I have a bootcamp partition on a separate drive, so I tried to boot to that. Windows BSODs with a error of "trying to reset video card driver failed" Sigh. Looks like the video chip gone.

May also be resolved by
- Repairing the disk
- deleting your /System/Library/Extensions/BootCache.kext file and letting it be recreated slowly during startup.
This is dependent on what Disk Utility says.

Thanks. My system drive doesn't have a repair partition on it (cloned it from another source) so first thing I'm going tonight is building a repair flash drive and repairing the disk. If I do get it back up, i'll delete the boot cache kext see what effect that has.
If it's not hardware, why would Windows fail to boot complaining of video related issues and blue lines on the boot selection screen? Windows is on a separate physical disk and boot manager should be rom. Seems odd to me.

Got home, plugged it up and turned it on and behold it worked!
Fired up Disk Utility and verrified the drive no issues. Rebooted to recovery console and checked all of my drives there - no issues.
Unplugged it to boot on battery like i'd been doing on day and then BOOM - same issues returned. Plugged it back in and after a few hard/reboots it's back up now.
Windows is still broken in a regular boot but will boot in safe mode. Blue lines all over the screen however.

Book a genius bar appointment and carry it instore as its probably better diagnosed in the flesh.
May be Hardware related. Not necessarily yet. The Diagnostic tool can help identify some hardware problems. Boot using the D key before the startup screen.

I haven't been able to get into the diagnostic tool yet ... at this point i have to reboot and reboot before I'm able to it to boot at all. Had to cancel my genius apointment due to a work conflict - probably be a week before I can go in.
I'll keep trying to get in - when I press the D key, I just get a blank grey screen and nothing else happens - no diag icon, or Apple logo.
WIth gfxCardStatus, I've isolated the issue to the discrete AMD gpu - crashes as soon as or with in seconds of switching it to discrete.
Reading over this thread, look exactly like my issue

Same thing here. Early 2011 Macbook Pro. After the 10.8.5 update, upon booting, the screen was shifted to one side with a big black line down the middle. I changed the resolution, the system froze. I rebooted to a white screen, the computer got very hot, fans running at full blast. I shut it off, tired to boot into safe mode, no luck. Recovery mode, no luck either. Tried to boot from my Time Machine backup, nope sorry. I keep getting to the same spot in the boot process where, I'm guessing, the graphics card switches over from using the Intel HD Graphics 3000 to the AMD Radeon HD 6750M.

I'm starting to think my whole issue was 10.8.5. I put my hardware back to stock and did a clean install of 10.8.4 and it's been perfectly fine for over a day. Hope mavericks is better than 10.8.5!
I've put back my upgraded ram and ssd and it's still going like it used to.
