Desktop PC won't boot

[MistarRag]

I was trying to start up my custom desktop PC this afternoon, and nothing happened at all.

I tried checking all the cables if they were plugged in properly and all seemed fine to me.

I tried jumpstarting the motherboard as well, but without any results.

What could be the problem here?

Specs:
CPU: i7 3770, w/ Cryorig air cooler
Mobo: MSI B75MA-P45
RAM: Kingston DDR3 8GB 1600mhz (4GB x2)
GPU: MSI GTX 770 2GB
PSU: Corsair RM 650x
SSD: Kingston 128GB
SSHD: Seagate 2TB

UPDATE: Thanks for the suggestions so far, I will check on the PSU and maybe try a different one. But I will have to do that tomorrow, since I don't have a lot of time for that today

Have you tested the power supply? https://www.youtube.com/watch?v=5FWXgQSokF4

A list of your components would be helpful as well.

If power-wise it seems to be dead, likely culprit is a dead or faulty PSU (assuming there isn't a power-cut of course, or the fuse in the mains plug hasn't blown - - worth checking).

Pulled the PSU out of the PC, and discovered some tiny green bits that were loose inside it. Looked into the PSU and probably found out where they had belonged to.

The PSU did not work after trying the paperclip trick.

Still got the warranty so I should be fine. But again, thanks for all the suggestions!

Hopefully then, a new PSU will get you sorted.
