Install Help! - GTX 1050ti & Gigabyte GA-P75-D3 not booting

[bmcdonald7]

Ok so I can't get my PC to boot up with my new 1050ti Graphics card. I have a 3 year old iBuypower PC and I was looking to upgrade the older GTX630 graphics card I have in it. I only have a 300w power supply so I did some research and saw the 1050ti could work with 300w power supplies with no additional power connectors other than the PCI slot. I bought the card and attempted to install but the PC only boots up to the BIOS screen and stays there beeping every 30 seconds. None of the BIOS commands work. I realized I forgot to get rid of the old cards drivers so I put back in my GTX630 and it booted up no issue. I ran a driver cleaner software deleting the old drivers and shut down. Attempt 2 and same thing. It boots up to the BIOS screen but stays there beeping every 30 seconds. I'm at a loss what to do. All the research I did says they should be compatible. Any help or suggestions on how to trouble shoot this? Thank you!

System:
Intel I5 Processor, running 3.8GHZ
8GB DDR3 ram
Gigabyte GA-P75-D3 motherboard
300w power supply

Thank you!
