Did you replace one or both DIMMS?  Maybe they are different speeds of 
memory.  Will the pc bootp with the old memory installed?  

Is the power supply AT or ATX?  If it is an AT power supply, make sure 
that the black wires are together.  I reversed them by having the black 
wires on the outside and fried the mobo.  Ok, I was a hardware newbie 
then.  Do you have another power supply to test with?  

If all else fails, take the DIMMS and power supply to National Computer 
and they can test them.  I use to do the testing all the time and right 
now I miss doing that.  I'm about to go back and ask for my old job 
back.  ~Anne
