Hello everyone
So I have this mining rig with multiple GPUs from nvidia :
2x 1660 TI
2x rtx 2060

So far, with 4 gpus everything worked perfectly
A few days ago I bought the fifth gpu, a rtx 3070
When I plugged it into rizer, powered it with the power source, the computer won't start anymore
At first I thought it could be something with the new GPU, but then I disconnected another GPU and left only 4 of them
It seems that It works with any 4 GPUs but when I connect the 5th GPU motherboard simply won't start anymore and I get this 2 screens:
First one completely blank with only one bar "_" blinking in left upper corner of screen

So I get this screen at first and then if I wait a few minutes I get a second one saying:

Reboot and Select proper boot device
Or insert boot media in selected boot device and press a key




If I unplug any of the GPUs and leave only 4 again, it will work normally.

I have also tried following solutions:
-updated bios to latest version
-activated 4g decoding
-primary display to CPU Graphics
-DMI MAX LINK SPEED changed to GEN1
-PCIEX16_1 link speed changed to gen1
-PCIE speed changed to gen1
-M2_1 configuration changed to PCIE



I tried all these settings from bios and nothing worked

Can anyone please help me?
I am out of options

I tried every possible option from bios...nothing seems to work
I heard something about reinstalling windows and making a uefi partition
Could this be it?
