I used to run 8cards without a problem, but one day it stopped working, somehow the 1st card throws out an error of 43 somehow and I tried installing and uninstalling it, and strange part is sometimes the cpu will detect as 8cards, and when I run miner it hung and restart it detects as 7 and the miner will run just fine, and whenever it detects 8 it always hung when miner runs?

I tried moving to another pc but its still showing the same 43 error, does that means my card is screwed?
