HP Proliant ML350 G4 will not boot

[PaddyOG]

I have a HP Proliant ML350 G4 that will not boot. It will not display anything to screen.
There are no beep codes or red lights. I have re-seated memory, processor,
array controller, disks etc and it has made no difference. When I turn it on
the fans run at full speed all the time. The disks go through there spool up
but nothing happens. If I remove the process and boot it I get the same
reaction, no error beep codes or red lights. I have tried putting in a second
graphics card to see if anything is displayed but still nothing. It’s hard fix
something when there’s no errors to go by.

get system off power,

get battery out of systemboard, pull all the memory and put 1 back,

look on the inside of the lid, on the drawing there is a system maintenance switch, switch number 6 on,put battery back,power back on and see what happens after a couple of minutes on the screen

Thank you very much, that did the trick. One of the memory
modules must be faulty. Thanks.

Good afternoon:

We have a G4p that will not boot, even after this switch 6 turned on.

What do you suggest us to do?
