I have 6 Asus RX 580 with Z270-P motherboard, that I bought last week ! they were working fine.
But the rig stopped working , now i found whenever i connect specific GPU the windows won't boot . but when i connect the other 5 it works normally .
I tried uninstalling the drivers and reset the GPU Bios to the original , but still didn't work . the computer freezes on startup .
I have tried to change the riser in case it's causing the problem , but I still the same issue .
What can I do ? if I return it to the supplier will the warranty still works ? or I voided the warranty when i modded the BIOS ?
