Error when launching avd

I launched the AVD Manager with Android Studio 2.2.3 in order to run the avd Nexus 5X API 25 x86 and I got these errors :
emulator: WARNING: Crash service did not start

My computer has 4Gb of RAM. So what should I do to fix the errors ?

It seems that your VGA driver doesn't support OpenglES.
Turn this option off.

Android Emulator crashing with GLES 2.x config

My emulator used to run fine till yesterday but ever since I updated my Windows 10 and Android Studio, it has stopped. I tried updating the graphics driver but that is fine as well.
I did turn off the gpu but then my emulator runs very sluggishly. I checked many posts here regarding this and have found similar solutions.
Could you please help.

Open AVD Manager
Edit this AVD (the button is at the 'actions' column)
Emulated Performance，Graphics：Software-GLE 2.0
finish the configuration and restart your virtual device again
Select 'Software-GLE 2.0' for Graphics，not select 'Automatic' or 'Hardware-GLE 2.0' (emulate graphics in software)

Android Studio emulator could not find wglgetextensionsstringarb

When I try to start the emulator, suddenly I started getting this error
everything worked couple of days ago.
if I disable GPU acceleration then it works but very slowly.
I tried re-enabling virtualization in the bios and it worked once and now I get the same error again..
I have the latest android studio 2.2.1
I have a new graphics card GeForce.
this is the error message
Hax is enabled

SOLVED IT!
it seems to be a screen resolution issue.
I have a 4K laptop but I use 2 regular large screens and the laptop screen if off (lid closed). it seems that my graphics cards detects this and switches to the on board shitty intel card.
the solution is:
open laptop lid (so the laptop screen will be on)
start emulator
once the emulator is running, you can close the laptop lid
or use your graphics cards settings to enable hardware GPU always for AVD (if possible)

Projects doesn't load in the android studio emulator

I am using Android Studio 2.1.3.My emulator works perfectly, show inbuilt apps etc but does not show the projects I created.To check whether it was by a mistake that I made,I just ran a simple hello world app but still it does not show up on the emulator.
These messages come on the bottom panel under AVD:

How can I resolve it?

Android Studio 2.1.1 emulator error

I am learning the basics of Android programming. I tried to emulate my test app and got following error. I am emulating using API 23, Android 6.0 ( Marshmallow) and getting the same error when emulating for Nexus 5 or 4. what should I do?
Error Message:

Changing the 'Graphics' option to "Software- GLES 2.0" has worked for me.
