CAN'T EVEN LOG IN TO TABLET

I have a generic Android 4.4 OS tablet. I got this popup display" unfortunately, YouTube has stopped working". So I just shut it down to reboot it. Now, this same message appears on my tablet when it powers back up and I CAN'T EVEN LOG IN so that I can do a factory reset. I keep hitting OK but it pops right back up. What can I do? It won't go away!

Thanks. I figured out how to do the hard reset using the power and volume buttons, but now I can't set up my Google account on it. I keep getting "couldn't sign in, there was a problem communicating with Google servers. Try again later". Well, that is 2 hours now that I have been trying. When I go to Apps in Settings, Google Play Store is grayed out in the Force Stop and Disable areas at the top. Don't know why or how to fix it. Plus I don't even see a Google Play Services App included in the list. This is all I can tell you about the tablet itself.

There is no such thing on this tablet that I can find - neither disabled nor turned off. When I go to "running" apps, it lists Google Play Store as running. How can it be listed in the "running" apps, but under "all" be grayed out? When I did the factory reset, (3 times today now), any apps that would have been turned off or disabled should have come back as normal, shouldn't they?

I just tried signing into my Google account from the web browser on the tablet and had no problem. So what is configured wrong on the tablet that I can't set up my account on it in settings?

Where do I turn it on in AM? I don't see any AM listed on the tablet. I've looked through my account online but don't see anything for auto-sync. Also, my google acct is not on the tablet, that's the whole problem! I keep getting "couldn't sign in, there was a problem communicating with Google servers. Try again later".

well, it didn't work for my tablet. It's just a piece of s_ _t!
