i5-2500K GIGABYTE GA-Z68XP-UD3 Motherboard G.SKILL Ripjaws X Series 8GB (2 x 4GB) XIGMATEK Gaia SD1283 CPU cooler SAPPHIRE 100315L Radeon HD 6850 Intel 320 Series 80 GB SDD (boot drive) SAMSUNG Spinpoint F3 HD103SJ 1TB HD Antec High Current Gamer Series 750W PS Antec Nine Hundred Black Case Windows 7 Home Premium
Initially I had post beep, but no display. I tried removing the 6850 and use the built-in graphics and was able to get video display after clearing CMOS. Now Windows is loaded and everything is up and running using the integrated graphics, but I can't get it to display with the 6850 card installed. I can hear windows loading, but no display. If I try to go back to the integrated video output, it doesn't work until I clear CMOS again.
The 6850 has power (at least the fan is running). GIGABYTE motherboard is suppose to be enabled with Virtu (allowing dynamic switching between the built-in graphics and the discrete graphics cards) but I went ahead and tried configuring bios to disable the internal graphics when a discrete graphics card was installed, but that didn't seem to make any difference.

Did you connect the PCIe power connector to the HD6850? If so, make sure it is firmly connected and try again.
Yup. Power connector on and firmly seated. Even switched it out with another power connector off the PS. No change.
