ECS K7S5A will not POST, no beeps either

[Oakenfold]

Listen to Buzz2b I've seen him around more than one K7S5A board.
Definetley take everything out of the case and lay it on an ASB, mobo,video, one stick of ram only.
Start from there, leave the cmos in a cleared postion for at least 5 minutes(that is just theory, it never works for me unless I leave it alone, I think the mobo likes being by itself or something)..

Also try it with another proc if you have one.

Buz2b's the man My K7S5A had precisely the problems he and tennesota describe. The DIMM was getting high-centered on the key in the DIMM slot, for one thing, so take a close look to make sure on that. The AGP slot has two rows of contacts, and I could hardly believe the force needed to initially get all the way down into the second set. If you can see the gold contacts where the card meets the slot, then it's only halfway down. A film of petroleum jelly on the card might help if it's scary-tight.

Good luck!

I have the exact same problem - the difference is that my computer has been up and running for over a year. Then one morning, I see that my computer crashed (blue screen), hit the reset key and again it got the blue screen. I then powered it off, upon powering it back up, I get the same description as below. Tried many times resitting the agp vid. card and ram, but to no avail.

any suggestiosn?

I've read in other forums that the trick is to change the bios but how can you change the bios if your computer is not booting? any help is appreciated.

bump!

I actually really like this board.. awesome for the price. A few things you MUST check though:

1. CMOS jumper comes set to "clear" it seems. In doubt, try it the other way.
2. Power Button / Reset headers: these are mislabeled in the manual, and confusingly labeled on the motherboard. Good chance you've got the power button header on the wrong pins.
3. AGP card properly inserted? Try pulling it out, reinserting it. I'd recommend building the system outside of a case first, on a large anti-static bag. Once it works, put it in a case. You can also avoid shorts this way.
4. Still no luck, pull the CMOS battery and put it back in, then try again.
5. Remember, only one type of ram at a time - don't mix DDR and SDRAM. If possible, try the other type of RAM if you're having problems with your RAM, it could help. Reseat the ram maybe.
6. Power supply. I recommend the Antec TruPowers for this, because I know they work. I'm using a 330watt, 80gig, 800mhz Duron, and SDRAM with an ATI AIW7500. No problems.

Mine booted up the very first time! But #2 on my list had me scratching my head for about 10 minutes ...

Very impressed with the board for the price ...

These things happen when (a) the power supply unit is inadequate or has died (of constantly being on the edge, mostly) or (b) when the CPU fan isn't spinning fast enough or doesn't provide a proper rpm signal to the mainboard ... or is plugged into the wrong fan header.

me too! built a system for my sister over a year ago, had many of these problems initially, but solved all and has been working fine for a little over a year. then the otehr day i get a call and was told it can't get to windows, then again later that it won't get passed ram, and by the time i got it to my house and plugged it in, no post at all. no beeps or warnings either. i even tried a different battery. i am going to pull it out of the case and see if it was just shorted out as soon as i am done posting this, you will hear my results if it's successful. but any suggestions would be appreciated.

didn't work

Some might be interested to know that the K7S5A has a very common problem that occurs when someone is using a modem with an ESS chipset. Namely a system containing a modem with ESS chipsets will not boot, period. A K7S5A System will NOT boot with a modem containing some (maybe all?) ESS chipsets.(a.k.a. a good chuck of Creative labs modems) No matter what pci slot it is in. I don?t know why, but I've seen the problem firsthand on a half dozen systems and it happens every time. To bad since creative sells several low cost non windmodem options.

A common symptom is the ability to run a 100 MHz bus speed ... ie an underclocked Athlon but not at 133/133.

If you change the bios to 133/133 and start it with a modem it in it will take a couple restarts for the system to be able to boot to video in 133/133 after the modem has been removed. Very peculiar.

ECSs response to this issue is to simply get a new modem.. ugh. I have yet to find a firmware upgrade or bios setting to fix this for the modems or the mainboards. Go to windows device manager/modems and do a diagnostic to find the exact chipset your modem is using.
