I thought I'd upgrade my 3-way GTX670's and got a couple of the new GTX980's, however after doing so, my computer won't post. I have the Asus P9X79E-WS motherboard and it keeps showing me the Q-code 62, meaning "Installation of PCH Runtime Services" and showing a blank screen (no signal detected).
The idea was to benchmark one card, then do it again in SLi to see how the card scale, so I started with only one card in the machine, on a dual-link DVI.
After a while of trying different things, checking things were plugged in properly, booting with no USB devices plugged in, clearing the CMOS etc. etc. I swapped the card with the other one, both cards are brand new; same result!
After putting a single GTX670 back into the machine, it booted like it would when you clear the CMOS, after going into the UEFI and doing some basic setup, like boot priorities etc.. I booted into Windows perfectly, and here I am typing on this forum. Surely both cards can't be duds?
Anyone have any ideas??
Thanks!
