Hi all. So I've got this neat motherboard. It's an HP version of the Asus TR-DLS, included in the tc3100 server. It was working perfectly fine last time I used it, which was about 4 years ago. It has been in dry storage since and was in perfect cosmetic condition...
...except: three of the large caps near the CPU had randomly fallen out. This was due to weak solder joints as I was able to remove another one with very little force. After redoing all the joints for the related caps (competently - no shorts, etc.) and powering up the board, it ran for 2 seconds before one of the caps vented and the board shut down. I thought this was due to physical damage to the cap, so I replaced it. I didn't have an exact match (Rubycon 1200uF, 12V) so I replaced it with something close (Rubycon 1500uF, 12V) and the exact same thing happened.
Am I right in thinking that this suggests something else is damaged and too much voltage / too many amps are going through the cap in question? I can't see any physical damage, so I'm not really sure where to start. Any help would be gladly appreciated, as this is my dual Tualatin board. Many thanks.
