Engine 4, and had none of the same issues - the speed was pretty decent on that; so I'm not sure why Blender would be so slow. Any help is appreciated - thanks guys!

Until now until Blender 2.83.4 my GPU NVIDIA GeForce GTX TITAN X 12288 MB is recognized via CUDA. With Blender 2.90 and Blender 2.90.1 no GPU is seen, also not under CUDA. What is wrong? I'am therefor still working with 2.83.4 My computer Mac Pro (mid 2012) 2 x 3,46 GHz 6-Core Intel Xeon / 96 GB 1333 MHz DDR3 - Mac OS High Sierra 10.13.6

When I render my image, it stops, giving the error message "CUDA ERROR: Launch failed in cuCtxSynchronize() Line 1372", then when I try to start the render again, I get the error message "cuCtxCreate: Launch failed"  all the answers I have seen say to update your graphics card driver, however, mine is up to date. I have a GTX1080 with 4gb of RAM.

so I'm working on a little bathroom scene and wanted to make a clay render. I started looking for the material override which I kinda knew where it was and on the way I switched my render engine accidently to workbench instead of cycles. Switched to cycles all my seetings on the render tab are missing except color management and free style. Hows that? I restarted blender multiple times and tried some other stuff but nothing changed a thing, and I'd rather avoid a new installation

Blender has just purged the entire game engine from 2.8. There is no "Game Engine" mode anymore and there isn't even a logic editor. I tried installing a GitHub Blender release with the game engine mode working but it failed to install because all the game code was gutted. Does this mean that Blender 2.8 is going to lose the game engine, or is the game engine just being redone for better compatibility and whatnot?

I'm working in the new 2.8 with someone else's file (made in a previous version of Blender), and I can't get the textures showing in the viewport. I've relinked all of them to the correct location on my computer and Blender can seem to find them, but just won't display them in the viewport. I've made sure I'm in LookDev mode, and also added a lamp, but still nothing.  In 2.79, it was always just a matter of finding missing files and that's it... Can anyone see what I'm doing wrong here?  Thanks!

I was experimenting with a file in 2.8 and accidentally saved it. When I opened it back in 2.79 I can't see my model. It disappeared with the error  File written by newer Blender binary.  How can I get my model? I can see my model in 2.8 but nothing in 2.79. I tried to export it  in .obj, but I lost all my modifiers, material and camera setting.

I went to animate a project, Blender was returning a blank screen.  I have attempted to restart both Blender and my laptop, as well as re-downloading the program.  With each attempt, Blender exported a black movie, which I attempted to watch multiple times.  I even attempted to reanimate one of my older Blender files, and even that reexported as a black movie.  I have attached a picture of what I see when I render. Please Help! Thank you!😀

Is it possible to render an image and have blender remember it, so that next time I open the file the render result will not be blank?  I am not talking about saving to an external file.  Specifically I would like to render an image, close blender, and come back later and be able to do some compositing on the render without having to waste a half an hour rendering it again (my GPU drivers are messed up so I have to use the CPU).  Currently the render result is blank when ever I open a file.

Blender is rendering an older version of my project, not the most recent one. I have made it using the Blender Render but it does not want to render in cycles either. A black and grey screen is rendered as if everything is transparent. Checked general camera, lighting and compute devises in case I messed something up but I can't find anything. All my textures and objects look normal, does anybody know what is wrong or what to check?  Ok added link:

I have read  and tried to follow the selected answer's advice. I have also read  but the second question I believe is unrelated to my issue. (But I'm not sure.)  When Ubuntu (Or possibly just Unity) crashes everything stops working. I have to completely turn the machine on and off. I cannot do the SysReq soft-reboot because I have not been able to find a key-equivalent for my keyboard/laptop model.   I can provide logs upon request, but to be honest I don't know which ones would be of use, or how much of those logs would be of use.   My computer is a Dell Inspiron 11 3000 series. I believe  is my model, assumed after cross-checking system specs with the listing I linked. The PC is running the newest LTS release of Ubuntu 14.04 Trusty Tahr.   At first I believed this to be a problem that only occurred during video playback, but while the system doesn't crash near as often when not playing back video, it still will occasionally.   I'm a software engineer, so I HAVE to have a reliable computer. I've recently decided to open-source all of my company's non-client-specific code, and changed all of my servers to Debian, and also installed Ubuntu on my main workstation. The company now uses 100% open source software on all of its machines. However, I will be forced to return to Windows if I can't resolve this issue, and I would really be bummed about that.    What are the steps, in plain language for an Ubuntu novice, of diagnosing crashes on Ubuntu? Once discovered, what resources can I use to fix these issues? And finally, is there a chance that I will be forced to use proprietary software in order to correct these issues?    Thanks.

I have an older Nvidia video card and my PC crashes when installing the driver for the video card in Ubuntu 16.04. When I get to the login screen but no further: after entering my password, the system went into a loop and returned always back to the login screen [with funny stripes present].   How do I fix this problem?

This is probably a silly question but I need some help. I opened a file that I've been working on for about a month in the new 2.8 version of Blender. However when I tried to reopen the file in version 2.79, the scene is completely empty. Here is where the problem lies for me, I accidentally saved over the original file save while in version 2.8 . Please help. Thanks!

This questions has already been asked a million times, but nothing solved my issue so far.  Situation   I'm using Blender 2.72b.  I'm not using nodes, just the plain old vanilla settings. But apparently I messed them up somehow. I'm using the Mirror modifier. I'm completely new to blender (and 3D modelling in general) and use it for a couple of days now. I deleted the cube and made this model from scratch (no import).   In texture view everything looks fine:   In material view (and after rendering) everything is black:   Attempts to solve   I have a light source. I have a camera. I have no ceiling. I have a material. I have a texture. Shadows are activated. I tried using nodes and my output was well connected - no change, still black, so I stopped using nodes again (I had no idea what I was doing anyway). I checked out many solutions posted on the web.   As my last attempt, I opened the vanilla start-up file again. Everything works fine with the cube. So I compared the material und texture settings step by step. It all seems the same. This topic is so extraordinary complex and I'm so bloody inexperienced that I'm stuck at this point.

Before I start, YES, I have done my own research - I know how annoying a repeat question is. Yet each answer is so specific to others...  When I tried the beta 2.8 64 bit, it says "Blender requires a driver with at least OpenGL 3.3 support. The program will now close."    The question: I know that it is true that 2.8 requires OpenGL 3.3. But does my PC not have it, doesn't support it, or do I have it and blender won't detect it? I'm not sure what info to include or what to look for, so here's my PC's specs:  Windows 10 (64 bit) Core -        Intel Core i5-2400 CPU @ 3.10GHz RAM -         8GB (7.89GB usable) System type - 64-bit Operating System, x64-based processor  Thanks!
