I think we've all done the press randomly and hope.
It's not very effective.
Nor is the fry it at 250c for 10 mins.
You're going to need tools, time, and patience if you really want to fix it.
Start with a multimeter and some datasheets.
Do the transistors have a normal looking output voltage? (Eg ~3.3, 2.5, 1.8v)
Do the chips get a normal looking voltage on their enable pin?
Edit, just looked at the pic.
It's practically certainly memory related.
Nvidia has mats/mods that can run a memtest to isolate which chip.
There are similar tools for amd.
Once you isolate the chip, look for bad caps and resistors around it. Look for bad traces.
If nothing looks bad, it is either the memory chip (not too hard to replace), or the core (much harder to reball)GPU stabbing looks something very hard to grasp. And it doesn't look like there are very good guides out there. And I probably need to start with something more basic. I haven't studied electronics at all in school. What I can do however, is replace stuff that looks broken, at random, and hope for the best. I actually got a WEP 858D Hot Air just last week. I was told it's great for hobbists. Thoughts? I can still return it. Also got silicone mat, wicks, leaded solder 63/37 of 3 sizes. I need flux that doesn't cost a fortune (surprisingly hard to find a good deal. top brands are 50$ for tiny syringes which is crazy to me) and a microscope. As with flux, I can't seem to find a good microscope that doesn't cost a fortune.
Run the memtest software first(find it first).
Isolate the memory chip.
