Need help. Have a pc has power but no boot.

Hi, I am looking for help, my friend built a pc for me but no boot, has power, what can I do?

You ruled out the PSU. That leaves the board. If it was a CPU compatibility issue, it should at least power on and hang. Could just be a DOA board.

Sounds like power but no POST. Nothing on screen? Does the caps lock light toggle on your keyboard? Does the GPU fan ever stop spinning? Please list your specs.

The cpu and graphic card fan starts, it kicks on but nothing else happens 
Specs- gtx 1660 ti 
Ram - corsair vengeance lpx 16gb (8gb two sticks)
Seagate barracuda 2tb internal Hard drive HDD
Kingston 240gb internal SSD 
Motherboard asus prime a320m

Watch the power LED. It should flash a pattern to give you a clue about what's going on: https://www.asus.com/support/faq/1046157/

Foxtrot809

I get no flash or anything

@Foxtrot809

Is the power LED connect correctly? Make sure you have the polarities right. What CPU?

Foxtrot809

And ryzen 4 5600g

Looks like you have CPU power connected and everything. Lets make it simple. Take the board out of the case, set it up on a piece of cardboard. Connect only the 8 and 24 pin. Leave the GPU out. Just one stick of RAM. See what happens.

Now I have no power

@Foxtrot809

You short the power switch pins on and no power? You're not seeing a quarter turn of a fan or anything at all?

Foxtrot809

Neg, absolutely nothing, power supply is disconnected 

PowerSpec_MikeW

@Foxtrot809

Reconnect the CPU 4 pin. Still no power?

Foxtrot809

Nope. Everything disconnected except the 4pin and 24pin

PowerSpec_MikeW

I'd keep it on cardboard for now, rule out any short from the chassis. Do you have another PSU to test?

Foxtrot809

i got another power supply unit its a 700w one

PowerSpec_MikeW

@Foxtrot809

Try it out, on cardboard.

Foxtrot809

it is on the cardboard but no power now

PowerSpec_MikeW

@Foxtrot809

You're just shorting the board on? Did you hear anything from the PSU like a solenoid clicking type sound when you try to power it on the first time?

Foxtrot809

When I powered it on, cpu fan, and graphics card fan turned on and spinning but case fans did not spin

PowerSpec_MikeW

@Foxtrot809

Were the case fans connected to the board? Main concern is if the power LED doesn't do anything, then the board is not trying to initialize, you're not getting any POST code errors. Either bad PSU, board or you've got a really old BIOS on the board that can't properly detect the 5600G.

Foxtrot809

I do not know if they were connected at all, when I connected my keyboard it didn't light up at all, i have a 250 one and a 700 one
