content: Alright, I have a NVIDIA GeForce GTX 780 Ti which seems to me to be dying or dead from my quick research but I am far from an expert and new to these forums. The problem I have with it is that it creates white horizontal lines on the screen when I try to use it. Similar to the ones in this pictureI was wondering if there was some type of repair I could do on this or if you guys could diagnose it as dead or possibly salvageable.Specs:i7-4770k CPU @ GHz, 16GB RAM, NVIDIA GeForce GTX 780 Ti, Windows 7, forgot how to find PSU or any other info I'm lacking.I'm using the integrated GPU from my i7-4770k with the same stuff atm.

content: It is probably not good for gaming or even for primary display work anymore, but may still work for mining cryptocurrencies as a secondary card. If it does you can sell it for fair money if you are not mining yourself.

content: That's actually a good idea, I was wondering if people would still buy something like this. Yeah I want a card for gaming so artifacts on the screen ruins that and I'm not mining either. Not saying I'm going with that method as I'd prefer to repair it if possible but what's the best way to sell it do you think? Craigslist, ebay, something else?

content: Probably RAM failure. IMO sell it for parts.

content: In today's cryptocurrency boom people buy even totally dead GPU cards. I'd think you could test say on NiceHash and see if it works and generates not many rejected shares (as reported on your account web page) and use that to your advantage in a selling ad. I've seen WTB ads everywhere, does not matter where to sell, perhaps you could try your local Craigslist or something to save on eBay fees.I have a GeForce 460 card that died from gaming (became totally dead), I was able to bring it back to life by heating the GPU chip at 120 C for 10-15 min, it booted then fine and I re-purposed it for mining as a secondary card. It has been since running for 2 months non-stop, mining coins. Better than nothing.

content: With the price of electricity here it alone generates twice as more as it consumes in dollar equivalent at current coin prices, but chances are coin prices will continue rising and if left untouched in the blockchain for a few years it will be a few fold payout.

content: QuoteI actually totally did not expect that but at least I added more relevant information. Are artifacts on the screen usually a sign of video RAM failure?Quote from: Bud on March 07, 2018, 01:16:09 amYeah, I saw things about reflow and people using heat guns/ovens to fix the cards but it seems like a risk where I might lose my money. I might just sell it instead and buy a new one so thanks for that tip.Quote from: Bud on March 07, 2018, 02:03:37 amYeah I don't mine. I've seen far too many quotes saying it barely pays out or it's not worth it to bother.
