Half Life Black Screen

Crashing or Black Screen on Launch Issue – Fix

This has to do with an issue of hooking up a second monitor to your system, but no picture showing on the screen on one of your monitors. I’ve had this problem when setting up dual monitors before. I unplugged my second monitor and when I plugged it back in, the screen remained black. The solution is simple.
Half-Life: Alyx Blackscreen Problems (Radeon VII) I am experiencing frequent blackscreening while playing that doesn't seem to correlate with any specific gameplay actions. This doesn't happen in intervals but rather at random times leading me to believe this is a graphics card or driver issue.

Crash on Launch Issue

The first reason for the game to crash might be the lack of administrative rights. Right-click on the game’ and select “Run The Game as Administrator”. If this doesn’t work for you then try playing the game from the account that has the administrative rights.

I've been in a hiatus from playing HL1,because I played it up to the end of Apprehension. There was a black screen after the HECU beat me up,and it wouldn't load the next level. I waited up to 15 minutes and no screen/transition loaded. It was just black.

Another reason for the game to crash at launch is the anti-virus or the Windows Defender, which might be detecting the game’s exe file as a trojan virus.

You can either disable the anti-virus or make an exception for the game in the anti-virus. This will allow the game to run on your system.

Also, an outdated GPU driver might also be the reason for the game to crash. Just update your drivers to the latest version.

Black Screen Issue

Fix 1: Switch out of your game, then switch back in

This is the first thing you should try when you have a black screen issue on Half-Life: Alyx. To do this:

-When your game is running, press the Alt and Tab keys on your keyboard at the same time to switch out of the game.

-Press the Alt and Tab keys on your keyboard at the same time to switch back into your game.

If this works for you, you won’t see the black screen. But if the issue persists, don’t worry. There are still other fixes for you to try.
