Is my graphics card defective or my pci-e slots/motherboard

[Cesar1016]

Hello I'm having problems with my PC. Four days ago i built my first pc and it work perfectly the first day for about 2 hours of installing programs and updates/drivers and about 1 and 1/2 hours of gaming and 2 hours of web stuff. then the next day when i turned on my pc it would not boot the pci-e led staid on. On board graphics work fine gust GPU not working.

(PROBLEMS FROM GPU)

*wont boot with post led on for pci-e
*boots but wont display on monitor/ GPU fans spinning.
*boots with display half way through boot, then display disappears.
*fully loads but then display shuts off at log in or 2 minutes in .
*fully loads then display shuts of randomly.
*fully loads but with purple flickering on half of the screen .
*using gpu-z core/memory clock, temps,load and volts all spike up on idle.

(WHAT I HAVE TRIED)

*switch to different pci-e slot.
*re-install windows and drivers.
*unplugging,and plugging wires back in to all components.
*made pci-e main graphics in bios.
*made shore every wire is in correct.

(system specs)

*PSU: XFX PRO 850W Black Edition.
*CPU: Intel Core i5-4690K.
*GPU: gigabyte gtx 780 GHZ.
*Ram: ADATA XPG V1.0 8GB (2 x 4GB).
*Mother board: asus z97-a.
*Seagate Barracuda 1 TB

Thanks for reading and sorry for it being so long need to now asap.

So do i rma the card and mother board or because I'm still under Newegg 30 day refund shoud i just return it and buy a EVGA 03G-P4-2782-KR GeForce GTX 780 because in review people are having problems ans saying that gigabyte gtx 780 GHZ factory over clock is too high

exchange the card because the motherboard is working fine without the the card....but still if u have doubts about your board exchange it too because you have both them together...so should be no problem replacing them.....too high oc doesn't matter u can always underclock that to your comfort zone...
