I just tried to install a FX8350 cpu into my sabretooth 990FX motherboard and when I tried to start up, my monitor was not receiving a signal. My motherboard does not have any video out ports so it runs through my GPU (Radeon HD6950), I tried both HDMI and DVI ports, both no signal.
I then re-installed my FX6100 cpu and the video was fine.
Can anyone help? Is there some sort of compatibility issue with the FX8350 and the HD6950?
