GIGABYTE GA-Z68XP-UD3 Video Issue - No Picture from discrete Graphics Card

I posted this at Anandtech - thought I would try here too in case somone has a solution. I finally have my computer together and running; And now running cool with a Coolermaster Hyper 212 Plus cooler installed (dropped my temps from 80-90 degrress C under Prime 95 full load to 45 degrees, but I digress).

Here is my setup:
GABYTE GA-Z68XP-UD3 MB
Intel 2500k CPU
1 TB WD SATA III Hard Drive
Patriot Gamer 2 Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM (PC3 10666) Desktop Memory
OCZ ModXStream Pro 500W Modular Power Supply (OCZ500MXSP)
Random DVD-RW-DL
Running 5 Case Fans (3 on the case and 2 on the CPU Cooler)
HIS Raedon HD 5770 Video Card

As noted above, I finally got it running cool last night and went to add my video card to the system. I had been just using the onboard GPU through the HDMI connection until I could get the right CPU Cooler and get temps I thought were okay even without overclocking. I turned it off, added the card, connected the DVI connection to it (HDMI unpluged) and turned it on and - NOTHING on the video. Computer beeps, loads windows (you hear it load), is apparently running, but no video. Video Card has power as the fan was turning. It works in my old system. I turned it off, moved back to the built in HDMI connection - and now no video from it either. Shut down, took out the 5770 video card, turned it on and had picture. I went into BIOS and found a setting for selecting first GPU to boot and selected PCIe 16x. Put card back in. Again no picture. But then, to get back to any video with the built in GPU through the HDMI I had to reset the MB....I have tried to make sure the card is well sseated, doing this now 4-5 times with no picture frm card. Have tried card in the x8 PCIe Slot too.

What am I doing wrong or missing on this board ?

I am not sure if it is a problem with the motherboard, or a video conflict, or what, but I got it working last night by making two changes in the BIOS - Under the Advanced Bios Features Tab there are two settings titled "Init Display First" and "Onboard VGA". I set the Init Display First to PCIE x16" and set the Onboard VGA to "Enable if not Ext PEG". I don't think you should have to change these settigns to make the external card work, but it is now working and of course onboard VGA is disabled. This is from the motherboard manual on these two settings:


Init Display First
Specifies the first initiation of the monitor display from the installed PCI graphics card or the PCI Express graphics card or the onboard graphics.
PCI Sets the PCI graphics card as the first display. (Default)
Onboard Sets the onboard graphics as the first display.
PCIE x16 Sets the PCI Express graphics card on the PCIEX16 slot as the first display.
PCIE x8 Sets the PCI Express graphics card on the PCIEX8 slot as the first display.
Onboard VGA
Enables or disables the onboard graphics function.
Auto
Always activates the onboard graphics, whether or not a PCI Express graphics card is installed.
If you wish to set up a dual-display configuration, set this item to Always Enable. (Default)
Enable If No Ext PEG
Activates the onboard graphics only when no PCI Express graphics card is installed.
Always Enable
Always activates the onboard graphics, whether or not a PCI Express graphics card is installed. If you
wish to set up a dual-display configuration, set this item to Always Enable.

It would still be a very wise choice to replace the PSU with a good quality 650W unit.
SeaSonic-XFX-Corsair (not the CX or GS Series) are top quality.
