my wife's old computer is an emachines(R) T2824
it has a 250watt power supply, a 2.53ghz celeron d 
  cpu, and 256mb of ram.
   
this is my first time trying to add new parts to a 
  pc. 
   
so far i have purchased a new oem cpu, INTEL|P4 
  3.0E 478 1M 90N ROHS % and two 512 mb pc 2100 
  stix. 
   
according to an emachines rep, this system will 
  only work with a celeron up to 3ghz and that i 
  need a new power supply to make these changes.
   
the motherboard spec's that come in a pdf file on 
  the computer say nothing about the processor being 
  a celeron, but a P4, and according to Scott 
  Mueller's Upgrading and Reparing PCs, the board is 
  suitible for both with the 478 pin configuration.
   
  this book also says that the board has automatic 
  voltage control, so i am assuming that if i plug 
  in the cpu and start it up i will not destroy 
  it--providing everything else goes right i.e. pin 
  orientation and SED.
