Pc will turn on but wont boot to OS

[pfn100]

Hello,
Hope someone can help.
My dell inspiron 23 all in one model 5348. When i turn it on, the power button stays lit white but screen stays black. I have tried to connect to another monitor through hdmi out
But to no result. It does try to boot to os but all i see is a flash onscreen and it goes back to a black screen.
Could the black screen mean the integrated video is gone.
Thanks for any help.

What about the keyboard lights?
Does the caps lock work?

No keyboard lights or caplocks. Nothing working.
Thanks.

At boot do you ever see the DELL logo or nothing ever displayed to screen?

Also any history of what happened between now and last time it was healthy to where it may have been damaged in some way?

Dell logo was coming on, then next day it wouldn't, then it would. But now nothing comes on.

On this model is the RAM easy to get to to remove and reseat the RAM? Sometimes a RAM issue can cause the problem your having. If not RAM then it can be power supply or main board. All in one computers can be difficult to troubleshoot because parts aren't universal for them.

Any history of anything happening when the computer stopped working properly such as bad storm or power outage,  or computer moved from one place to another anything like that which would suggest that there is physical damage to it in any way?
