Fried motherboard?

I have 6 year old pc and recently i cannnot get it to boot. When i start it up all fans and everything start up but no display. I took my 250Gt out and plugged my monitor to the integrated graphics and still nothing. i also tried another monitor and still nothing.

In order to turn off my pc i have to unplug it. when i try to power down the pc holding the power button it just makes the fans go insanely fast.

Ive tried tried the No post No Boot No video output checklist http://www.tomshardware.com/forum/261145-31-perform-ste... and still cannot get it to work. I know this is a hardware issue just need to figure out what i need to replace.

Any help is appreciated. Thank you
