My newly built computer powers down a few seconds after I turn it on.

Hi all,
For the first time I just build a computer and when I turn it on it shuts down immediately after a few seconds. The very first time I booted it it turned on with no issue and stayed running for a few minutes, but it did not output any display to the monitor and the red VGA light on the motherboard stayed on the whole time.
After this I decided to power it down and power it on again, but this time it started going off after a few seconds. What happens is that the motherboard DRAM red light comes on for a bit, before turning off after which the red CPU light goes on and then the machine cuts off. This is what keeps happening now.
Some of the things I tried:
- I tried to reconnect the CPU power cable as well as trying the other cable that was included in the PSU box.
- I removed the CPU and checked whether any of the pins on the motherboard were bent but could not notice any.
- I removed and reinserted the RAM. Sadly I only have one stick at the moment.
- I powered on the machine without having the CPU power cable connected, and in this case it does stay on without powering down (the red CPU light stays on in this case).
Here are my parts if it will help:
- AMD Ryzen 5 7600 3.8 GHz 6-Core Processor
- ID-COOLING SE-214-XT ARGB 68.2 CFM CPU Cooler
- HIKSEMI SSD RAYO LITE M.2 NVME 1TB Gen 4X4
- Gigabyte B850M DS3H ICE Micro ATX AM5 Motherboard
- Crucial Pro Overclocking 16 GB (1 x 16 GB) DDR5-6000 CL36 Memory
- Aerocool P500C ATX Mid Tower Case
- Super Flower Leadex III Gold UP 650 W 80+ Gold Certified Fully Modular ATX Power Supply

CPU could be overheating. Power supply could be defective and starts fine then fails under load.

VGA light is your GPU - is it seated correctly and is the cable plugged all the way in at both ends?
Which GPU do you have? Is your PSU rated high enough to cover all your components at max load?
Which slot is your RAM module plugged in to? Your motherboard will state which are the primary slots, so make sure it is in the “A1” (or equivalent) slot if you are using a single module.
Does your CPU cooler have thermal paste already applied? If not, have you applied thermal paste to your CPU?

I do not have a GPU in this machine, for now just the integrated graphics. That is also why I am sure the PSU can supply all the power I need for now.
The RAM module is in the second slot from the left, I decided to put it here since the installation manual highlights the 2nd and 4th slots but doesn't seem to provide information about a single stick and how to install it.
The cooler had thermal paste in the box and I did apply it.

Okay great.
Next question: do you have warranty on your components and are they easy to return?
It could be possible that one or more of your components is faulty (it happens).
If you can start with your CPU and try the replacement, if that fails then try the motherboard.

I purchased all of the actual components inside from Wootware and they do have warranty. It seems it will be possible to return them so I'll look into that.
I will also start with your recommendations when I do the return. Thank you for your help.

It’s certainly a good start.
I wish you the best of luck.

I had this. Would power down before post and just loop. Reseated CPU, swapped out ram and enaured all cables were connected ok. Last thing I tried was the old nvme stick. Took that out and I could get to bios. Put it back into a different m.2 slot and it posted once then the next time it failed. Ended up ordering a new nvme stick and that sorted it.

Haven't checked the drive yet, so I will try that as well. As for reseating and so it won't hurt to go over all of that carefully again. Thanks for your advice.

Likely a defective component, quite frustrating if you don't have any known good parts to swap around to figure out what is defective. The order I would try buying another set of components to test out then return later would be CPU>MOBO>RAM.

Thank you. If I do buy anything new to test I will use your order.
