MacBook pro - only wakes up or restarts from disc

Can not wake up my MacBook pro once it goes to sleep, or restart it without the installation disc. The apple logo appears but then the screen goes white. It DOES restart if I insert the original OS X installation disc. The fan is running really fast and the computer gets very hot..

Running OS10 version 10.9.5, Processor 2 GHz Intel core 17. 264 GB free out of 499

MacBook Pro (15-inch Early 2011), OS X Mavericks (10.9.5)

Run an Apple Hardware Test:

Note an error free AHT is not definitive.
