Guys / Gals

I need some advice.
All of a sudden my most stable rig is no longer stable.
One of my GPU's (RX 480)keeps dropping to 0.00 Mh/s sometimes it wont even start hashing when I start the mining software.
It was perfectly fine yesterday.
I have tried to re-install the driver to see if this was the cause.
I even selected -di 4 and ran it on its own.....when running on its own it runs perfect. But as soon as I try to run a full rig the card fails.

My PSU is a EVGA G2 1600W so that is more than enough power to run 7 cards.

I have the exact same set up on another rig and that runs fine.

I had same issue and it was caused by 'damaged' card. I ran furmark on it and it was freezing/crashing system so I replaced it.

Thanks for the input guys.

Well I'm stumped.
I decided to swap my risers around. So I chose a card from the same rig that I knew was running stable since it was only 1 card that was giving me issues.
I swapped the risers between the two cards. My thinking being if its the riser then the "good" card would then start acting up.
But now all cards are running fine?
Granted its only been 17 mins uptime. But before the "bad" card would fail after 4-5 mins .
I'm going to leave it to run for a while and see what happens but at the moment I'm thinking maybe a dodgy riser?
If it runs stable for a few more hours then I'm going to order a few more risers just in case this happens again.
