[SOLVED] New build not turning on.

So I decided to upgrade my pc. Finished assembly and tried to turn it on. As I turn on PSU switch, the motherboards LED turn on as well. Then I turn on PC. Heartbreaking split second as fans of GPU and PSU make one turn and stops. No error lights on motherboard. No fans are working and Nothing on monitor. So I try to turn it on again, but nothing. So I turn off PSU. After few seconds all LED(decorative) turns off and I try again. But the same. I can't get it work no matter what.

So my best guess is that RAM is not compatible. But no RAM warnings on motherboard and I tried that RAM switch as well. Nothing... So maybe PSU not powerful enough. I tried without GPU. Same. Tried loosen up cooler.. same result... Maybe shorting out somewhere. Next step I'll try tomorrow will be taking out from case and will try on cardboard box. Any suggestions I could try? Or if nothing will work. I'll return ram and will try different one. But I need 32 gig ram for video editing. Very frustrated. I have put together 3 PC's before without problems.


System specs.

Motherboard: ASUS PRIME Z390-A

CPU Intel I7- 9700K

GPU AMD Sapphire AMD R9 290X 4GB Tri-X OC [from old build]

PSU EVGA NEX 750B [from old build]

RAM 32GB VIPER GAMING STEEL SERIES DDR4 PSV432G320C6K

CPU cooler - COOLER MASTER HYPER 212

then some SSD's and HDD' from old build as graphic card and PSU is from my old build. Rest of it is brand new.
 
Try again with a case setup. So just one stick of RAM, your main SSD and GPU. If no result try without the GPU and use the iGPU so motherboard graphics port at the back.

Also make sure you have double checked all your cables especially the CPU power at the top left of the motherboard and PCIe for GPU...Front Panel headers as well.....Apologies as I am sure you have done this but you never know...Inetl rarely has RAM issues but try one stick at a time...

Good plan. Make sure that case fans are not connected to both motherboard and power supply.
