HP Proliant ML350 Will not even post

I have a HP Proliant ML350 G3, it has worked fine for ages then I took it down a month ago, now putting it back in and it wont boot. I get power, I get noise, but screen stays black (doesn't even flicker). I hear no beeps from posting,  just the drives and fans spinning up.

I have removed half the memory, scsi controller and still get the same results. Nothing.
If I remove all the memory after a long period I get a health red and the led's on the memory banks go orange, so i put 2 back in for testing.

I have no idea what the problem is

If when you boot the server up you hear no post beeps then there is a good chance that your motherboard and or processor has gone bad.

Try resetting the BIOS by removing the CMOS battery. You could also try disconnecting all drives and see what happens,

Gerwinjansen,

if it were a CMOS issue he would be getting video since he is not getting video this is most likely not the issue. Also if it were a CMOS issue he would have some type of POST beep code which he does not.

It could also be a bad power supply but every time I have seen this happen 9/10 times it has been processor or motherboard.

Are there any lights I should be looking at on the Motherboard to tell me if its bad? I dont really understand how it just went bad from sitting for a month. Does the fact that if I pull all the memory out I get a motherboard error mean anything?

Have you moved the server?
Do you hear the fans self-testingwhen you power up the server?
I would open it up, recheck every connection, etc., and try to boot it up again. Watch for, and remove, any dust you find.
What do the LEDs on the server look like, when you power it up and it doesn't boot?
Does(do) the power supply(ies) have a status LED? If yes, what color is it?

If you still can't boot it up I would call HP and open a support case. Some part may be malfunctioning, if not the PSU(s), maybe the bridge that connects it to (hence powering) the motherboard. Can't remember the part name, but I had a ML 350 G5 that had to have that part replaced. The behaviour, then, was pretty much the same as in your case (if I remember correctly), but the alarm LEDs on the front of the server were going wild (before even opening up the server).

Yes, I moved the server, not sure how that helps :)

As I have removed the drives, I am pretty sure the only thing I hear are the fans self-testing, but it just seems to do that over and over.

I have checked the connections, doesnt seem to be anything I can find.

My issue is it could be the Power Supply, the Power Bridge unit, the Motherboard or the CPU.

No lights on the front that show errors, nothing orange or red inside the server either.

One thing I did just notice.. when you first turn on the server, the LED at CR16 is green. After awhile it goes out, then the server seems to maybe restart in a way, the fans seem to die then come right back up, and at the same time that light comes back on.

I asked because this kind of problem is more likely to happen if you move a server and are not very careful. It is sensitive stuff.
I would call HP and see what they have to say.

SOCOM,

I would proceed with the same process as is in this article:

If the system is restarting then there is a chance that you have a bad power supply as mentioned in my previous post. You could attempt to replace this component, but I am still confident that in the end you are going to find that it is a Motherboard and Processor issue. due to the fact there is no POST or BEEP codes.
