Question My PC wont post after attempted GPU Upgrade

[MNBullsEyeBen]

A few years ago my dad and I built my PC.

SPECS:
CPU: AMD-FX6300 6 Core
RAM: 4 - 4GB Ballistix 1600MHz
GPU: Gigabyte Geforce GTX 750 Ti 2GB
Motherboard: GA-990FXA-UD3 R5
PSU: Corsair RX650

A couple of days ago I tried upgrading my Graphics card. I tried upgrading from the Gigabyte GTX 750 Ti to the Gigabyte GTX 1050 Ti. I checked to see if the new GPU is compatible with my motherboard, which it is.

My motherboard is able to support two GPUs; instead of removing my old Graphics Card, I placed the new Graphics Card into the second PCI Express 16 slot. I plugged the new Graphics Card into the power source. I reconnected my PC to the power outlet, plugged in my monitors to my old and my new graphics card and I pressed the power button. My PC powered on but my beeper did not beep (it beeps right after my OS was loaded.) and nothing showed up on either of my monitors.

I tried running my PC with my old graphics card, no post, just power (fans run, lights are on, disk drive runs.)

I tried to reset CMOS but that did not work. I tried everything and nothing works.

My Motherboard does not have integrated graphics and I could not find any lights on the board. The beeper was optional - I installed it so I knew when the PC would start up. -

Take them both out, unplug power from power supply, then push power button to "drain" any power residual. If you have a plain old no frills PCI video card attempt to boot with that in the first pci slot. No luck then try to boot with the 1050, no luck retry the old 750. Make certain that you are plugging in the power to the video cards (they need it in all, ie fill all the power connectors on the GPU card. When you install the card, do it while unplugged. Also did you clear cmos from the jumper? Are you able to access BIOS gui? The most powerful GPU must go into the first x16 slot on the motherboard... How many watts on the power supply?

Thanks for the reply.

I tried to clear the CMOS by removing the battery from the board. When power on my PC, I am not able to access BIOS gui. My power supply has 650 Watts
