I've bought Z4 G4 to replace my Z420 that's blue screening. I've got a Nvidia GeForce GT640 card spare and
had hoped to use it in the new workstation. Switch it on and I get 3 white and 3 red lights with beeps. I took it out and tried
to boot with no card, does the same thing. Is it the computer or the card?

the GT640 card is not fully UEFI compatible, you should try/use a newer card that does support UEFI such as the nvidia 1030-1060 cards or other 10xx /20xx/30xx models
