The portion of the chipset that controls the PCIe slots is totally different from the fans.

Be sure the card is properly seated on the motherboard and the bus is completely in the slot. Be sure any power cables required are also firmly attached. Be sure in the BIOS the Video card is the primary graphics device.

If you have another system or a good friend willing to help take your video cards to him and try each one to see if they work with his system. Perhaps the issue is with your motherboard and not your video card. May be time for a new Motherboard.

I doubt this will help, but you may want to try it. Remove the gfx card. Turn off the switch on the back of the PSU and press the power button for a couple seconds. Then remove the 24 pin connector from the MB header and wait for a few minutes for any charge in the MB to dissipate. Plug the connector back in and insert the card. Switch on the PSU and see if the display will work.

Like I say, this is probably not going to work, but it is ever so slightly possible that a "reset" of the system might bring it back to life.

It's looking like a bad motherboard, perhaps a bad Bios or a bad Chipset. You can flash the Bios I don't think you can do much about the chipset. Perhaps you should consider shopping for a new motherboard. Can you still return the VGA card? Perhaps you can put that money towards a new motherboard.
