well i got home yesterday and my computer was off.. when i left the house it was on.. so yeah didnt think anything of it and tried to turn it back on.. and it didnt work! i thought.. wtf? so then i tried using a jumper to turn it on where the power on switch would go.. still woudlnt work, so i swaped psu's and still to no avil. whats weird is when i put the connector half on the mainboard, the one from the psu, it powers up, fans spin but no post. is my mobo dead? or what could be wrong?
