I have a new motherboard, CPU, video card, RAM and display.
MD Phenom II X4 955
Asus EAH5770 CuCore 1GB DDR5
When I boot up, the display detects no signal from the video card. Everything seems in order: CPU fan running, no warning lights, the graphics card power supply is connected.
The GPU fan is running, but at what I assume to be maximum speed because it's very
loud. I've tried both DVI and VGA connections.
The display is OK when plugged into my MacBook Air via DVI.
There is no OS installed yet.
Does anyone know whether I have a compatibility problem with this mobo/graphics card combination?
Any suggestions about what I should be checking?
Anything I may have overlooked?
I don't have another video card to double-check - the old one is 500km away on a box I built for my daughter - and running beautifully. :(
