Ok well i got my older dell desktop totally cleaned down because it was in a fire that destroyed a office. It was fien after the fire because i dried it out and cleaned it but it smelled like fire. I just took it last week and totally cleaned everything and replaced some of the fans and the power supply case with a different case. I used cd drive and floppy drive of another computer and everything hooked up fine. When i went to try it, instead of the green light coming on when i hit the power button but instead the light turns orange and ofter about a minute the computer turns off. I made sure i hooked everything up correctly but i jsut dont understand this problem. i mean i already took the power supply apart again to make sure everything was hooked up correctly. I have the power supply still unhooked so if i can get any help from here it would be greatly appreciated
