Hey everyone, long time lurker but this is my first post, and with a noobie problem.

I'm building a dual Xeon server right now and when it is all installed in the case everything will power up but the motherboard wont even post to bios, or anything... When I take everything out and hook it up on my desk it runs flawlessly. The only thing I could think of is if the motherboard was shorting out with the case somehow, but I've never had this issue before.
Everything is new, including the case, so I'm assuming it's the issue. The case is
Chenbro SR10568, which I can't find any issue pertaining to this.
I do have the little motherboard...nipple...riser... things in the inside of the case too.

Thanks!
 
did you install the standoffs(i think you are referring to them as little nipples. If they are not installed the mobo will not be grounded and you can fry it.
 
Look for any loose screws, wires, cables, standoffs, washers, etc.
 
Alright, I've pulled the motherboard out and drove the standoffs all in with a pliers so they should all be tight as can be. Nothing else is touching the motherboard except for the I/O shield.
Any other suggestions or should I start looking for a new case?
 
A new case can't hurt if you need this system in a hurry. There has to be either something sticking out from the bottom of the mainboard, or inside the case in the area where the mainboard is mounted. Could you perhaps take some high-res pictures so that we could take a look and give more directed suggestions?
 
Heres a few pics, just to screw my situation more I popped in an old 754 motherboard and it posted and booted up just fine. I have some Hi res pics I can post too if need be. Thanks!

It may just be me but you seem to have a few more standoffs than required.
Remove any that are not required to mount the MB, also check the back of the motherboard and see if there are any long leads sticking out from solder points, if so trim them back.
 
Yup, the 754 board would be regular ATX, while this board is EATX. Apparently it's touching a few stand-offs as I have never seen that many of them in a single case simultaneously :eek:
 
Yes, remove any extra standoffs. Make sure the backplate (if present) is not touching the mobo tray.
 
BAAADASS.... I pulled all the extra risers and hooked everything back up and it's working perfectly. I've never had a problem with having too many, but as stated above I've never used these Extended ATX boards before....
Thanks a ton
 
Note that extra stand-offs may or may not touch conductive parts at the bottom of the mainboard. If this happens the system generally simply doesn't run (due to signal and power traces being shorted to ground). It's therefore recommended to never use more stand-offs than are absolutely necessary :)

Glad to hear you got it working.
 
nice work guys! I ws kind of duprised to see his case came with aluminium standoffs, I have only seen brass ones before.
