So I bought a broken graphics card, in the hopes of fixing it, here: https://www.ebay.com/itm/373724033649?ViewItem=&item=373724033649&nma=true&si=2U3AvStmceGGbbEwqwoDTTv%2Bce8%3D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557

it works, but has some problems, mostly just going to a black screen when in boots, or randomly going to a grey screen during use

so far i've:
-reapplied thermal paste
-performed a fresh install of windows
-used safe mode to get the card running to install the most recent drivers
-ran a benchmark for ten minutes to make sure that it works
-restarted my computer to make sure the device configuration worked

after all this, while it does work (i tested it on with a 10 minute benchmark, as well as a game of CSGO), it still crashes after use

the computer is running on a gigabyte ultra durable motherboard with a ryzen 3 3200,16 gb of ddr4 ram at 3200Mhz and an EVGA 650 watt power supply

As a guy who has been buying 3 dead gpus and has fix 2 dead gpus because gpu prices has been too expensive, i have some suggestions.
When you say gray screen or black screen then i think the problem would be the VRM of the graphics card, mostly the problem of the vrm is the mosfets because mosfets overheats very easily thats why it becomes faulty easily.
You should try and undervolt or underclock your gpu so that your gpu wont use too much power, since the VRM of your gpu is faulty you dont want it to use too much power or else it will crash.
Another solution is using the baking method which is a method that you cook your gpu, now you may think im crazy but it has worked for multiple people including me and this method has been around for years. So how it works is very interesting. Often gpus fail because of high temperatures due to loosening solder joint, and to reconnect that solder joint youll need something that will make it hot to melt that solder for that solder joint to connect it again and an oven or a heat gun would be the solution to make it hot.

Anyway lesson learn is just dont do this you might lose money, be patient for gpu prices to go down. I heard that intel is going to release their gpu line up in 2022 so thats some good news.

Heres some links that would help you out:

I would first clean the gold contacts with a alcohol wipe. Then try using older graphic drivers. You can try using msi afterburner and turn down the settings a little bit a time to see if you can find a stable setting and still get enough performance out of it.

i believe the problem was just a poor connection to the pcie of the motherboard, but for future reference, could the VRM overheating be fixed by applying fresh thermal pads? i plan on continuing this poor idea, as i've had some luck with it, and any help with potential fixes in the future would be appreciated
