Hey there,
I've got a MacBook Pro 15" from Beginning 2011.
Since a few weeks it freezes on startup (white screen with apple logo and progress bar on 60%)
I've tried PRAM/NVRAM, SMC, Apple hardware check(no failures), and I switched the RAM-modules vice verca, even a new hard disk cable.
Nothing helped.

Then I installed a small SSD for testing and installed HighSierra. After that everything seemed to work fine, I restartet about 30 times, without problems.
So I thought it is the hard disk.
I bought a new 500GB SSD and installed HighSierra again. All seemed fine so far.

Yesterday I installed the newest updates.
After that my MBP froze and showed me a completely red picture when I wanted to start the photos-app.

Now the MBP is not starting again. After the white screen with apple logo and progress bar(60%) the picture turns black and all fans are running on 100%.

Does anybody have any ideas?:(
 
The GPU has failed and there is no way to fix it without replacing the GPU chip.

Unfortunately, the extended warranty for this issue has expired.

I had a late 2011 15" i7 that exhibited similar symptoms.

Now I got the MBP starting again to the Desktop.
It restarts reliable, that as soon as I want to open 'Photos', 'Photo Booth', or 'Grapher', it freezes and shows a red screen. Sometimes the windows comes back, with everything red around.
So I can kick it in the trash or will it might help to downgrade to Siera?
 
I agree with @Audit13 , it seems you GPU is failing but there is a workaround. You can disable the dGPU and use only the integrated one.

I did it to mine using this guide: https://forums.macrumors.com/thread...-on-a-2011-macbook-pro-grub-solution.2087527/

Still works fine to this date but it can't run most GPU demanding tasks and you have to re-disable the GPU for every major upgrade (not a big issue for you since you're already at one of the latest big upgrade available for that model.)

Thank you guys, you are right obviously. I played with gfxCardStatus, and as soon as it uses the dedicated gpu it crashes.
What are those "sleep issues" mentioned in your link?
As I need to run Windows as well I think there is no solution under windows, isn't it?

I used to have some issues bringing it back from sleep when I used another method but with the one link I have no issue at all.

Windows should run too once the fix is applied, it's done before any OS is loaded.

Im done with MBP. I got an iMAC. No more fan issues, no heat, no noise. Larger screen. Better sound system. Less money. Simply fantastic.
