Gigabyte GTX-770 not showing display..

[Terno]

Hi!

So the problem is that me and my friend took this GTX-770 off from my friends computer and then we put it back. We set the card correctly to the motherboard and connected the 6+8 cable, but when we pressed the power button the GPU's fans started to spin REALLY fast and didint give us any signal to our 24'' monitor.

So we took the card off again and put in an another card (Radeon HD7850) and it gave us signal to monitor.

Do you guys got any clue why is this GTX-770 doing this.. I mean we just took it off for like 15 mins and then put it back and it didint work anymore. We also tried the GTX-770 on another computer and it did the same thing (fast fan spin and no display)

We have tried all the other video outputs from the card and all the other components are working in both computers we used to test this GTX-770

We also plugged our monitor to the motherboard integrated GPU and checked from the device manager if windows can detect the card, but no windows couldnt detect the gpu.

PSU: Zalman 700wat
RAM: Kingston HyperX DDR3 1600mhz 8gb
CPU: AMD FX-4100
Motherboard: Asus M578L-m lx

And the other computer we used:

PSU: 450wat (cant remember model)
RAM: DDR3 1600mhz 8GB
CPU: Intel core i5-4670k
Motherboard: Gigabyte Z86X-OC

All help is appreciated =)

Even without drivers the card should be outputting a signal, so that cant be the problem.
Have you tried setting the graphics driver in the BIOS to PCI?

Have you tried another PCI lane?

On the M5A78L computer there is no other PCI lanes but on the Gigabyte Z86X-OC we tried all the other lanes and it didint work.
