It turns on (fans spinning) and the mobo lights are on without the GPU and memory but the fans spin for the second and turns off and turns on again after a second and turns off and so on...

My first assumption would be that the psu is bad, failing, or not the correct wattage.
Can you list the specifications of your computer?
Do you have another power supply that you could try in the system?

I had the same problem, I replaced the video card, it came up and then started doing the same thing, I replaced the motherboard, went from a MSI 870U-G55 to an Asus M5 A97 the Asus is a much better board, the BIOS blows the MSI out of the water. But again, it started not booting up again! Did the whole thing with the Fan. It would bump for a second. The LED on the MB would light up, it ended up being the Power Supply. Which really blew me away because it's a Corsair Tx750w which they refused to place under warranty of coarse, so I replaced it with a CX500M which I really like because it's modular and I don't have to have all the cables I don't use in the system.
