PC not booting after changing RGB connection

[MGAdam]

Hello,
I built my system about 2 months ago. Everything worked fine.

I had it connected via the remote coming with the fans, because i thought my motherboard had no 5V ARGB connector. I realised that it had one on the bottom and wanted to change the connections that I am able to control the RGB via Software. So i removed the remote, I disconnected the fans cable from the remote and the SATA connection of the remote. I connected the fan cables to the 3-Pin connector Splitter and connected that with the motherboards 5V 3-PIN connector.

Now the motherboard lights turn on when i connect the PC to Power but it doesn't boot. I tried reconnecting the Front panel connections because i thought i might moved them, but that didn't change anything.

I connected the old remote like it was connected before but it didn't change anyting.

Does anyone have an idea what the problem could be?

i think it is possible, that you move some connections. especially the front button perhaps?

if it's possible, switch the reset- and the power-button-connectors on the board and test if it boot up with the reset switch.

otherwise check the whole cables on the board
