Laptop did not shut down properly

I closed my laptop before it could shut down properly last night. I noticed that the white light kept blinking so I opened it and found that it was stuck. I then forced it to shut down by pressing the power button. This morning I switched on my laptop and found that it actually had not been switched off and it was stuck. It responded a little when I clicked my browser, but then the whole thing just went into sleep mode. It wouldn't wake up so I hard reset it. But now my laptop just starts up with he Apple logo, goes to the startup blue screen and wouldn't load anymore. The cursor comes up and I can move it around. But after a few seconds it just goes to sleep. I can only wake it up if I press the power button for a long time until the light goes off then press it again for it to "wake up" to the blue screen. I tried resetting using Ctrl + Alt + P + R three times but it still goes back to the blue screen. I'm waiting for the battery to go out now, I have no idea what else to do!

This sort of happened before where it wouldn't wake up properly and I had to keep pressing the power button to wake it up. It would wake up for a while, load a couple pieces of my desktop then go to sleep. I kept doing that a few times until my desktop fully loaded and it started working again. But it doesn't seem to be the case now because all I'm getting is a blue screen!
