Things I've tried (with obviously no success):
1) disconnected all drives
2) removed/reseated RAM (only one stick so I couldn't put in different slots, etc.)
3) moved fans to other fan options (cpu to fan1/fan2, fan3, etc.) - (per Pauls Unofficial KT7A-raid FAQ here:
http://www.sudhian.com/showfaqs.cfm?fid=2 )
4) ran system by itself on it's power strip (y'never know)

I haven't yet tried cursing and screaming at the system, and I'm not sure why considering my part-time video production income depends on this running!

Also, I'm not positive but I think some storms came through our area last night. I'm kinda wondering if this might be surge-related? My guess is not since everything else seems good and the system was running this morning. But I don't know.

ANY HELP?!?!?!?!?

 

[Rick Hallman]

Is the computer completely silent? Any error beeps? Do the fans begin to spin or any other component show that power was applied briefly? If all of the above are no then I would try to use a different power supply to see if you have a PS issue. If a different PS doesn't help then I'm afraid you have a component failure on the motherboard.

Good Luck

I have a KTA-Raid also.

Try another CPU fan on it, i think the deafult it to turn off if the fan isnt spinning

Tried using the CLEAR_CMOS jumper?(find it in the manual, It might have a slightly different name like C_CMOS).

If not;

disconnect all power, put the jumper in the 2-3 position, wait a few seconds, put it back in the 1-2 position, and try powering on again.

Hi db

I had the very same problem, got some old caps from my friends DEAD BP6 1500uf 6.3v. Fixed it for a while then it mashed my HDD thanks.

IMHO gat a really big hammer and smash it to bits !!
This will save weeks of frustration and releve some tension at the same time.

For those first .5 up to 2 seconds, everything fires up - all the fans included (first thing I checked). There are no error beeps to start, only if a remove the RAM or unplug the CPU fan, etc.

Does it sound spike-related? If so, I'm contacting my insurance right away!

Well, the fan IS spinning, but I guess it might be UNDER-spinning, but it doesn't sound like it's having problems. But I'm thinking it is a safety-check like that, unless something on the board is shot!

I bet the screen saver is a red herring since its operation is quite removed from the boot process. How far into the boot process can you get? Does the bios load? Have you checked for swollen or leaking caps? Reportedly the ones adjacent to the AGP slot are often the first to go. Do you have a known good power supply to try?

...

Interesting that you mention leaking caps. Of the two suggestions I received thus far on this, both have stated the caps as being a problem for this era of Abits. I haven't looked yet, but I sure will. And as far as the boot goes: it doesn't. The power comes on, the power goes off. It is on long enough to wake up the monitor, but nothing makes it to the screen.

Well, fortunately or unfortunately, I see no visibly bad caps. Obviously that doesn't mean one of them can't be bad, but I can't rely on it either.

Any other suggestions? Does it sound like a power supply gone kaput? Does it sound like a spike-related problem (lightning)?

 

[Sling]

How about a CMOS clearing? Perhaps something got messed up with the CMOS durnig the storm and now the BIOS is trying to do something silly like booting your CPU at 5x100. My KT7A did the same thing when I was fiddling around trying to get the CPU to boot at different settings. Normally when it goes ON then OFF in a split second it normally is due to the CPU fan not being connected to the MB, but have you tried plugging in a different fan (assuming you have one) into CPU FAN1? You never know, the fan may be running but the motherboard doesnt know it is....

If you can, try swapping out the keyboard and mouse. I had a similar problem, only on a much older machine (it was a cyrix 150+ processor, quite some time ago), and it turned out to be something weird in either the keyboard or the mouse (I don't remember which, I bought a keyboard / mouse combo to fix the problem). This doesn't seem likely with newer systems, but it'd be an easy try (just unplug them both)

Kinda goes with the screensaver that wouldn't come on.

 

[Rick Hallman]

Since you do not hear any beeps then motherboard never saw a problem before the power supply shut down. If the motherboard shut down on a CPU Fan low RPM error then you would have heard a long beep before it powered down. I know this because I purchased a "quite" HSF for my KT7A-Raid and I received the low RPM beep before it would shutdown. (This setting is switchable in the BIOS but you have to plug in a faster fan with RPM sensing before you can get to the BIOS settings to turn it OFF.) I think the logical step for you to take is to borrow a known good ATX 350Watt Power Supply and plug it into the motherboard, floppy and HD. If your computer still shuts down in 2 seconds then try clearing the CMOS with the AC cord disconnected. I have had some glitches in the past where I had to clear the CMOS and disconnect the AC to completely recover from a problem. You will need to enter setup as soon as the BIOS screen pops up and set your CPU speed, along with any other settings that you have optimized in the past.

I hope this helps.

While this may be a caps problem I have never had the luxury of a bad caps board so I wouldn't know.

What I have seen that resembles this is:-

1: Sticking power switch. Would press it and it would always stick in the on position which would then switch the board back off again.

2: Motherboard not reading the CPU fan rpm sensor correctly. The board would "think" that the fan had stopped and shut the board down. Fixed by using a different fan.
