Graphic card and pc compatibility

[PatPending]

Hello,
having read some but not all questions and answers on the subject, its still not clear to me why my computer fails to boot, just heart-sinking beeps...Hp workstation xw4200 with a 410w p.supply trying to mate with a geforce gt 220...when one says "bios updating", how would that help? thanks

How many beeps do you get? 1 long beep followed by two short beeps, I'm guesing.

Your BIOS says updating when you start up the computer?

Try boot with only 1 stick of RAM, see if that help...
