Gray Screen with mouse pointer AFTER Apple logo

[Person123]

Hi all,
Installing ML onto my PC went fine, only I had to boot with -x PCIRootUID=0.
After installation, booting off the USB with -x PCIRootUID=0 Worked fine.
This morning upon attempt to start up the computer so I could install MultiBeast, After the apple logo with the gear, I just got a gray screen with my mouse pointer in the top left corner. (I couldn't move it)

I've tried using GraphicsEnabler=No and got nothing. Any Help??

My specs:
Mobo: ASUS P8B75-m/csm
Graphics Card: nVidia GeForce GTX550ti
Processor: Intel Core i5 @3.20Ghz Quad Core
Memory: 4gb (4 x 1gb)
PSU: 600w

try to safe boot - see if it gets you in. -x is the boot flag. I think the problem is graphics related. Have you been able to boot into the OS at all? Your card is natively recognized. GraphicEnabler=no fixed it for me.

Thanks for the reply, I did a re-install of ML off of my flash drive and that did it.
Turns out installing MB messed up a kext file I needed..

Even with MB installed, I gotta always boot in safemode.. Any fix to that?
