Dell inspiron 531 desktop does not power up?
Hello guys my Dell 531 is not working. When I switch it from the main orange light comes on followed by blue light but for a few seconds fan also turns on but after a few seconds everything goes off. I switch it on from the main may be because it was not shut down properly so even though I press the button on the tower nothing happens.I have reseated the ram but nothing happened . There is no beep. One more thing when I switch it on from the main green light on the back of the unit comes on and remains on even though every other components shut off. Any help will be appreciated. Is it the power supply unit, motherboard, cpu or CMOS battery?Thank you.
