@Julie156 -- that lamp signifies that the power-supply is receiving power.
It does not guarantee that the power-supply is sending a few different voltages to your various components.
Is your computer an "All-In-One", or are the computer-case and the monitor two separate items?
Any All-In-One is very-difficult for a computer technician to try any "part-swapping" to try as an attempt to revive it.
If a "desktop" computer does not start, the "usual suspects" are:
- a broken on/off button
- a failed power-supply
- a failed processor
- a failed motherboard
I recommend that you take your computer to a local owner/operator computer store, and first get them to experiment with a different power-supply. If that resolves the issue, purchase that power-supply. They will probably fully install it, for a small service-charge -- $20 to $30.
Otherwise, they will need to do more-extensive "trouble-shooting".
Set an upper-limit on what they will charge you for their efforts, to avoid any outrageous charge.
