Freezes at Apple symbol then reboots
MacBook Pro (early or late 2011) 15". Sorry I can't tell you for sure as it won't boot up. When computer was working, all of a sudden I got a lot of tiling, then it appeared to fix itself and within minutes it turned black like going into sleep mode. I did a hard boot, then got a gray screen with the Apple symbol with lines that were uneven. It has a "loading" line under the Apple but only gets about ⅔ of the way, freezes/stalls, then goes full gray with no lines for a time, then goes black to reboot. I hear it booting up, but it keeps doing the same thing. I have tried the Cmd-S until it said 'hard drive appears to be ok.' Same thing. Then I tried the Cmd-R, Ctl-Opt-P-R-power, and Ctl-Opt-R to no avail. Does anyone have any suggestions? I certainly can't afford to take it to Apple. :) Thank you!
Is this a good question?
