Hi. I have a Dell Vostro 3902 that has a tendency of not booting up all the way

What happens is that when I turn it on the mouse, and keyboard lights will come on for a few seconds then shut off and the power button just stays on but the display does not come on, this usually happens when I power the pc off, sometimes it does turn on without a hitch but sometimes it's starting to frustrate me, can anyone help??

I've tried discharging the residual power by removing the plug and holding the power button but still , I even tried removing all attachments even ram cards and HDD but still

F12 at bootup. Then run Dell Diagnostics.

I already checked the service number and service expired in 2019
