Are you running the cards at stock?

First I'd reinstall your drivers, try the latest non-beta release.

does the whole system lock up? 760watt is kinda of pushing the limit especially if ur overclocking anything..

Run driver sweeper first, then do a clean install.

Should be alright tbh.

So i small update, after doing what you said. Then i can see one of my cards is not working full out. Getting small black arenas on the screen, so time to test the cards full out in a build to a mate.
