I wanted to upgrage my RAM from 128mb to 256 I have a Legend QDI advance motherboard with 3 available slots. I bought a 128mb stick and added it. The computer (Running XP) boots up and runs scandisk then freezes. I have put only new stick in and it boots fine, have tried new stick in 2nd slot and thats ok so no RAM or Faulty slot. According to an article I saw the motherboard is capable of being upgraded to over 700Mb any ideas ?
