HELP!!!!

About 3 weeks ago my PC stopped booting up. Power seemed to be
travelling through all components, lights were on, fans were whirring,
but nothing was happening on the monitor.
I thought it was my Graphics card. I have a GE Force FX5200 and a
Gigabyye GA-8 SQ800 motherboard. I swapped the graphics card for an
old 32MB card I had lying around and everything started working fine.
I bought a Sapphire ATI Radeon 9600XT 256MB and decided to try this
instead.

I swapped the graphics card again and the original problem reoccurred,
power all the way, but nothing happening on the screen, PC didn't boot
up.

I'm now pretty sure this is something to do with the Motherboard, has
anyone seen this before??

Any help would be greatly appreciated, I don't fancy having to chuck
more money away on a new motherboard!!
