My lovely new BFG 680i SLI has now decided to not boot, returning error code 25 (shadow system/video bios) error. Tried changing gfx cards, swapping slots, swapping out memory and changing slots there too, and now BFG are RMAing it. Many other people come across this? I'm just a bit worried as it was booting fine, and I have a second untested board for my server that kight go the same way. I can't find much on Google about all this and have learnt to expect similar from brand new hardware but it is depressing...
