Fried Graphics Card... What else would be damaged?

[QuantumBedrock]

so I run double sli in my set up and I fried one of my graphics card and tv by trying to plug my tv into it to play a game off of it rather than my monitor like I've done before. After it fried I took it out and tried putting the second one in that gpu slot but when I start it up it starts up and has a different Microsoft loading screen then normal... then goes black and the Windows start up noise comes on and it says no dvi source... could I have fried the mother board too? Like the PCi slot? before I took the fried one out I tried turning the pc back on and the VGA light came on so I knew the graphics card was fucked. But the other gpu seems to be fine. Unless both of the graphics cards are fried and the motherboard is fine... I don't know. please help:/

What's your hardware? If the CPU or mobo has an onboard GPU can try connecting through the mobo to monitor/tv. If that works, shut down, remove the Discrete GPU card boot, and remove all the cards drivers, then try reinstalling the card (good (?) one) and see if you can boot through it

I had a similar issue with a GTX 570 way back when in sli and i had to do as tradesman said (though i had no igpu i had to use the other card from sli by itself)...for what ever reason it temporarily friend a DVI connection and only removing it, running DDU (display driver uninstaller) with the other card only....then after unloading the old driver i put the new card in and reinstalled the drivers. point is his advice is solid as usual!
