@TaaRt’s, advice is the best bet.
However I’ll go ahead and give my preliminary and anecdotal advice. For future debuggers that may stumble across this thread, I’ll assume you are a technical novice.
The screen blacking out sounds a bit concerning as that may be a hardware issue, however try these solutions first:
A lack of storage space, this personally has caused Blender to crash on launch for me in the past.
How much hard drive space do you have left? I personally have experienced some technical difficulty when Windows silently downloaded an update leaving 4MB of space. If it is essentially zero; this may be a source of problem.
Assuming Windows 10, go to My Files (Win + E)>This PC>Device and drives>Windows (C:)
If this shows as red, you most likely are running into storage issues and should look into either expanding this or uninstalling unnecessary programs.
Insufficient RAM when launching a Blender file.
Are you running out of RAM? This could occur if you have an older machine and are running multiple programs in the background such as 20 tabs of Google Chrome (or one). This is a horrible habit of mine to the point I’m idling at 7.6GB out of 24GB; however most family desktops only have 4GB or 8GB.
To diagnose this, you’ll need to open up Task Manager.
Assuming Windows 10, go to the Task Manager (Ctrl + Shift + Esc)>Performance Tab>Memory
If you don’t see any tabs, click “More details” in the bottom left corner.
You’ll want to do this with your normal amount of background activity.
Conflicting device drivers causing a crash.
Make sure your drivers are up to date, something could be botched up causing an unexpected crash. This is a more specialized solution, so I’ll just provide the official Windows documentation for that.
The old reliable debugging techniques.
- Have you tried restarting your computer, or reinstalling Blender?
- Is the connection on your monitor secure (may cause black outs of display with vibration) and is it connected to your graphics card instead of your motherboard?
- Have you tried updating Blender to a newer version or downgrading to an older version?
If do you find any solution, be sure to post what it was. Good luck!
