MacBook Pro 15" Early 2011 stuck on white screen after apple logo
My MacBook boots up with the Apple logo just fine, but afterwards it just stays stuck on a white screen.
I've tried booting into recovery as well but instead of a white screen, I get a blue screen, and it just stays there.
I'm certain it's not a hard drive issue because I used multiple hard drives and got the same results and the hard drives I used work fine on other computers.
I've also tried booting into safe mode and resetting the VRAM and PRAM. I can't reset the SMC because there is no battery in the machine at the moment.
Other than the hard drives that I am testing, the only thing inside the computer is the RAM and logic board.
Is this a GPU issue? Logic Board? How would I be able to fix this?
