It's an older AT-style motherboard without ATX power connector. You will need to either find a working AT PSU or use an ATX one with an adapter.

The memory is in the first bank and needs to be installed in pairs (looks to be setup correct on your board).

Is this the right board? The layout looks very similar to your pictures.

I have an ATX to AT adapter 😊 and both EDO memory installed in SIMM1 and SIMM2 slot

Yes! This is SMT5TA jumper manual 😲

Although the JP numbers are not completely match, but it's really helpful 😀

Just a moment ago, I follow the jumper settings (CPU 3.45V) on the manual and connected the power supply to test this board, but when I turn on the power, nothing shows on the screen 😵
I am sure that CPU/Chipsets and SRAM will be warm when the power is on... I don't know why the screen and speaker have nothing output.

If you guys have any idea, please tell me, Thanks!

*The Graphics Card is S3 Trio64V2/DX
*I have tried different jumper settings but nothing happened...

could just be a bad board, if someone removed every jumper it may have been to add them to spare parts before getting rid of the board

No beep codes?

Do all the components work in other systems? If you know everything works except for the motherboard, then you'll at least know it's the motherboard.

Reseat everything and be minimalistic when running diagnostics (least amount of memory modules, no sound card, etc).

Reset the BIOS (you could leave the battery out for a while). I'll typically do 24 hours and spend the rest of my time on other projects.

Let's get to it. Start from start:

Push down any socketed chip (I am not saying to bend the motherboard). 😵 😵

Look for shorted caps, although I don't know if this apply to this Motherboard (I have been using
this trick on newer motherboards).

Push down the chipset (hold steady) and turn on the PSU. Doing so, you will known if there is
something wrong with the solder if you get to the POST (POST screen).
* Checking if the chips are getting warm is important, too, including the CPU.

Take out the BIOS chip carefully. Dude, you really want to know what you are doing here.
I have bent some of those chips along the way. When putting it back to the socket, put it
in the correct orientation (there is a guide, a mark on the motherboard and on the BIOS chip).
Maybe there is rust on the metal. but i didn't see anything (just a shattered label).

Just some long shoots. Good luck.

I hope not 😲 this board still looks good

CPU and RAM are fine, I think maybe is the chip on the board or power supply circuit have some problems (No any beep sound) 😵

I tried took out the battery for 24 hours and replaced the new one, unfortunately this board let me down again.

Good suggestions 😊 but the chips looks welded well (no pseudo soldering or short)

I think that BIOS IC more than 20 years old, maybe it's already broken 😢

Thanks for you guys replied, I tried many different way to boot it, but still got nothing.... 😐

So I use my voltmeter to measure the input voltage from power supply, the result is 4.88V and 11.89V (It should be 5V and 12V), maybe the voltage is too low resulted in the chips can't work?
(BIOS IC get 4.86V, PCI slot get 4.89V) (I tried give 5.03V to BIOS IC from mobile power bank, but nothing happend 😵 )

Nope, that's not it. This means the opposite, that your PSU (at least for the measured figures) is OK.

Good.

You are pretty good diagnosing motherboards. Could you please explain how to measure the BIOS chip ?

It should be equal or even 5% below or above (12V = 12.6V or 11.4V). I think only at 10% you should start worrying.

Someone throw a lifeline, cause I am out of ideas.

A bit of a long shot but you could try with an ISA video card if there is any screen output at all.
