Help with broken 980Ti, please

[strumpusplunket]

An updated request for help here:

I got the card out again last week and tried to put it in my kid's PC as he has a 2200G with iGPU. Except - of course - it won't fit in his micro-ATX case!

I guess the only option if I want to try flashing it with a lower-clocked BIOS is to stick it as a secondary card in my PC. But I've never done this before and I have a few questions:

• How do I make sure the PC boots up using my 1080Ti as the primary display card? Is there some BIOS option for this?
• I'm assuming that then it won't matter if the 980Ti isn't working properly as it won't need to drive a display? Will the system just not use it unless I tell it to?
• When I come to use nvflash to flash the 980Ti's BIOS, how can I make sure I don't flash my 1080Ti by mistake? Is this easy to do?

Plug the monitor into it, and plug nothing into the 980ti

Plug the monitor into it, and plug nothing into the 980ti

Oh! Simple as that?

Is it straightforward to read and flash the BIOS of the correct card with GPU-Z and nvflash? I have this (possibly irrational) fear of bricking my 1080Ti by flashing it by mistake!

Pull the 1080ti out of the machine and use the onboard graphics (plug HDMI into the motherboard HDMI slot).

I don't have onboard graphics on my pc. My son's does, but that's the one I can't fit the card in.
