Answer 1

Have you tried enabling hyper-virtualization from your BIOS?

1. It's important to check if you have at least 2GB of HDD space before starting it, usually, it turns to boot up slower if you are using a PC with less than 16 GB of RAM for this new Studio 4.0. Check out this link for more info.
2. Also, check the amount of memory allocated to the Emulator, it should be probably higher than 512MB for a better experience.
3. Also, check the amount of memory allocated to the android studio by doing: File -> Settings->Appearance & Behavior->Appearance. In my case, a 6GB works just fine.
