- Friend's R9 390 Sapphire stopped working after he dropped his PC by kicking it accidentally, had black screen issues before that too and now GPU doesn't even start when he powers on his PC
- I took a look at it and found out that a Resistor was fried and that is apparently a common issue with 390's. I tried putting it in my PC too and it wouldn't work.
- I replaced the Resistor, my soldering skills are bad but I thought the result was sufficient
- I took out my own 5700XT, which is working fine and put in the 390 to test it (Motherboard X570 Aorus Elite)
- Doesn't work, same issue as before
- I remove the broken 390 and put my 5700XT back in
- Now 5700XT doesn't work - no LED, no signal, fans still
- I put the 5700XT in the other PCIE slot (I have 1x PCIEx16 and 1x PCIEx4) and it works
- I have not put the 390 in the 2nd PCIE slot for obvious reasons.
Any help is greatly appreciated
