Hello! Recently I bought a new CPU and new Motherboard (i5-4670k, ASUS z87-PRO) I migrated my parts to my new motherboard. Im working with checkpoints. First I installed the CPU(with the cooler), RAM, PSU, 1 SSD, 2HHD. I started it up and it booted to bios with no problems. Later on, I put the GPU(GTX 670 Zotac amp) and when I press the power switch the fans spin for a second and then everything stops. I don't get an error code from the motherboard(Z87-Pro has a little 2 eight digits LED that shows the error code). Then I replaced my GPu with some old one(GT 210) and it worked. I updated bios to its most recent version but nothings changed.
I need help guys. If anyone knows why and what is happening please respond to this thread.
I can take pics of the GPU if it will help.
Thank you in advance!
