Bloody drivers sending me up the wall today, booted up to the much vaunted nvlddmkm.sys error. The system now boots with 1 card installed but not 2, uninstalled drivers reinstalled and when it got to the second card a bsod about a driver schedule error popped up. Even booting the machine up the strix logo on the second card flashes (as it should) then when it gets to a certain point in the booting the light turns off like the drivers refusing to recognise it and the boot basically stalls on a black screen.
Think i might just do a format as the machine has been flaky lately often taking multiple attempts to boot up for some reason.
