How come my mini iPad is not working after trying to update apps?

Question

My mini iPad is repeatedly showing me a black screen with a, "white apple," in the middle & then a couple of minutes later it turns off for a few minutes. Then the black screen with the, "white apple," in the middle comes back on again and then it goes black again. Sometimes the black screen would lighten and the whole pattern of these "screens" would start over again. It's been doing this for hours since I fell asleep.
This happened when I was trying to update 4-5 apps at the same time. It had trouble updating the, "Pinterest app." It failed once and I retried it and that's when my mini ipad started to not work. I can't use it at all. I never had trouble updating several apps at one time before. I was at home using my wifi and my wifi strength was at its maximum for the iPad.
The battery was at 40 something%, so I charged it over night. It has the latest iOS update software. I had downloaded that yesterday.
I plugged it into iTunes on my computer and the same thing is happening. It's picking up my icloud stuff like my music and videos and my computer is trying to import photos from my mini ipad automatically, but my iPad isn't fully recognizable on iTunes. I get 2 error messages. One says, "iTunes was unable to load data class information from Sync Services. Reconnect or try again later." I also get an error when trying to import photos (just to try it out). The other error message says, "The iPad cannot be sync because this iPad cannot be found."
And so, I unplugged it and plugged it back in and I get the same response. My iTunes is the latest version.
I don't have warranty on this iPad and I spent like $500 on this one. I'm kinda worried...?
Any kind of response would be appreciated....

First, try a system reset although I can't give you any confidence.  It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.
