MacBook Pro Early 2011: Startup issues, Color Glitching, Freezing, Fans working Fast, Heating Up, and Apple Hardware Test not completing.
Hello Everyone! Hope You All are Safe and Well.
I have an Early 2011 MacBook Pro. Next Month will complete 11 Years of using the laptop. In 2017, I upgraded the RAM to the full capacity of 16 GB (2 x 8 GB), as well as put in an SSD. Since January, the laptop has been having major issues, that several Time Machine restores have not fixed. I have to reboot the laptop several Times before I can get to the login screen. There are color glitches, the laptop keeps freezing, Extreme Heating, and the Fans start going really fast.
After doing a Time Machine restore, the issues temporarily go away, but come back. When I try going into the menu to do a Time Machine Restore, the colors sometime mess up there. Sometimes it takes several attempts to get into that menu, and sometimes the screen shuts off, and I cannot turn it back on, so the Time Machine restore does not complete. The Apple Hardware Test keeps failing (long and short versions), since the computer freezes just before completion. The colors glitch out there as well.
The SSD has enough space, reads and writes well, so it does not seem to be the issue. I did the REMBER Test, and it did not show any errors. It seems the issue May either be a GPU or other hardware issue.
The laptop is currently on OS Sierra (issues started on OS El Capitan, that is why I upgraded the OS). I’ve spent many Hours on the phone with Apple, and have tried many of the commands. Is there any additional test if the Apple Hardware Test does not complete? Could the RAM be causing the issues? I could get a replacement, due to the warranty. Would replacing the RAM fix it? These issues just started in January. I’m not sure why AHT does not complete. When it’s working, the colors are fine, but after the color glitch starts, the cursor even mutually stops moving. Then I have to reboot. When the laptop has issues, I try to reboot, and I often get stuck on a White Screen, or a pink status bar, and I am unable to get to the login screen, so I have to try several Times.
I would really appreciate any advice.
Thank You.
