Restarts twice with black screen

Question

Ever since I updated my brand new Macbook Pro to Yosemite, I've been having this really annoying restart issue. When I do have to restart my Mac, or when I choose to, it'll get to this black screen with multiple languages. It says, Your computer restarted because of a problem...
Funny thing is it goes to this screen after restarting initially, then it restarts again right after (after showing the black error screen)! Anyone else getting this? I only read that it might be an App or plug-in causing this that's incompatible with Yosemite? The only plug-ins I really have are Magic Keys and Secrets.
Should I run a Diagnostics or Hardware test?

Hello there Meg4Roney,
It sounds like your computer is restarting unexpectedly with a message saying that it restarted because of a problem. I would use the troubleshooting from the following article to help determine the underlying issue here:
OS X Mavericks: If your Mac restarts and a message appears
The most likely cause is faulty software. A kernel panic can also be caused by damaged or incompatible hardware, including external devices attached to your Mac.
Note: To print these instructions, open the Help Viewer’s Action pop-up menu (looks like a gear), then choose Print.
If the kernel panic is caused by a known problem, the faulty software is identified. To make sure that this software doesn’t continue to cause kernel panics, move it to the Trash.If the faulty software is not identified and your Mac continues to experience kernel panics, follow the troubleshooting steps below.
Restart the Mac in safe mode. If the Mac successfully starts up in safe mode, choose Apple menu > Software Update, then download and install any updates available for your Mac.Start up in safe mode
Uninstall any plug-ins or other enhancement software from manufacturers other than Apple. If you recently updated OS X or an app, plug-ins and other software that worked in the past may no longer be compatible. Read the manufacturer’s documentation (including Read Me notes) to be sure the software is compatible with your version of OS X.
Reset parameter random-access memory (PRAM).Reset your computer’s PRAM
Apple Support article: Mac OS X: What’s stored in PRAM?
Use Disk Utility to repair your startup disk or your disk permissions, or both.
Disconnect all USB and FireWire devices, except for the Apple keyboard and mouse. Remove hardware upgrades from other manufacturers, such as random–access memory (RAM) and Peripheral Component Interconnect cards. Then try restarting your Mac.If this resolves the issue, reconnect one device at a time, restarting your Mac after reconnecting each one, until you determine which device is causing the problem.
Use Apple Diagnostics or Apple Hardware Test. These apps can tell you if hardware you installed, such as additional memory, is incompatible, improperly installed, or defective.Use Apple Diagnostics or Apple Hardware Test
If the steps above don’t help, try reinstalling OS X.Reinstall OS X
Note: If you moved or renamed an OS X system file or folder, you must reinstall OS X. It won’t work to just replace or rename the specific item.
Thank you for using Apple Support Communities.
Take care,
