We are using a Dell Optiplex GX240. My problem is that, when I try to turn my computer on then I donít get power up and there is just a steady orange light on my motherboard. I am confused that if that is the problem with the PSU or with motherboard. Can you guess that what is the problem? Please help me. I need to solve it as early as possible because I have to make a project and I need computer for that.
