No video signal (AGP or PCI) on ECS K7S5A

[PCDumbass]

For some reason, I am not getting a video signal on my used ECS K7S5A.

Both of the tester vid cards are good - I tested the PCI and the AGP on my reference system, they work fine - and the MB seems to start up fine, the CPU fan runs well, the HDD led lights up and the CDROM light also flashes. I have tried two RAM sticks that work in my reference PC, with the same board, and no change.

Now, I am running a barebones system with no floppy and not all of the MB screws are installed. I hope this wouldn't make a difference.....but I'm curious as to whether the MB uses one of these screws specifally for it's main ground or something.

In short: I have no video signal from the PCI or AGP ports when using a working PCI or AGP video card.

Any ideas?

Did you try clearing the CMOS? Either there is a jumper, or just take out the battery for a few minutes and turn on the computer. Also, is the CPU getting really hot after a minute or so of having the system on? Can you test the CPU on another system? The mobo doesn't use any screws for grounding, you don't even have to have the computer in a case(definetly not recommended though😀) and it would work. Otherwise, I'd say you got a dead mobo. Good luck!

Might be a shot in the dark...but what about the monitor?

Make sure the Agp / pci card is seated all the way, also I'd take the whole system out of the case and put the motherboard on a static bag so you can rule out the posibility of the motherboard being grounded. Hope this helps... 🙂

Possibly a dead mobo too which is unfortunate.

Hey man, I posted in your ECS K7S5A thread too.

I did two other things last night:

1) Swapped in a PSU from a working system I have that is running an ECS K7S5A as well [Didn't make any difference]
2) Swapped out the BIOS chip from a working system I have that is running an ECS K7S5A as well [Didn't make any difference]

It still won't beep upon booting, I'm pretty convinced she's dead as a doornail.

Yes, I reset the CMOS and then put the jumper back in the stock position, still made no difference.

I'm going to pull the Duron and try it in another system tonight, with the same board just to make sure it's OK.

Now...my next question:

When I received the board, there was no jumper on JP4, which is the jumper panel used to reset the board. There is supposed to be a jumper on pins 2-3 for normal operation, and you can put the jumper on pins 1-2 if you want to reset the CMOS. WHat would happen if you tried to boot up the board without any jumper on JP4? I'm thinking this might be what fried the MB.

Thanks to anybody for any replies to this Q.

I verifed the monitor on another system, it works perfectly. Thanks for the tip though.

yes, the vid card is seated correctly. I've built several ECS K7S5A and I'm aware of the very positive "click" it requires for correct installation. I've tried a PCI vid card too, no difference.

That could be it. Try putting a jumper on pins 2-3 to see what happens. Otherwise I'd say it's dead.

Umm, doesn't the outside layer of static bags actually conduct static electricity as part of the way it keeps it away from the stuff inside??

That would make it a bad thing to put a board on for testing. I could be wrong, but I always thought that was how the static bags worked.
