So basically, my motherboard has just Killed 4GPUS!
I think, there is a problem with the PCIE port on the motherboard and it keeps killing GPUs.
I've tested everything and even added some cheap GPU and it died as well, so its 100% mobos fault...
GPUs are out of warranty, so what do you guys think, are GPUs done forever? How great the damage could be on GPU from motherboard? no smoke or anything like that was noticable....When I turn on the PC, GPU's fans and Led lights start but then it stops and pc can't detect it...
Ok, so, I have been looking down your posts, I see you are using 2x PSU on that rig? Correct?
Is it possible that you had problem with groundings on your rig, so you get reverse electricity current flow.
People had this type of burned machines a lot of times.
