It sounds like the cards are not functioning properly, like I said before. If you tried plugging them into multiple systems that are able to run identical cards in the same slots, but these cards are unable to do anything then that would indicate that the cards are in need of repair. You can try running them on a new OS, but since you are in windows 10 are you able to see the GPUs under device manager? Since they are receiving power, and the fans are turning it is possible that the drivers are just not installed properly, but device manager should help us get a clearer picture of your situation.

Even turning off the PSU is not enough to prevent shocking the cards, even shocks that you are unable to physically feel, because of your threshold for "pain", are well above the amount necessary to kill computer components. Anti-Static bands, discharging your static electricity and making sure you have clean hands when you get inside your computer are a must. Were these cards working properly just a few days ago or have they always been giving you a tough time? What happened between when they were working and when they no longer were functioning as intended?

In device manager I see 3 of the 5 GPUs. I'm taking notes about discharging the static electricity, thanks for all the tips

. These cards were detected for couple of hours first but when I added more GPUs on the motherboard, some GPUs went off temporarily they came back but those 2 never came back even if their lights are all on and on the risers too (this tells me that the power are OK on it, so .. cannot be or low chances that they are defect right? I am thinking of migrating to a mining Linux OS like SMOS or HiveOS since Linux is well known to handle the ressources way better then Windows. I will also try to plug 1 of the buggy GPUs directly in the PCI-e x16 slot with all others GPU unplugged as soon as I get back home.

Thanks for all your suggestions and if you think about anything else please don't hesitate to hit me back here ! Grin
