Question Need help. PC wont turn on.

[Kirpau]

I took apart my PC recently to clean it up and install two new case fans.

After I reassembled it it was working just fine for about two days when it just shut down while I was playing Kingdome Come.
If I try turning it on now the "Power on" Led lights up aswell as the RGBs on my 1660 TI and you can hear the PSU fan spinnig. Other than that nothing else happens neiter case nor cpu fan spin.

Thanks for any tips how to fix this or what parts could be broken.

Have you reconnected all the cables in the correct places? Check you have the CPU power cable and the ATX connector seated properly. Can you post a pic of your setup?

Thanks for the Comment. I noticed more by accident then anything else that the Cable leading to the power button wasn`t properly plugged in that seemed to fix it. Feels weird to me but it works now so I wont complain.
