The issue I am having right now is that Iíve assembled this PC twice and I am not getting any video. I have followed the process written in the sticky post but still no avail.
At one point early in the process, I was able to get the PC to post but at that time I had moved the video card to the lower PCI-express slot and the computer told me to move it back to the upper slot. After moving it back to the upper slot, the splash screen came up but froze there. Since that, I have been unable to get any video whatsoever.
I thought, at one point, that it might have been because I missed supplying power to the Auxiliary Graphics Power port but it still doesnít work.
Another possibility I considered was that none of the cables I have are any good.
I would like to use my 40Ē Samsung LCD TV as my monitor (this PC will be a media center of sorts). It will only allow two connections; D-Sub and HDMI.
I have a 6 foot d-sub cable that I tried using the DVI adapter supplied with my video card. I also tried this with my flat panel lcd monitor and a VGA monitor without success. It was this configuration, with the D-sub cable attached to the TV and the other end to the video card by way of the DVI adapter, that I encountered the brief video described above.
I also have this 6.6 foot DVI (male) to DVI (male) cable (Single Link, 18+1 pin)
This has also not been successful when used with my 19Ē flat panel monitor. Since I donít have a female DVI to male D-sub adapter, I was unable to try this cable with my TV or VGA monitor.
Just trying to explore some possibilities before I consider the card DOA.
I have searched the internet and realize that I am not alone with this video issue using the XFX 8800GT but no solutions have come.
Further complicating the matter is the fact that this mobo doesnít come with a case speaker connection, so I have been unable to even hear a post beep.
Hereís what I know:
The fans all come on (system, cpu, gpu, mobo fans), I can hear the Hare drive spin, the CD-RW spins, and the motherboard displays all of the appropriate lights. Just no vid when the PC is turned on.
Any bright ideas
