I have two MSI GTX 570's. Both are not flashed or overclocked. my system is not overclocked as well and am running them a Asus Maximus IV with the newest bios out and newest drivers. PSU is a Corsair 1050 Watt. I just installed fresh windows and got a new sli bridge. no luck. My only temporary solution is when i go into device manager and disable and then re enable one vga adapter for Nvidia control panel to let me enable SLI. I tried reseating the cards and i find that only when i reseat them that they get detected. But once i restart Nvidia control panel says there is not device linked to the software. I single stress tested them both and work fine. I cant figure out if its a software or motherboard related issue or what.
Tried reseating both cards
Tried switching slots/ cards around
Tried a new SLI bridge
Tried install of new windows
Newest Bios is on Motherboard
nothing is overclocked
tried Previous versions of Nvidia drivers with Driver sweeper
