Vega 56 fail to boot . help please !!

[Alexkasu]

Hi all , this is the little story ...

I opted to upgrade my GPU bios to Vega 64 it was done successfully but I wasn't happy at all with the temperatures so I disassemble the GPU gived a good clean change thermal pads and paste and trying to get back my pc back on but unsuccessfully . Everything thing I done very carefully as is not first time when doing this . As didn't work I disassembled again I give another deep clean but the card is the same , tried to switch the bios use different cables for PSU , different PSU and nothing .
Any idea how to get the card back to life ?
Here is a video

Did you accidentally knock some of the simd components off during removing or reapplying the heatsink? It's easily done and you may not have even noticed, speaking from experience as I've done this with a 380x recently

I didn't notice to do any damages ,as I says I did everything thing very carefully ... Have you tried to fix yours ?

 

[xman2007]

No, I don't have the soldering skills or tools so it would've cost more on that occasion to fix it than the card was worth, but it's worth inspecting the pcb to make sure there's no physical damage occurred as it shouldn't just stop working from removing and installing the heatsink if done correctly

Hang on, your board posts, do you have an igp or another gpu you can use to boot into windows and uninstall the amd drivers to see if it works invert the basic Microsoft driver, if the card was dead it wouldn't post, apologies, I didn't actually watch your video when I last commented

 

[Alexkasu]

Checked very carefully and no physical damages can be seen .

Tried already , it's showing up as basic display used ddu to remove driver , unable to reinstall and when tried to reflash the bios it's says no adapter found, on gpuz show up as Vega 10 ... It's probably gone ...

Already tried with 2 cables but same, I will try heat gun method see what's going on ...

Maybe you put to much thermal paste on it and then possibly spread a bit over and some of the paste could be also electrically conductive.....check again and wipe it good first......

 

[Alexkasu]

Already re-clean after first fail , I will wait another 2 day see if anyone's came with a idea

Try to clear CMOS by removing the battery off the board..

First, drain any power by disconnecting the power cord, then keep pressing the power button for a while.

Locate the battery on the board then remove it, wait a couple of minutes

Now reverse the whole process, put the battery back, connect the power cord, boot up and hope for the best.
