Replaced capacitors but still no go

I replaced 4x TAYEH 2700uF 6.3v capacitors that had blown their tops but the motherboard is still no go

What gives?

The PC speaker makes a strange creepy noise (if anyone's seen the movie "The Grudge" you'll know what I'm talking about).

The cpu checks out fine in another motherboard, so does the psu, so does the ram. I've wiped the BIOS settings, but that doesn't help either.

Any suggestions would be a real help!!

Thanks
