Grey screen after installing new ram

[prach138]

I have a late 2011 macbook pro, specs are:
10.7.5
2.4 ghz intel core i7
4gb 1333 Mhz DDR3
15.4 inch hd graphics 3000 384 mb

I received my corsair 16gb upgrade kit today and installed it with little difficulty. I booted the comp and everything was fine, the ram was recognized. After playing a few games I downloaded a program for Gamepad mapping, I think it was this one:

https://www.macupdate.com/app/mac/17779/controllermate

After installing the program I was prompted to restart the mbp as the finalization of the process, which I did. My mbp has yet to completely boot now, staying only at the grey screen With the spinning load animation. I've tried safe mode, I see a loading progress bar that gets about a little short of half full and then it disappears and I'm at the perpetual grey screen again.


I re-installed the old ram and nothing is different. I really do not know what to do, this mbp really doesn't have a lot of mileage on it, it was barely used by my father before he passed it on to me about a month ago.

I would greatly appreciate any advice that can be spared. Thank you.

Hi Vincent, first thing is i would take out the RAM again and reinstall it, making sure its seated correctly.
2nd, if you have a backup and its a Bootable backup, from SuperDuper or Carbon Copy Cloner, then boot into that, and then run repair permissions from Disk Utility.
If you don't have a backup, then try resetting the PRAM/VRAM follow instructions from Here or rest SMC following this and if all that fails, come on back.

I have that App you linked to, and works fine on my 13" MBP running Mavericks, its just a coincidence this has happened now.

Cheers

Seems to me that the trouble has nothing to do with the ram...but the install of the app mentioned above.

Try two things:

1. Booting into "Safe Mode":
OS X: What is Safe Boot, Safe Mode?

2. Booting the computer from an external HD with an OS installed on it.

In either case...try to uninstall that app (or at least disable it). If this cannot be done...you may be looking at a complete OS reinstall.

If you do not have a Backup, since you have Lion try this and boot into the recovery partition and run Disk Utility from there and repair permissions.

Report back if you would.

Thanks for all of your quick replies guys. I ended up reformatting (then upgrading to Mavericks). It was something that I was planning on doing, but avoiding as I was trying to finish an editing project.


Anyways, thanks!!!
