Is it a bad thing that I have to do a hard restart on my MBP almost every 5mins?

Of course it is.

Hard restarts can cause data corruption and directory damage.

Have you been able to start up and shut down without having to to a hard shutdown (you don't really do hard restarts)? If so, compare the boot time to those times when you've done a hard shutdown.

You'll probably find that booting up after a hard shutdown takes significantly longer than booting after a normal shutdown.
