I have a Macbook Pro early 2011 that is stalling at bootup

Customer Question

Hi Pearl - I have a Macbook Pro early 2011 that is stalling at bootup this morning. It crashed a couple of times yesterday but recovered and shut down normally last night. This morning it has restarted itself several times and is now frozen with the progress bar about 60% complete.
JA: Fortunately, the wizards we work with know the MacBook inside and out, and it would be my pleasure to connect you with the best person for the job. Is there anything else the Mac Technician should be aware of?
Customer: I've noticed lately the fans come on a bit more often, even when the required
processing is not heavy. - Malcolm
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Mac Technician about your situation and then connect you two.

We can run Disk Utility and see if it works or not. Turn off your Mac by holding down Power button for 10 seconds. Then turn it back on and immediately hold down Command and R keys at same time for 20 seconds and this will boot your Mac to the Mac OS X Utilities screen. From there, click Disk Utility. Select your hard disk at left column (Macintosh HD or hard disk name). Then click Verify Disk (under First Aid). If asked to repair, click Repair Disk. Then click Repair Permission.

If you are using latest Mac OS X El Capitan, then you will not see Repair Disk option in Disk Utility. Instead click First Aid button and run it. Repair if asked.

Then restart from Apple menu. If that didn't work, then turn it off. Turn it back on and immediately hold down Command, Option, P and R keys at the same time for 5 seconds, then release the keys and immediately hold down Shift key for 20 seconds. Does it boot into desktop ?

Please let me know if that didn't work, so we can continue troubleshooting.
