Z4 G4 using an Nvidia GeForce GT640

[plans2build]

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

Many thanks for the reply. My only concern is that the machine doesn't boot even without a card.

that is normal, the system detects no video and gives a error, you should try reading the user manual which covers things like this

Thank you but it was technical support that told me to remove the card and turn it back on. I then reported back the result. I have ordered a new graphics card.

Thank you for your assistance. I bought a new card and the machine is working perfectly.
