Stumped - Mobo Issues - Erratic POSTs

[Sammy5000]

Hey Guys...

I am running into a developing situation with a new rig I am building. Here are the basic components I am using to test if this thing POSTs:

Shuttle AK31 Mobo V 2.0 (VIA KT266A Chipset)
AMD Athlon 1 Ghz CPU (100 FSB)
Ti4200 AGP Video Card
1 Stick of 256MB PC2100 (Samsung)
20GB HDD Maxtor (Master)
Floppy
Enlight 300W PSU

Ok. That is all the components I have hooked up right now to test. I just wanted to get it to POST consistently. The problem I am running into is that when it first booted, I got long, repetitive beeps which leads me to believe it is a memory problem. I would reseat the RAM in the same DIMM slot, same thing. I would move it to 2nd DIMM slot, same thing. I would move it to the 3rd DIMM, and it would POST, so I would go into BIOS, and change some settings, etc, but then, after a minute or so, my keyboard would no longer work, as I could not manipulate anything in the Bios?

I would re-boot (without moving memory) and then I would get the consecutive long beeps again. I would reseat it in the 4th slot, and it would POST again, let me go into BIOS, and the keyboard would go again.

Then, I moved the one stick of memory back in all of the different slots again, and it would POST every now and then and do the same thing (keyboard would go after a minute), etc, etc, etc.

The beeps keep on going when it doesn't post - no shutdown. I do believe it is memory related, but since I only have one stick of memory, I cannot test that. Unfortunately, I got this mobo and one stick of memory from someone who said it was working.

Any thoughts???

***** UPDATE ***** : I placed the memory stick in another rig and it was recognized just fine. So now that I know it is not necessarily the memory stick, I am really lost!!!

Sounds like you can get to doing things when you reboot, witch makes me think that the cpu is cooling down enough for you to do things then it gets hot and stops working, I do not know much about the mother board that you are using but it might have a fail safe that if your cpu gets to hot it will shut down and will not start in tell it cools down to low temps. Maybe reset c-mos bat and make sure that the heatsink fan is running and that the heatsink will support that CPU you have it on.

This Mite help, Mite not. Good luck and keep up with the updates.

I am not sure it would be heat related, just because of the long, consistent beep sequences. It the CPU was overheating, then it would just shut down/crash without the long beeps every other time or so.

I have reset CMOS a few times to no avail.

Do you have any spare ram sticks/mobos/cpus compatable with the other parts? you should narrow it down to which component is the faulty one if u can. if not, this may take more time then needed otherwise
