need help from claymore experts
win 10 rig with 6 nvidia mining for weeks fine, added 2 more cards and miner will not start. i have tried everything.  
loads and shows pool address then cmd window closes with no errors showing, log file has nothing past the pool address.
reinstalled driver, same.
turned off defender and firewall, same crash.
went through bois settings, nothing.
updated from 11.6 to 11.7, same.
tried only one card in main slot and in other slots, nothing.
original 6 card setup crashes.
all cards show in device manager, and afterburner.

been mining 6 months and am a pc expert but i have not seen this one and am stumped. google has nothing so I am here
 please help    
what happens when the pool address shows? from what i can find it looks at open cl and cuda support.  
gpuz show cuda on cards.
ideas?

used video driver uninstall to remove intel driver for onboard gpu and solved.
