So I sold my brother my PC last night and when we went to move it to his room it wouldn't boot. we didnt think much of it because we planned on rebuilding it in a different case of his choosing. After we bought the case i tore down the computer and set it up on a make shift test bench on the mobo box and not only am i not getting any power leds on nothing is happening i cannot get it to boot to bios. i have tried two different power supplies and with and without ram and Video card. is it possible that my motherboard is dead?
Specs:
Asrock Z97 Extreme 4
Intel i5 4690k
Corsair Vengance 16gb Ram (4sticks)
R9 290 Vapor-x
EVGA 750 G PSU
Any feed back will be much appreciated!!

I sure hope you told your brother there would be no warranty on the computer. :p

Just kidding. I do agree it sounds like the motherboard has died. I am assuming that you have disconnected, and reconnected the 24 pin connector, and the 4 pin or 8 pin motherboard power connectors. Sometimes, thats all it takes to get them going again.

Just read your explanation of what happened.
I tell you from experience I have known computer or tower systems not to work once they have been moved.
I know, or have seen a few reasons why a board may power up for a split second or fail to power up after it has been moved.
The result is heat or should I say expansion of components.
Key culprit is often the bios chip if it is set in a brown type socket. They tend to shift in the socket with heating, expansion and contraction of the mother board, and when moved or jostled become slightly loose in the socket.
Causing some systems to power up but no bios screen or boot is exhibited, or as said a split second power up and shut down. but also a state where it produces an error in the Psu unit tripping a protection circuit.
That has to be cleared by turning the rocker switch off on the unit, removing power then turning back on at the wall and switching the rocker switch to it`s normal power state mode.

It may work, just push on the bios chip in the centre of it, if it clicks or creeks it may be it has just worked it`s way out enough to cause a break between the chip and the pins of the bios socket.
Apply your power making sure first you have re set the power supply in the way explained and see if the board posts.

On your board it is the two chips in the sockets close to the Sata ports and the led, hd,power, power and reset switch header of the board.
