Brothers rig dead?

[Xeonical]

For the past week I have been trying to get his rig to boot.

His specs are:

i5 2500k (never overclocked) Sabertooth P67 16gb G.Skill Trident Z 2666MHZ HD 6870 1GB XFX Pro750W PSU

What happened was he powered it on and there was nothing to the screen and yes I tried with different cords and another monitor but still nothing.

Upon opening it up I found that it was dusty as hell so I blew all the dust and turns out that his graphics card was getting no power so I tested his PSU, RAM and video card on my system with a i3 540 and a GTX 570 and they worked but my GTX 570 or my mom's HD 5450 don't work in his system and doesn't his 6870 even with 1 stick of my G.Skill RipJawsX 4GB 1866MHZ but his 6870 works in my system.

So I decided to take it all apart and reseat the cpu with and without the battery and still no power to his 6870 even with different graphics cards and RAM.

So I decided to resort to baking the motherboard and after that there was PCI-E power but the system still wouldn't get monitor power AND YES I MADE SURE EVERYTHING WAS PLUGGED RIGHT, USED DIFFERENT COMPONENTS AND A DIFFERENT MONITOR AND WIRES.

Since the motherboard now gives PCI-E power I think that it may be the processor, what do you guys think is wrong?

Is it possible that all the dust that he let excessively build up cause a static damage?

Should I try a different PSU with his system just for the heck of it?

I probably would have done that before baking the board....

I'm willing to bet the board itself is bad and most likely the cpu is fine.

I'd bet on it being a bad board.
