7970s not posting/giving output

post #1 of 2
Thread Starter 
Alright, so I finished my watercooling loop the other day to find out that nothing would turn on what so ever, since then I discovered it was because i had tightened my GPU backplates to tightly and they were shorting out the cards, i have loosened them and now my system turns on, kinda. Now my problem is that neither one of my 7970s are giving an output. The red VgA LED on my X79 sabertooth will light up on boot telling me that there is an error and it wont turn off i have inserted a 7770 along with my 2x7970s to see if the LED would turn of and funnily enough it did and i was able to receive a signal on my monitor. Once in windows i went in to MSI after burner to see if it recognized my 7970s but i was not in luck.
Any suggestions to my problem are much appreciated.

Welcome to OCN smile.gif

Remove them both from the mobo, unplugg power connectors & test with just one 7970. Then test with the other (one at a time). Try several slots.
Try flipping the Bios switch on each card. I doubt you fried both cards.

Here's how to put your rig in your sig:
