I was hoping you could please help. Ive just upgraded my Nvidia 8800GT with a Radeon 6850. Ive clipped the card into the motherboard and attached the two 6 pin pci-e connectors via molex adaptors which came with the card. The problem is upon booting up, while the fan starts to spin on the card and everything seems operational, im receiving no image on the monitor.
I reconnected my 8800GT which runs on a single 6 pin pci-e connector and the image appears perfectly fine.
What could the problem be? In the back of my mind im thinking maybe my 500W PSU isnt able to supply enough power? But if this is the case, is this the sort of problem you would come to expect?
My system specs are below and ive included a few pictures of my set up as well as of my PSU so you can see the power ratings etc.
