I've had this prebuilt pc for a while. I got it from newegg but unfortunately I can't find the link to it anymore so I can't give specs for the motherboard (unless you can tell me where to look on the motherboard that says it) but the graphics card was a Zotac Mini GeForce GTX 1050. It had 8GB of RAM which I upgraded to 16GB with no problem. Recently, I wanted to upgrade the 1050 graphics card to a 1070. I got myself a Zotac GeForce GTX 1070, and I took out my 1050 and installed the 1070 and plugged in the PCIe power cables but now my computer won't turn on. I've tried putting my 1050 back in but it isn't working either. I had my computer off (of course) but from what I've read I probably should've unplugged the power cord altogether. I've tried my hardest to get it to come back on but no luck. When I unplug it and plug it back in and try to power it on it makes a faint clicking noise and the light on my fan turns on for a split second then instantly turns back off. It doesn't matter which card I use. When I try pressing the power button after I had pressed it after I unplugged and plugged it back in, It doesn't do anything.

If anyone can please share anything that might help it would be greatly appreciated.

The motherboard should have the model printed on it around the center of the board, but being a pre-built, there's a slim chance it's proprietary.

For a pre-built that came with a 1050, the PSU was probably only ~300W or so, and potentially not a very good one.
The 1070 adds another 75W power draw over the 1050..... If your PSU was pretty poor to begin with, it may be fried.

Unfortunately, not a lot we can determine without specs.

Which CPU? Motherboard number if you can find anything? PSU name/model/wattage (should be written on the side).
