thanks
but now i have one concern
the emachines doesnt work i have 2 300 watt power supply's (the original and one purchased from comp usa) ive switched out the power supply but the new one doesnt work either any suggestions? also when i plug int he newer one i get a high pitched noise coming from the power supply. but if i unplug and replug the cord in several times i get a tiny bit of movement from the processor fan
