I know that much, but you know those shows where the doctor tries everything to save this one little kid that has cancer from dying and despite everyone telling him he should give up he tries again and succeeds? I could use one of those moments right now... for 30€ Graphics card... that's not even mine... maybe i exaggerated but you get the point.

Hey there dear LTT Forum User, As you already read, I've got a problem. Long Story: I bought a used HD 6850 and it worked perfectly fine, I opened it up cleaned it till it shined and put that thing back together as I always do with used Hardware. Now, I gave this card to a friend as a gift since I made sure it was running fine and tested thoroughly etc. She got the card put it in and played the For Honor Beta easily and some day she started some random game called Ship-something i dont remember. She played for 10 seconds when suddenly her PC instantly shut off and it started smelling like burnt electronics, (she told me that and i thought the PSU must have had too much since it is a 425 W PSU and this game was very poorly coded.). Not knowing what to do, she fired the PC up again but it refused to boot and only after 30 minutes of waiting she managed to turn it on again. After that green lines appeared and drivers weren't working anymore same with MSI Afterburner. Note: It was still detected by Windows. A few hours later she gave the card back to me and i was kinda confused from what she just told me but I said: There is surely a way to fix this... Still found no solution... BUT here are some key infos: The card is still running and putting out a signal. The card has no visible damage to it. The card will refuse to boot when proper drivers are installed. The card won't put out the correct resolution due to missing drivers. What I wanted to do: Use a program e.g. AMD Overdrive and reduce clock speeds for both core and memory to get rid of those ugly artifacts, aswell as voltage to take a little stress off of her PSU. What I managed to do: Nothing, since no program i know is able to do that without drivers and evertime I install a driver the PC won't boot. I'm running out of ideas (i still got some though) but I decided to get some help before I waste many more hours on this. TL;DR: HD 6850 crashed, Artifacts appeared, It isn't detected through any 3rd party app anymore, Installing drivers makes the PC not boot properly and only boots in safe mode (I'm writing this from safe boot with internet connection... what a time to be alive ) HALP Thanks in advance!
