Hi all. A few days ago my system stopped powering on. Specs below. 

It would simply do nothing when the power button was pressed. I opened it up and tested the MB power cable in my PSU test unit. Power supply came on, fans came on, voltage showing on test unit. Plugged it back in. Still dead. 

Removed parts one by one until it would boot. Removed video card and it booted up to POST beep. Retried, same thing. Tested another video card. Dead. Tested another video card. Dead. Retried original video card. Dead. Retried booting without video card. Nothing?!? 

Right, now it won't boot at all, but when I flick on the power switch on the PSU the motherboard power and reset buttons light up (there are small power and reset buttons right on the MB) but do nothing. I now have it stripped to just MB, PSU, CPU/FAN, still nothing. I'm almost positive its the MB, but I need to be sure if its that or the CPU before I order replacement. Any ideas would help. Thanks.

Motherboard - Asus P6T
CPU - Intel i7 Quad core
Video - ASUS EAH4870 DK/HTDI/1GD5 (ATI Radeon HD 4870 with Dark Knight Cooler)

:welcome: Max20 to Bleeping Computer.

Aside from the Motherboard suspect, have you tried a different or borrowed a good known PSU just in case?
