Ups lite hjälp med sli!

Skrev inlägget på engelska så klistrar in bara hoppas de går bra

So i bought a new gtx 980 to my rig to do sli with my other gtx 980 on win 10 (trouble )
Turned off system and installed the new gpu.
Booted up and win 10 updated and found sli avalible so I enable it and startet Valley Benchmark test…as soon as it started to hit some load the pc restarted. So I booted up and started valley again…same thing. And now I saw aswell that the drivers for the cards was gone, crap shit it my psu then right?

I bough new psu and installed, win works fine so I tri to install the video drivers but I can only get the new card installed, the old one is getting “error code 43 or code 31” so now I try a hell of a lot to fix it, drive wiper from guru(DDU) changing slots etc etc and im am right now at this..

The new one works fine wherever I put it, the old one on the otherhand (that I know works) i cant get any pic on even in slot 1 or 2 EVEN with the mobo graphic plugged in it kinda “overrides” mobo and gives me black screen…everything runs in background just no pic.
And just found out my second hhd is not spinning as well, tried a old hdd and that one spinns with same cabels.? = O

Inte kan eds sabbat både ena grafik kortet och min HDD??

And ideas what I could do, it seen really weird if the card is broken, I played it the night before for a couple hours and it worked fine!
