I have just installed a new GPU into there I did not have any other GPU in thereYou just installed that GPU in that system? What GPU did you have before?
What is your PSU brand and model?
I looked at the power supply and it does not have a model nameEVGA is the brand, 500w is the wattage and 80+ is the efficiency. We still need the exact model of the PSU.

it says 100-249vac 8/4a 50-60hzThat's impossible. The PSU has a sticker on it that says the wattages and the voltages and on that sticker you can see the model number.
Should look something like this.

I was able to start up the computer with the GPU but after logging in it shut down on its own and I cannot get it to start up with the GPU againThat's impossible. The PSU has a sticker on it that says the wattages and the voltages and on that sticker you can see the model number.
