Hi. i am having a strange problem. I am trying to get this figured out before my AsRock Mobo $30.00 rebate expires. I am holding off on doing it until I am sure the problem is not the motherboard.
Corsair RM1000
X99 ASRock Extreme 4
x99 5960X intel
G.Skill DDR4 32gb
Corsair H100i
Here are the video cards I've used.
780GTX (takes external power)
480GTX (takes external power)
GTX7950 (does not take external power!)
MSI GTX card (probably 670?) (takes external power)
Monitors used.
Dell 30 DVI
Dell 2007fp DVI and VGA (converted from DVI out of PC)
Samsung TV (HDMI on 780. DVI. and DVI converted to VGA)
I have tried a lot of configurations and test. The computer will put out video when converting DVI to VGA on the big cards (780/480 etc..) and that works on TV and the small Dell. This is finicky though! I have had times where it will not work after trying to log into windows (when it probably changes resolution). I have had it stop working in the middle of using the computer. I have had it work fine for a long time. The machine runs great. I even ran Passmark while in 1920x1080 over the VGA on the TV once.
I can usually get a Bios Post out of this configuration.
ONLY the old (non external power) 7950 card will work DVI to the Dell 30 inch.
As far as I can tell ALL of the big cards will not put out anything else! HDMI or DVI across anything. No bios post. No nothing.
I have tried hooking up (using the paperclip trick) another power supply to the 780. But that power supply might be bad. I have no real way to verify.
I have tried other PCI-E slots
I have tried all new PCI-E wires and moved them to different slots on the RM1000.
What could the culprit be? Could it even possibly be the motherboard? or is that highly unlikely? Could it be the CPU? I am inclined to think it is the PSU but it is running everything else perfectly and I cant even get a Bios Post out of hooking up the external (paper clip'd) unit.
Thanks.
