When waking my computer it won't come back up from black. Force the computer to shut down, and when I try restarting it, it will flash white and then won't boot up. Tried resetting PRAM and SMC, doesn't fix it. Tried booting into recovery or diagnostics, nothing will boot. This happens frequently, eventually it will work again, how can I get it to boot, and is there a way to fix it so it won't happen any more?

MacBook Pro, OS X Mountain Lion (10.8.4)
