there may be some status LEDs on the mainboard inside the server that 
show power on self test results.

But, its a 4-5 year old Dell, most likely its power supply has 
failed.    or the main board.  For sure its a hardware problem, as if it 
was a CentOS specific software problem, you'd see the BIOS self test, 
setup messages, then grub boot, etcetc.

standard PC server hardware trouble shooting applies...   if its on 
service contract, call your support provider.   if not, and your time is 
worth less than a replacement server, open it up, unplug everything 
extra, reseat all the remaining connectors, see if it passes 
power-on-self-test.  if not, swap PSU with an identical server, try 
again.     If it DOES pass POST w/ everything unplugged, plug back in a 
minimum amount of stuff, repeat....   etc etc etc.
