Question PC not powering up at all, and I think it may be a dead CPU?

[GoldenTiger25]

Hi there, the situation that I am struggling with is that my PC will not turn on at all, zero functionality/response from trying to power on the PC, I replaced the motherboard (Gigabyte B450 D3SH V2), thinking that was the issue, however the problem persists and my PC simply does not want to power up at all. I have tested the PSU (Corsair CX450M) to some extent in terms of doing the paperclip test, as I do not either possess a multimeter or have any other PSU's I can do a quick switch with. I even tried to jumpstart the board with the front panel connector pins, but to no avail. I can only really think that the CPU (AMD Ryzen 3 2200g) itself has died? albeit I find it a little hard to believe, but everything has a lifespan I suppose, especially when before everything stopped powering on at all, the system crashed several times, so.. is that a correct conclusion or close enough? or is there something else I am missing, I'm really struggling with this at the moment, so any help would be most appreciated.

Welcome to the forums, newcomer!

The paperclip test is flawed, it doesn't tell how much power the PSU can effectively output.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the age of the PSU.

if you've used any donor parts to troubleshoot your build, please add them as well.

Thanks for the warm welcome!

Right here are my specs:

CPU: AMD Ryzen 3 2200G
Motherboard: Gigabyte B450 D3SH V2
Ram: Corsair Vengeance 8gb x2 (2400 MHz)
SSD/HDD: Crucial P3 1TB 3.0 NAND NVMe PCIe M.2 SSD
GPU: AMD Radeon Vega 8 (onboard) Graphics (replacing the seemingly faulty MSI Radeon RX 580 Armor 8g OC)
PSU: Corsair CX450M (3-4 years old)
Chassis: Corsair 4000D Airflow
OS: Windows 10 Pro
Monitor: Acer 22" LCD

So a bit of an update, it turns out that after doing some troubleshooting of my own, I dissembled my system to practically barebones, so just the CPU installed with the cooler, and the fans installed, as well as only a stick of RAM installed in slot 4. And to my surprise my system powered on! I then added the m.2 drive as well as connected the system to a monitor and keyboard, to try and get into the BIOS, and see if the drive registered, it did. So then I added the second stick of RAM in slot 2. Checked again to see if it would power on, it did! so with the m.2 drive, two sticks of RAM, it powers on. But then I installed the GPU...

And it turned out that it was the GPU that was the issue.. it ran fine for about three months, until the graphical glitches, and crashes I mentioned briefly in my earlier post. Everything powers on and runs seemingly with no issue, without the GPU installed, So for the meanwhile I shall unfortunately cast it aside packed safely in its original box until I perhaps figure out a way to repair it? I don't have the capabilities to test a GPU or do any work on it myself.. Anyways I'm fine with running with the onboard graphics for now. That's where I am currently at.
