Added 2 gpu, now motherboard having issues

jwilliamson47 · 20 Nov 2014 at 19:32

I'm using a z87xoc motherboard and it was all working, until today when i added a 2nd gtx 970.

The board starts with an error code 19 then instantly moves to 15, and just endless reboots without posting an image on the screen.

Any ideas?

Thanks.

I'm not using the soundcard at the moment, I'll do a bios update, if i can to see if that helps.

I've noticed it comes on for like a second cuts out then boots again, also, my keyboard and mouse are not working anymore.

can't even get into the bios, i've used the switches and disabled each gpu, and both and that did nothing so can't be a gpu issue.

Trying the RAM now

Ok, I really don't understand this at all.

Booted with only 1 stick in both slots 1 and 3, works fine.. used the other ram in slot 3 works perfect, fails in slot 1, then move to 3 and fails again.

Reboot, try in slot 3 then posts

Trying both sticks fails too.

slots 1 and 3 for better airflow.

Bizarrely, using 1 stick for a few hours and leaving the machine off at night, fixed it when i added the 2nd stick on the first boot.

I have a soundblaster Z, but there isn't a lot of room between the gpu and next pci-e slot.
