Dell Precision 3260 with  240W power adapter,  I upgrade graphics cad from NVIDIA T600 to NVIDIA A2000. OS Version Win11 2022 H2, graphic driver R525 U1 (526.67)

It Works well before upgrading BIOS from 1.6.0 to 1.73 .After upgrading,  graph card completely not working, Window 

login screen crashes directly and reboot automatically. Login to the system using  integrated graphics card，as long as the application uses the A2000 graph card, OS will restart with a blue screen

 

 

Downgrade to version 1.6.0，problem solved， graphics card works again
