Question My PC Will No Longer Boot

[SPAWN of II]

Before I begin, my specs are as follows...

Asus Gtx 1060 6Gb
4x4Gb DDR4
500Gb SSD
1Tb HDD
Corsair CS650 M

About a week ago, I powered on my PC as usual and got an alert in the BIOS that the motherboard had detected a power surge from an unstable power supply. I was slightly concerned, but I had just ordered a new, higher quality power supply the day before. I continued through the BIOS and noticed no problems. Everything was running smoothly, zero issues. For the next few days, I continued to use the PC as normal and everything worked as normal. Although I kept getting the alert saying the motherboard detected the surge, every other time I turned the computer on. When the new power supply arrived I installed it immediately, but the problem remained. I tried different surge protectors and outlets, but nothing fixed the problem. I did start to notice some weird things happening though. My motherboard displays error codes. After a boot with the surge warning, the error code shows "A0". After a boot with no warning, the error code shows "40". The computer also became slow to turn on, as if there was a delay on the power button. I also noticed that when I turned the computer off and plugged it some of the fan lights and the error code stayed on, something that the computer had never done before. I just assumed that a capacitor was holding charge, but turns out I was wrong. I woke up this morning to turn the computer on and it got stuck on error code "62". Error code 62 is "Installation of PCH runtime services". I did some quick research and most people said that this meant something was wrong with my PCIe port or graphics card. I unplugged my system and removed the graphics card and immediately all the lights turned off. It seemed like the graphics card was creating a circuit that it shouldn't have been. I booted without the graphics card and everything booted correctly, although I couldn't get any picture. So now I'm stuck. Do I have a bad graphics card? Or a bad PCI port? I have no way to test the graphics card. The other PCI slot on the motherboard is broken.
Thank you for reading.

My first thought is that you might have a bad gpu.

This could also be the cause of the MB power errors.

I suspect the GPU over the slot as GPUs seem to fail at a much greater rate than slots.

Although, how do you know the other PCI slot is broken?

Tried getting video output via the igp? Means taking the gtx 1060 out and use the motherboard's video output.

Could stil be the psu btw.
