Background: upgrading an old PC tonight with new MOBO, RAM, CPU.
Was able to get lights on fans etc upon first build but no POST. To try and get the system to POST I hit to "reset CMOS" button on my board, as indicated in the MOBO manual. Since then, we can't even get the fans to turn on. When we plug in the GPU, it's power socket has a tiny light, so PSU seems to be working.
Troubleshooting:
Can anyone clue me in as to what to try next? I'm pulling out my hair here, nothing I understand about CMOS should be working like this?

Troubleshooting:
- checked CPU, RAM were compatible on vendor site
- completely removed all pieces from case, cleaned it out, and reset them after the initial POST failure, no changes
- connected only CPU, RAM (1 stick), MOBO and tried to boot
- left PC unconnected for 15min, tried to boot
- used another PSU, same issue
- swapped out RAM
- ensure RAM was in the correct slot as indicated by the manual (DIM2)
