I would try a couple things at this point. First, remove the CPU and inspect the socket for bent\damaged pins.
Leave the 1050 TI out for now.
Then, manually reset the BIOS.
To do this, follow these instructions:
- Disconnect all power sources: Power cable, video cable, powered speakers, etc.
- Press the power button to discharge any residual power in the system (I am serious)
- Remove the coin-cell battery (note which side goes up)
- Wait at least 1 minute.
- Replace the battery and reconnect the previously removed connections.
- Power on.
