Android Emulator stopped working

For some reason my emulator isn't working (even though it previously worked just fine). The emulator launches but my app doesn't. The errors are:
emulator: WARNING: VM heap size set below hardware specified minimum of 256MB
emulator: WARNING: Setting VM heap size to 384MB
emulator: WARNING: Classic qemu does not support SMP. The hw.cpu.ncore option from your config file is ignored.
emulator: device fd:1140
HAXM is not working and emulator runs in emulation mode
emulator: HAXM does not have enough memory remaining to load this AVD.
emulator: AVD RAM size = 1536 MB
emulator: HAXM max RAM size = 512 MB (for all running AVDs)
emulator: Try creating an AVD that requires less RAM or re-running the HAXM installer to set a higher memory limit. The HAXM installer may be found at ....
emulator: Failed to get Hax capability:6
It was working fine (app and everything launched), but these errors appeared about today. How can I fix it?

image here Android Emulator Firstly run,but after some seconds its automatically stopped.
To Fix this problem you need to graphics driver installation of your computer.

HAXM is not working and emulator runs in emulation mode (Unable to set memory on HAXM settings beyond 978 MB)

When i am trying to adjust the memory from AVD manager it adjusts as per my settings entered but on running the emulator system resets the memory of emulator to 1GB
If i try to adjust memory from HAXM it doesn't allow memory setting above 798MB

You can't set more than 768MB for HAXM. See documentation → Tips and Tricks,
When creating the image it is not recommended to set the “Device ram size” larger than 768 MB.

well, as it says you need to reduce your AVD Ram size, You could edit it in your AVD Manager.
Or you may use some third party emulators too, My favourite Android Emulator for app testing is 'Genymotion' you may choose a free licenses for personal use.

Android Studio Running app is too late

i have a problem when i am trying to run my app with a emulator that its 2 hours and it didn't started until now
and this message was printed
emulator: device fd:892

I guess you said '2 hours' with exaggeration.
First 1536 MB Ram for an emulator is too much. You can reduce it to 512 or lower. Also I suggest you to use GenyMotion which is more faster and useful than standard android emulator (at least it my i3 device).
Using GenyMotion, I'm creating 320x480, Jell Bean emulator with 512 MB RAM in 1-2 minutes.

When you create an emulator using the AVD choose advanced settings and change the RAM to 1536MB. or just edit you current device the same way.

Android studio: AVD ram size not changing?

I am using Android Studio 1.3.2. When I run the app, I get the following event log:
f:\Users\User\AppData\Local\Android\sdk\tools\emulator.exe -avd Nexus_One_API_23 -netspeed full -netdelay none

I've already tried increasing the RAM size of AVD Nexus One to 512 MB and 768 MB. The same event log occurs for both.

You can downgrade the Intel x86 Atom System Image to API-19 instead of API 21/22/23 so as to use less RAM space. You can find the config in the config.ini file, and set the RAM size to 512 by hw.ramSize=512.
I had tried Image with API-21/22/23. Even I had set ramSize=256 in config.ini, or add option to change the memory size, after the command: emulator -memory 256 -avd [<avd_name>], it still shows: emulator: WARNING: Increasing RAM size to 1GB
