If no signal to display, likely gpu problem. U have to verify if this. Swap the display cable first, just in case.

I have already tried replacing the CMOS battery, reseating the ram

The keyboard and mouse lights up but the issue still the same

If it's not the ram, it's likely your cpu/gpu. run the system without your external gpu, see if that triggers the boot. if it doesn't, it's highly likely the problem is with your motherboard.

I don't hae any external GPU. How is it possible for me o test the mother board for failure now.

Basically can be summarised as no beep, no display , no bootup

He meant using the vga port of the mobo.

Unable to boot up, I try all the display ports already

Plug back in.

if it used to beep when working,
then now got power but no beeps at all with ram & gpu removed, even when swap to known good psu
i suspect cud be mb...

 

[hawthorne]

Yes. Likely motherboard. If u remove everything except processor, the motherboard will have continuous discrete beeps to signify no ram. If that also dun have means Mobo problem

Of course u must plug in a buzzer in the speaker lead
