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!

Hold down "SHIFT" when turning on the computer.

Does it start in "Safe" mode?

No, it does not start in safe mode.

When trying to boot up in safe mode, the progress bar goes a little farther, but then goes to gray screen again. I've tried the hardware test and that came back saying there were no hardware problems. Besides this and the Cmd-S then /sbin/fsck -fy until it stated the hard drive appears to be ok, nothing else has worked. Should I try the other command listed under that one? Maybe I'm missing another 'power on' command that I could do? In addition to the ones listed above, I have tried the Cmd-Opt-R (I think that is what I meant above, but it says Ctl (??)), and the Ctr-Opt-Shift-power for 10 seconds and then power on to no avail.

The GPU has failed. This was a well know issue and caused a class action law suit against Apple which resulted in a short period repair program which has now expired. https://www.apple.com/support/macbookpro...

Outside of replacing the logic board, possibly Louis Rossman may be doing a board level repair.
