Computer won't turn on, GPU just blinks

[marcoxd]

My computer:
Motherboard ASUS B150M-C/BR
Gigabyte GEForce GTX 1060 windforce
Intel core i5 6600k
PSU Xigmatek Calibre 600w
Case corsair carbide spec-03
Corsair hydro cooler h55
SSD 500GB and 2TB + 160GB HDD
8GB RAM Kingston DDR4

Just assembled it and when I try to turn it on the gpu just blinks a red light for a second on the GIGABYTE led display and nothing happens.

Here is a photo of the computer (sorry for the bad cable management, this is my first computer assembled):

PS1: My psu has a voltage selector and I'm almost certain that I chose the correct one (my house has 110v and the selector is at 115v).
PS2: As stated the computer does show signal to turn on, so the case buttons are connected (I double checked it)
PS3: I have a thermaltake fan controller connected to the psu and it does not turn on either.
PS4: I tried to turn it on without the PCI-E cable connected to the GPU and it still blinks red and turn off
PS5: I made the paper clip test and the psu fan doesn't start

Try testing the board outside the case, only CPU, CPU cooler and RAM installed. Have you installed the standoffs between board and case?

I have fixed it by forcing the plugs and RAM into the motherboard and reseting the CMOS.
Thank you!
