Dude, your using a chrome book those "computers" if you can even call them one are not meant to be used for much. However the best and most stable way to use it is to do the fallowing.
1. Wipe the 32gb Drive
2. Install Linux Mint (or Ubuntu)
3. Purchase an 128gb SD card If it has a SD card reader or a Flash Drive instead if it doesn't
4. Enjoy your usable now descent computer
If your worried about compatibility don't at least for Linux Mint I've installed it on a few chrome books recently it works well and is much more productive than on a ChromeOS
