MacBook Pro won't work

I have macOS Sierra version 10.12.5

When I switch it On its start well, but after 5 mins all opened applications start send Error (Unexpected close). Even trying to open Safari, software update, iPhoto, Microsoft and a few others, all that happens is that the icon bounce up and down on the doc for about 3 minutes then stop with out showing an arrow under it and without opining the app. What should I do?

Reset SMC by following the directions applicable to your MacBook Air here ➔ How to Reset SMC. If that does not solve things then-
Reset NVRAM/PRAM by following the directions applicable to your MacBook Air here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.
