Why my Android emulator does not start?

I don't know why but the Android Emulator doesn't want to start. After the text ANDROID appears, without the 3 points, after a period it stops as it is ready to go, but each time starts again to load.

How can I see if returned an error, or my computer configuration is the fault?

Thanks.

More info:

I received the following warning:

WARN/SharedBufferStack(166): waitForCondition(LockCondition) tim开发者_如何学Pythoned out (identity=1, status=0). CPU may be pegged. trying again.

And application seems to be stuck here. The same warning appears for several times.

You should try creating a new emulator instance.

Are you providing your own system.img or are you using the default one? If your own, perhaps it has a problem in it.

You might try selecting the "wipe user data" box to be sure nothing you've installed into the image is causing the problem.

1. It takes much time to start up emulator (max 3min).
2. If you get some errors you'll see them in logcat.
3. Try to create new emulator instance.
