Hey everyone, i just bought a new gtx 480 and tried to go about installing it myself. I uninstalled my old drivers and installed the newest ones for the 480 from the nvidia website. However when i put the 480 in my computer and try booting, my mobo just emits three consecutive beeps repeatedly and doesn't start up. My computer is quite old, I have a 630i motherboard and ddr2, is there a system requirement i'm missing? im not quite sure what's wrong.
