If can describe to us about powering schema with dual PSU. it will help us to analyze what caused it. otherwise, you could try to run all of your cards and disable one by one through claymore, it will which cards be causing your system crash.

1 PSU powering your mobo and two cards also another part such as SSD/HDD. and the other PSU use for powering the other 3 cards use the second PSU for powering Riser but make sure the second PSU produce the right voltage if you're using jumper start give them dummy load on 5V.
