gtx 1050 Gtx 1050 won't work

[Jobradov]

So i bought a gtx 1050,unninstalled my drivers using ddu.Installed the gpu.Fans continously spin but u hear in a delay of 2-3 seconds that some fans stops and starts again.Probably psu.So i grabbed my other psu tried with that,the same problem.I unplugged everything just the cpu and gpu,same.Everything works when i put my r7 260x,it boots up.Its the Gpu thats faulty?What can i do to fix it somehow? The specs are:xeon e5440,4gb ram,ms 7529(g31tm-p21)Idk is it the old motherboard that cant push enough or what?Help please The gpu isn't open its like brand new .I took everything from the case and put it on carboard from the gpu still the same.I can't think what to do.

Could be the motherboard that doesn't provide enough power through the PCIE slot.
