Question Graphics card fans not spinning, high pitched noise, no display

[Bill_Skills]

I bought a Dell Optiplex 960 SFF and added an EVGA GTX 1050 SC 2 GB using a PCI-E 16x riser cable. The PC worked for a few days but now the graphics card won't work. Right now, if I connect the graphics card with the riser cable to the PCI-E slot, then connect the power cable and power on the system, these things happen:

• The graphics card emits a high pitched noise.
• The fan either spins or doesn't spin (Sometimes it does, sometimes it doesn't).
• According to Dell's Optiplex reference guide (https://www.dell.com/support/articl...ex-diagnostic-indicators?lang=en#2009_to_2012), the diagnostic lights on the Optiplex say I have a graphics card failure if the DVI cable from my monitor is plugged in; if I don't plug in the DVI cable, I get a possible system board resource and/or hardware failure.
• The card doesn't display anything on my monitor.

The system still works when the card is removed, I just plug into the integrated VGA port.
Any advice on what to do would be greatly appreciated.

What you have is dead GPU and there is no point trying to "repair" the dead GPU. With that, only advice we can give to you is that you replace your GPU. If you have warranty on it, RMA it. If not, cut your losses and buy a new GPU,
