I wanted to plug everything onto another motherboard from my old pc to see if my gpu would work there but gave up after i had no powerbutton on that motherboard,and i put everything back in,plugged back the cables and it showed no signal on integrated graphics and the gpu is not plugged in,full pc spec psu thermaltake 550w liteseries,i5 4460, asus h81m-r (motherboard),some Kingston 8gb ram and gtx770
