Question No signal

[Yuzuke1984]

I built my daughter computer
Processor : ryzen 5 5600g
Mobo asus tuff b450 plus II supports 5000 series
Ram 16 gig ram trident

It was working fine for about 2 months no problem , but then when she tried turning it on this weekend there is no display signal i tried switch cables no luck even trying a different monitor still no luck , what i noticed is that keyboard and mouse wasnt lighting up too but the computer is on , can it be the motherboard is dead or the cpu? Tia

you'll have to troubleshoot. unplug everything external except monitor & keyboard. does it boot / get to bios? no? any beeps? if you get beeps, check the beep code. if not, unplug everything internal that isn't necessary and try again.
