I've searched high and low for anything google can answer but anything with the problem I have never seems to get solved. I have one more recourse once I get home from work to try by using the Guru3D driver uninstaller but still trying to get better answers.
Upgrading Video Cards.
Going from: HIS Radeon HD 4670 1GB 128-Bit DDR3 PCI Express 2.0 x16
To: SAPPHIRE DUAL-X Radeon HD 6970 2GB 256-Bit GDDR5 PCI Express 2.0 x16
Original card worked no problem.
Install the new one and I have no video output. Fans spin up and depending on what I've done with drivers and the device manager even seems to go from full speed to slow and quiet.
While running video off the MOBO i try and install the latest ATI Catalyst drivers and such, mid install I BSOD with the atihdw76.sys being the culprit.
Now from what I've found it's a HD audio driver for the HDMI output. If I do a custom install instead of the express and leave off the audio driver it makes it through the install without a problem but still no video from the HDMI output.
I'm at a loss here. Thanks for stopping.
Rest of my build:
Windows 7 current on updates
AMD Phenom II X4 960T
BIOSTAR A880G+ MOBO
G.SKILL Ripjaws Series 8GB (2 x 4GB)
