[SOLVED] Disassembled my pc and can not figure out why my cpu will not boot.

Alright, first of all, here is my full part list: https://pcpartpicker.com/user/cameron13x/saved/QXbQZL
So, I had my cousin over today (who has recently completed his first build, and is pretty knowledgeable,) and we disassembled my pc, trying to figure out the culprit(s). We think the issue may be the cpu socket, the cpu, or the monitor (as it will not post anything.) The cpu indicator is the only one that turns on, so I know that the ram, ssd, and most likely gpu are fine. All of the lights turn on, including the case fans, cooler, and gpu lights. Some potential concerns I have are:
1. There was a very small amount of thermal paste in my cpu socket, not even covering any pins.
2. There was a smidgen of thermal paste on my motherboard.
3. One of the motherboard standoffs could not go in, as the pre-installed piece attached to the case would not allow it to be screwed in.
4. I put my cpu and cooler in, and the cpu will not work.
5. I connected the HDMI from the monitor to the gpu, then tried the motherboard, and nothing would post.
6. My psu is only 650 watts, and the recommended is 750 watts.
7. The cpu is fused to the heatsink.
8. I have already (successfully) RMA'd one cpu.
Any advice will help, and if anyone successfully undermines the issue, I will gladly give some coins, thank you. :)
There will be images of some of the issues on my profile.
 
Solution
From the manufacturer's website (http://www.arcticsilver.com/as5.htm):

Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

I would focus on the four components: CPU, motherboard, memory, power supply. If possible, test each component in a working system to see if it works. For example, transplant the CPU and memory into a working system with a compatible motherboard. If it works in the other system, then...
650w is enough and especially that quality unit.

What graphics card do you have? Couldn't see it listed at your pcpart list. Could you also clarify monitor as the aoc model there lists as only having vga and dvi, no hdmi.

2700x doesn't have an igpu so the motherboard video ports wont be working unless you had a G model Ryzen cpu ie 2400g (g for graphics).

Thermal paste isnt usually conductive so i think that should be fine. Long as there are none on the pin tips.

Check over things in this guide

If you are using the Arctic Silver paste, and got some of it INTO the actual CPU socket...I'm pretty sure that is a conductive paste.

And after reading through the rest, it sounds like you may have multiple issues, not sure where to start. You might try some basic pc building tutorials. There's one here on Tom's somewhere, can't seem to locate it.

This is very helpful, except for one thing, I don’t have a spare motherboard for testing 🙁
