Onboard problem

[Flameethrower]

I just upgraded a new motherboard and am using the old one i na different computer. The old motherboard was using the hd4870. Before i took it all out i went into bios and made the onboard default. i turn o nthe computer the monitor will not turn as if theres no signal at all.
I took out the cmos battery, is there anything else i can do.

I got it. I had to put in the hd4870 in pcie slot go into bios and re select onboard. For some reason it didnt save in bios but all is well.
