A new Pci x16 HD 3850 256mb video card came in today. Plugged the monitor cable in the card, turned the power on and only the video cards fan runs pretty loud no signal so I plugged the monitor cable in the motherboards on board graphics and got display. Why is that?

Also my bios version is 786C1 v02.15
Motherboards model is 0968h according to CPU-ID

You won't get any video from the new card until you install the drivers. You may have to go into the bios and disable the onboard video first. You should have gotten the driver disk with the card,

Before install v-card un-install oboard video driver then go to bios & return shared memory, disable onboard video, set initial display to pci-e then save changes, shutdown the system and install v-card. make sure latest driver for v-card is installed.
post your system specs including psu specs (+3.3v,+5v,+12v).

You need the driver for Windows, but not the initial bios displays.

The three most important things in computing:
1. Backups, 2. Backups and 3. Backups.

Removed the card and installed drivers using the disk plugged the card back in and still no display out of it. Older pci x16 cards work though without a disk

@kuwese

No options in the bios to do neither of those

My power supply is a diablotek 500w psu
The box that came with it says
Efficiency 78% at typical load
Ac input voltage 115/230V
Ac input frequency 60/50Hz
Ac input current 5A (RMS) for 230 VAC input

Ac input 115V/230V - 60/50Hz
Dc Output +3.3V +5V +12V -12V +5VSB
Max. Combined Wattage 28A 30A 24A 0.5A 2A
500W

also it came with an 6 pin adapter of some sort for the hd 3850 that fits so i plug it in with the card

@aegis1

David, you do not have a driver problem. A driver is not needed to get the first screens when you power up. A driver is only needed for Windows.
You need to determine how to have your bios switch from the built in adapter to the 3850 for your PC. I don't know how to do that.
I guess it 'might' be that your power supply cannot supply the current needed. Maybe someone else will know about that.
