New PC won't start, mobo flashes once that's it
Hello r/buildapc ,
Today my new motherboard, ram and CPU all arrived.
When I installed it all it didn't start. The motherboard flashes white once and that's it. No fans starting nothing.
I have tried uninstalling several parts and starting but it's all the same. One white flash at the motherboard led and that's it.
Even when I only power the motherboard with nothing else connected it gives the same effect...
Anyone got a clue what might be the problem?
My specs are: New x570 aorus elite motherboard New ryzen 5 5600x cpu New 2x 32gb ram Old and previous working corsair rm650x psu Old and previous working AMD 480x gpu

Did you update your Motherboard BIOS, the X570 boards usually needs updating for Ryzen 5000 CPUs to work.
I haven't, I can't even get that far.
Also whenever I get rid of all cables except for the power cable to the motherboard it still does the same so I dont think that's the problem...
It did the same with my Motherboard. I had to update it with a USB with nothing else instaled/powered so it would recognise my CPU.
Do you have an older CPU to test. If not there are YouTube vids on how to flash your BIOs without a CPU/anything installed. Hopefully you'll be up and running in no time.
But when everything is detached but the mobo, the cpu shouldn't matter, should it?
