Integrated GPU works, dedicated GPU doesn't

[Crackzack]

So recently i sent my mobo to be repaired because it was faulty and i had warranty. The servicing center sent it back claiming fixed. Sure enough my pc turns on. Yet when i plug in my dedicated graphics card (r7 260x2gb ddr5) the monitor does not get any display. But built in integrated gpu works.
So, is my graphics card also faulty? Should i sent the graphics card to repair while i still have the warranty?
Thanks in advance.
Specs:
Core i3 4th gen.
8bd ddr3 ram.
450w brand PSU. (forgot the brand name. probably thermaltec/gigabyte.
gigabyte h81 motherboard.

Might be a dead gpu, might be dead pci-e slot, might be your psu or even your cabling.

Check the 6pin connector first and make sure it's not loose or anything.

Does your pc boot up when the gpu is attached? There's cases with dead gpu that it will cause the board to not POST. It's harder to tell if pc boots up fine without display output, but you can watch the sata activity led.

If that's the case, you'll need to test your gpu in another pc. If that pc fails to POST, then you can safely assume your gpu is dead. Otherwise the problem's in your board or psu. There are instances where a defective pci-e slot showed symptoms same as a dead gpu, so you shouldn't rule out anything.

i know it sounds stupid, but i made this mistake many years back, so offering this advise
the thing is, did u plug the hdmi cable into ur gpu after connecting it or did u keep it connected to your mobo's gpu? try re-plugging and see if it fixes anything.
if that wasn't the case, sorry for this post

I have had the same problem and it took me months to figure out I plugged in my DVI-D plug into the DVI-I slot instead of the other one. The gpu didnt post while plugged into the wrong slot. You're not alone.

I would advise the OP to check whether all the display cables are plugged properly into the graphics card and also the monitor.
