HP ProLiant ML110 G5 Server - Can't start

[Lior Narinsky]

Hello,
We have an HP ProLiant ML110 G5 Server,
Today, suddenly server's screen turned black, and when i try to power it up, i hear the fan very loud but no picture on screen.
It's not the monitor, i replaced it.
And i have disconnected everything to see if it's causing the problem, now the only thing connected to the main board is the PSU, CPU-Fan and memory (tried to replace the PSU). We have here 2 memory modules and i tried with any one of them, its the same.
Also tried to reset the BIOS.

If you have any ideas what can i do or what is the problem, PLEASE answer ASAP, this is our only Server and without it the whole office can't work.

Thank you.

Seems a CPU or mainboard failure.

Try to unseat PCI card, CPU, memory and fan and replace it.

Call HP support for onsite tech if under warranty.
