problem: no video input

Question

Hello,

I assembled my new components: AMD 4000+ processor, 1 GB of Corsair Value RAM, 8600GT graphics card with an ECS (Elitegroup) motherboard and a 420 watt LC Power ATX 2 power supply. Once all the parts were assembled and connected, my black screen displays "Warning: no video input" at every startup and stays on this message.
The computer powers on, the fans are running, and the CD drive works. I checked everything but I'm stuck.
Moreover, I’m missing a cable for the motherboard power supply, but I read on a forum that it's normal...

That’s it

Your help would be appreciated

Thanks

You should already give us this information.

Then you talk about which “cable” of the motherboard?!?

Are you sure about your connections for the motherboard?

What type of memory do you have?

Regards

I have the "normal" startup beep, then the computer seems to start up.  if that can help you

Furthermore, I am talking about the ATX power cable; all connections are good and my memory is DDR2 (Corsair Value 1GB).

Why don't you plug in your power cable?!
And without your power cable, I don’t see how your machine could run?
Can you post a photo of your connections?

Hello,

I have exactly the same problem and I don't have any beep at startup, I've checked everything...

To begin with, last night I shut down my PC properly and today, it won't start anymore, no beep like before, the fans start to spin and it stays stuck on the same message.

I had already experienced this problem several times before and I always checked the connections, gave it a good blow to remove all the dust and it would restart after several tries.

Except that now it really won't start anymore, I checked (removed and properly reconnected all the connections, took out the CPU and put it back in place, removed the RAM sticks and tried them on different slots, etc...)

I even took my tower to try it on another screen and it still doesn't work, I did the same in the other direction (took another tower and connected it to my screen and it works, so the screen is not the problem)

I have a 8800 GTX 768MB graphics card and I also tried both DVI ports.

If you have any solution to this really annoying problem :(

To stay on Stanboost's message, the lack of a beep at startup could come from a bad contact between the motherboard and the processor.

Could the thermal paste between the cooler and the CPU play a role in this? (Could putting new thermal paste solve this startup issue?)

Thanks in advance to everyone who could help me.

Problem solved, it was the dual video card that was very dusty apparently...

However, I must have my hard drive that has given up the ghost at the same time because there's no more boot, and when inserting the Windows CD, I no longer have any data on the hard drive... (damn it)
Thank you anyway to everyone...
