Issue: Display Adapters under Device Manager does not detect a new MSI R7950 graphics/display adapter.
Most recent PC upgrades have been installed.

I upgraded to the most recent 1.H0 BIOS. PCI-E selected in CMOS.
System attributes include:
MSI 790X-GD70 main board with 1.H0 most recent BIOS
Chipset driver version, most recent: 8.881.0.0
VGA driver, ATI, most recent: 3.0.745.0
AMD 965 AM3 Black Edition processor
RAM: 20Ghz
HDD: 2Tb

Might someone know what else I need to do to get Device Manager to recognize the R7950?
Or must I upgrade to a new main board?

The board should be compatible! Did you connect power from the PSU to the card? If so list your full specs and include PSU.

That's great news about board compatibility.
I checked the voltage inputs to the six-pin connector and the four-pin with two tails. Both tails are connected. I detected 12 and 5VDC readings. Both fans run on the R7950. The R7950 is indeed locked in to the PCI-E connector. Further, a manual "Scan for hardware changes" will not discover the R7950.

PSU is 550 Watts.

4 pin two tails? Sounds like the CPU connector 4+4! Should be 6+2 for a 8 pin PCIe!

Sorry. That's a six and an eight-pin connector that plug into top of card. The six-pin Molex has two tails, each with a flat four-pin Molex. Both were plugged in. Voltages of 11.98 VDC and 4.95 VDC were measured at the connectors plugged into the card. Both cooling fans rotate.
