HP ML350 Very loud fan - no video output

Hi,
I shut down the last of our Win2K3 servers today in order to move it to another location, it was off for 10 mins and in that time it was gently moved a short distance - it will no longer boot - i.e. no POST screen - I've seen a number of similar problems posted online and all appear to point to hardware problems but I'm hoping one of you can assist - troubleshooting steps taken so far are --

All lights are displaying as normal (i.e. green)

I've re-seated all ram (server beeps loudly if I try to boot with all DIMMS out)
I've re-seated the SCSI card
**I reseated the processor - prior to reseating the processor the fan started loudly and then ran as normal, now that I've reseated the processor the fan is continuously very loud but boots no further**

Any suggestions greatly appreciated as this is a production server - let me know if you require further information.

Thanks

Would be helpful to know what generation.. But assuming this is a G3 based on the 2k3 OS.

Just curious if you have checked to see if the battery on the CMOS and if it has a typical HP Raid controller if the battery on the plane is good?
Have you checked the processor to make sure it's not grounding out? (heat sink)
How about the power supply?
You said you moved it, have you checked the toggle switch if you went from 220 to 110?

hi,
thanks for your suggestions -

I think it's a G3 but not certain

How do I check the processor isn't grounding out?

I don't have a replacement psu - will order one for troubleshooting purposes tomorrow though

I'm under a lot of pressure to resolve this problem so any suggestions greatly appreciated

Also - any idea why would the fan suddenly go from initially being loud and then levelling out, to now being exceptionally loud?

Fans spin up to 100% at post, if the system never leaves post they will not slow down.
From what it sounds like it's honestly likely the board that is shot... But,
As a general step by step troubleshooting..
1. I would check the setting on the power supply..
2. Check the CMOS battery
3. If there is a RAID Controller, check that the Battery on it is good.
4. Check to make sure the Processors heat sink is not touching the processor (NOTE: You will need thermal paste if you remove it) (Also, if you have never removed a processor, this is not something i would recommend doing on a corp system)

5. Check the board for any blown capacitors, if they are blown, they will likely have leaked on the board.


Keep in mind removing batteries will cause the system to forget settings..
So testing them with a volt meter is a better idea..

6.. (USE CAUTION) You can pull the CMOS Battery, wait about 15min for the system to de-charge, and put it back on.. and plug back in the system, it might clear any bios based errors..

7. Check to make sure all cables are connected..
8. You mentioned you pulled ram, did you put the same back into the same place?
this should use ECC memory, so it needs to be in pairs.

9.. *** if this doesn't have a raid, and it was being replaced anyway, just get an external reader to USB and pull the data.

Good luck!

Hi,
I came back in this morning and the server started without a problem - I followed your troubleshooting tips but not sure what resolved the issue (I'm thinking over-heating but can't be certain).  Thanks for your assistance and cool head!

T38,
Do yourself a favor and don't shut it down till you pull whatever you need off of it..
As it sounds like it's on it's last leg..
