T5500, error lights 2 3 4 blink no boot

Hey all! Hope there's some help around... My t5500 randomly died. Would turn on for a few seconds, without booting then turn itself off. Swapped MB out, now get 234 blinking diagnostic lights (halted before transfer to BIOS control, and the fans slowly get louder.). This is with three different motherboards, two different cpus, two GPUs, two power supplies. If the BIOS isn't being transferred to, could it be corrupted? Is there a way to flash a new BIOS externally myself? This was such a great tower, and I'd rather keep it running than replace. 6x2gig RAM. First gen MB with fans on both bridges. Nvidia gtx 950 or fx1800 available. Single CPU e5530 quadcore. Terabyte Seagate 7200rpm. Any questions or input is welcome. I cannot work without my station being operational. Thanks all

Also, sorry, if I remove RAM no beeps, if I remove CPU I get the lack of hardware lights. CPU, power supply, and RAM all were verified at a tech shop, but they couldn't get it going either.

i also have similary issue  with one of my many t5500 cpus.

i have a seperate thread on it. you can search it .

if i install second cpu on riser card then it works ok .. but the fans would go full speed for which i use speedfan to control its speed once booted..

so only one cpu but all ram works in all 9 slots.

on my motherboard i saw few bent pins which i did my best to readjust them but still same issue.

i have it in repair shop. will update you if min is restored fully..
