I just recently updated my system and it was only my second build so... very possible something was messed up. I had the system up and running for about 3 days when it (during just regular web browsing) got the nvlddmkm.sys bsod and now I won't get a display on it. I have tried using only one monitor and one gpu. Made sure my ram was ok and I am not getting any indicator lights on my mobo. It is using the same old gpus since they weren't upgraded. I'm thinking it might be a driver issue but how do you fix that if your pc won't boot?
Edit: not sure if this helps but I did notice that none of the USB powered devices were being powered

Msi x370 sli plus (new)
