My Mac Pro is having significant issues on start up (will not boot-up) The harddrive and/or fan sounds like it is racing as soon as the power button is pressed.  In order to get the computer to boot, I have to cycle the power up/off process 5-8 times.

 

I have also noticed in the last 24 hours that when the computer goes to sleep, it sounds like the hard drive and/or fan goes into overdive until it is woke from sleep mode.

 

I would be very grateful for any guidance.
