So I have a bit time on my hands and I was thinking on trying to repair my hd7850 , it just died one thay and its not posting . I know how to do that but will doing that relaese some fumes into oven ? Also what temps should I use and for how long .
Yes, it will release toxic fumes into your oven and from what I've seen you shouldn't use that over for food after doing this. Linus Tech Tips on youtube did this before and does an entire how to. But this is typically a temp fix and not a permanent fix for GPUs.
Hit up a used store and find an old toaster oven is my suggestion. (Also great for large interference fit bearings and hobby SMT soldering jobs)
The very occasional broken off component or trace repair is possible as well, but these days you need a pretty steady hand. That stuff is getting tiny.
Can we all slow down for a moment please? OP hasn't been able to provide information proving that the problem is the graphics card. How do we know it's not the power supply or motherboard?
Problem is in GPU , I tested 7850 in 5 other PCs , and it didnt post , but when I put other GPUs in PCs they post . So yea Im preety shure its dead
That proves it's the graphics card, not necessarily the GPU though. Could be a capacitor or FET on the card.
I was just making sure. You'll be surprised how many users create these sorts of threads and are sure what component caused the issue even though they haven't done any testing yet. Many times, it turns out to be something else than what they thought. Motherboards and power supplies seem to be most common.
