help with mainboard beeps

[mrlugal]

I'm building a new computer system with an athlon xp 1500 + processor and ECS K7S5A mobo. I suspect that either the motherboard or processor is bad, but am unsure how to tell which. I don't have any other compatible parts to test it out on because this computer is a socket A and my others are socket 7's.

Here's basically what happens:
When I boot up the computer, the fans run, but nothing else happens. There is no video signal and I don't get any warning beeps.

If the motherboard is working, shouldn't I be getting beeps of some kind? If the processor is not working, or not plugged in, should I still have warning beeps?

Thanks for any help.

Might want to check your ram while you're at it - I had a hard time fully inserting the ram into my K7S5A - I was afraid the board would break (because it was bending so much).

See if they're in the right slots - I had a friend accidentally put his ram into slot 2 instead of slot 1 and it wouldn't boot because of that.

I just hope you didn't accidentally crack your core putting on the heatsink. I was afraid of doing that too when I put on my HS too.

nope, I was very careful when doing both...

Are you running with the bare minimum of components? I had a NIC that was causing my system to just power on with no POST and no beeps. I would try running it with only the CPU, RAM, PSU, HDD etc.

I only have the ram, video card, and cpu connected.

I've tried all the different combinations of those as well as subtracting all of them. Still no beeps. Only the fans powerup. It makes me think that it's the mobo.

What do you guys think?

Remove it from the case to make sure it isn't grounding out anywhere. (VERY common) Also, make sure the video card is inserted firmly - that board has a known problem with cards not seating well. Do you have another powersupply you can try? Again, that board is known to be pickey bout them as well.

Make sure you have a really good powersupply. The tech support person for ECS suggested to me to use a PSU with at least 28 amps on the +5 volt channel.

I tested a different power supply....

I also checked to make sure it wasn't grounding (it definitely was at first, because I couldn't get any power at all), but I suppose I could try it again.
