Hello,

Can anyone please advise.

I have built a new computer using a Asus P9X79 motherboard and a Nvidia GT640 graphics card, but when I to attach HDMI or VGA connectors to install drivers I get a 'No Signal' message on the screen (AOC e2239Fwt Monitor).

Any ideas would be most appreciated.

Thanking you in advance

Both connections do not work? Is the video coming through the motherboard?

And if I may, why would you have an X79 with a GT640....unless you are not gaming, which is a possibility.

Hi Deemo13,

Video thru Nvidia card no onboard VGA, and I won't be using PC for gaming.

Have you tried DVI connection? Have you tried a different pcie slot? Have you switched the monitors inputs to the corresponding inputs?



Hi Jallenlabs,

I haven't got a DVI Connector, also have set correct input settings and tried different PCIEx16 Slot.

This one?

Can you see BIOS or POST messages? Does it start to be black screen only when windows start loading or is it no video from the start?



Hi Sunius,

Link is the correct Graphics card.

There is nothing at all on the screen, goes straight to no signal then monitor switches off.

Do you have a good friend or neighbour who would let you try this card in their PC? It's a good chance it's dead on arrival.

does the computer actually do anything when you switch it on? like fans spinning, any beeps, hard drive activity?

you might have missed a power cable somewhere so the pc isn't even powering up itself...

Graphics card works great on another PC.

NB. I have noticed motherboard is displaying a code 61 (NVRAM Initialization) any thoughts.

Fans run fine, checked and re-reseated all components, but I have just noticed a Code 61 (NVRAM Initialzation) and thats it.

Is your CPU/RAM overclocked? I get that error code when I overclock too high.

Hi All,

May I first thank all who took the time to email me with there thoughts on my issue.

I have received a response from ASUS telling me that the M/B is faulty and to return it to the reseller. Will keep you up to date on the out come.

Once again many thanks for your assistance.
