this gpu is likely overheating .. i have too with the same symptom
maybe need reflow or reballing .. or maybe it just dead

Are you the original owner of this card and have you had it working before you got it? If yes, then try new thermal compound. If problem persists, it's probably time to reflow or reball the GPU (at which point, it may not be worth it if you don't have the tools and equipment... so just sell on eBay or locally as "for parts or repair").

Try the new thermal compound first. If that doesn't work, then do the reflow/reball.

However, I should mention that the 858D+ probably would make this very difficult to do, since it can't really provide enough heat flow to remove the chip. At the very least, you will need some kind of bottom heater (electric stove top works with a bit setting-up). And even then, there's a high chance you will damage or pop-corn the chip with the top heat from the 858D+. But if nothing else, give it a try and let us know how it all goes. The card is alreade not working, so not much to loose. Though if you do want to make some money off of it, sell it on eBay "for parts or repair". Should get a reasonable pocket change for it.
