GTX 780 Graphic card does not work, Fan spins 100%! NEED HELP:(

[AnsonPoon]

Hi everyone, I recently ran into an issue. I have a Galaxy GTX 780 HOF for about 3 years, when I was using my computer yesterday, the monitor suddenly went black. I found out that its the GTX 780 that can not output. The intergraded GPU works.

Here are what I have tried to solve the problem:

-Unplug GPU from PCI-E X16 slot, reinsert into others slots.
-Unplug PCI-E power cables, reinsert.
-Use other cable for output.
-Boot in safe mode and uninstall Geforece driver.

Still not working after those solutions, I am thinking could it be the PCI-E power cable thats faulty? I doubt that but there is possibility. Apart from this I can not think of any other reason.
Or maybe my card is dead?

Please help..

card is dead or psu is failing? typical two issues

If the display output suddenly fails, it means the card is dead.

I think it should not be PSU failing, the computer is running fine using integrated GPU?
Will PSU only fail to supply power for PCI-E power cable?
