Please help - New PC won't boot at all

[Cs342]

Hi, 

I just built a new PC. I plugged everything in and connected the PSU to the wall but when I press the power button on my case (NZXT H510) the pc won't boot. No motherboard leds, no post, no fans, nothing. The case power button has a soft light around it, but aside from that there are no other lights. When I press the flash bios button at the back of the motherboard (B450 Tomahawk Max) , a red Led starts blinking. But again, the pc doesn't power up, the cooler doesn't spin, and nothing happens. I've already tried unplugging and replugging the 24 pin motherboard connector and the 8 pin cpu connector. What can I do to fix this?

It sounds like you have put your front panel connectors in wrong

also, check the actual power switch on the back of the psu...make sure it isn't in the off position.

The motherboard doesn't have any LEDs on though? So isn't it a motherboard issue?

Yes the PSU is on. The power button on my case has a white light around it and if I flip the PSU switch off then the light goes away. It's just that the pc itself doesn't turn on at all.

So do the fans spin when you press the power switch?

No. Nothing happens. I just tried removing and reinserting the front panel connectors and it still doesn't work

Then, from my experience, its something to do with the front panel. Might be worth try to jump the power switch pins with a screwdriver instead of using the case button.

Ahhhh the front panel had a breakout adapter that was attached wrongly, finally fixed it!! Thanks for your help.
