Safe mode and recovery mode tend to not load specific graphic drivers or acceleration, so the clear signal there tends to reinforce the hardware trace and LCD are still fine and the visual artifacts are GPU failures.
Your research is likely right that reflowing the solder might help remedy this or it will point to a more embedded failure. Either way, kudos ...

It doesn’t necessarily need a hard drive. Have you erased it and tried installing an OS?
You’ll need an external bootable OS for this on 2011 era hardware.
Only if you can’t get that working would you need a repair. A failing disk usually doesn’t cause shutdowns without logging a prodigious amount of IO errors and any technician should be able to read the ...

There are several data recovery programs for the Mac. A few are Stellar Recovery, EASEUS, and Disk Drill. There are several others as well. A google search on "Mac data recovery ssd" will find these and more. Most of these are not cheap. Often in the $50-$60 range. Several may offer free trials though so you can test the app and maybe recover your ...

After rebooting , nothing happened. But, I found an answer! If your wifi is still working, connect a wifi enabled mouse and it works!

It still might be that the RAM isn't seated correctly, even if you pushed hard. Upgrading my older Mac, I got the exact RAM specified by Apple as being compatible.
Following the directions on the Apple support site, I felt each RAM chip click. But nothing afterwards.
Finally in a fit of frustration, I hammered all of them in with the back of the ...

I was able to get this to work using a 2013 iMac in Target Display Mode. The 2013 iMac was connected to a 2011 iMac by a Thunderbolt cable. I needed to make sure muting was not checked off and the volume was up high enough on both the 2011 and 2012 iMacs. I was able to access the System Preferences on the 2013 iMac by using Screen Sharing.
Below is a image ...

This question is one we get often. If your Mac can’t boot itself to internet recovery, you need to bring a bootable external OS to your Mac to fix it.
Your Mac could run in target mode and you download the installer from another Mac or use another Mac or person to make you a new installer.
Apple documents these steps very well. All you have to do is choose ...

It's not an issue.
You're not seeing any GPU usage because you're not using any GPU. Rendering static pages doesn't require any significant resources. Once it does render it, since it's technically not doing anything, there's no more reason for the GPU to be utilized.
Using a GPU Benchmark tool, Unigene's Heaven, I ran a process that specifically calls the ...

It may well be a software bug that Activity Monitor and other tools don't report any GPU usage. Alternatively, exactly what GPU% is measuring may be not what we think. Obviously, the GPU is doing something. You may get additional information in Activity Monitor > Window > GPU History.
My 2014 MBP with an integrated graphics unit also reports 0% GPU on ...

This happened recently to me (after an OS upgrade to 10.15.6). I also suspect that this is because somehow the OS starts to treat the network differently as before. Anyhow, what worked is just removing the network from the list of known networks and reconnecting.
