MacBook Pro 17” 2012 blue screen issue

[Krupal]

About a year ago i removed a DVD drive and installed an SSD and created a Fusion drive.
Now about a week ago i am facing an blue screen issue, startup issue, random restart at starting screen, only white screen, if some how i can get in to log in display get split up from middle. I changed a RAM, I cleaned motherboard with PCB cleaner , applied new thermal pest but no resolution.so I thought it was software related issue so I formatted from recovery mode now i can't even install a new OS or restore backup from time capsule.
Any ideas ?

P.S. i also diagnosed hardware by pressing option + D and its passed all test

Can you boot into single user mode?

Presumably, now there is no system on the Fusion drive and installation somehow fails.
I would try to boot using external drive/USB stick and see, if I can run form there. You can connect some external USB enclosure with any drive (SSDs are cheap now and Hard drives are even cheaper), create USB-stick installer from Apple Store installer (instructions on the web, you need working mac for that). You can install from that USB stick onto the USB external drive and if that works, most of the computer is OK. The only thing left would be the Fusion drive.
I actually run for two weeks my MBP from external USB drive and it was not too bad. Slower - yes, but usable.
SSDs are cheap today, I would break the Fusion drive, got 1TB (~$120) cheap SSD and run without Fusion drive. If it works, it will be faster and more reliable/robust that Fusion drive.

Hi, I think they stopped making the 17" in 2011, so you'll have a 2011 model. The likely problem here is a graphics card failure.

There's a workaround here (but you lose dedicated and external graphics): https://forums.macrumors.com/thread...ntel-integrated-gpu-efi-variable-fix.2037591/
