My pc has been unplugged for 2 weeks.. now when i plug in the pc ..the blue light on the front panel doesn't come on at all, but a green light on the back of the pc starts flashing..also when i plug the power cord in the wall outlet it makes a little spark.I'm not sure if it's the power supply or the motherboard..
The green light is most likely your lan card/port. If the cord/outlet are sparking when you plug it in, I would say try plugging something else into that socket, if you get the same spark, I'd call an electrician. Also try plugging the pc into a different outlet. As far as the computer, if its not the outlet then it is the power supply, your motherboard may be fried in the process but if this isn't an issue with that outlet, then you should take it in to a shop.

I've tested the power supply unit (PSU) with a multimeter..as long as the P1 connector isn't plugged into the motherboard a 12V current is running through P2, P3, P4,...and the green led light on the (PSU) is solid green. When I plug the P1 connector into the motherboard the current running through P2, P3, P4,..is 0V and the green led light on the (PSU) is flashing. I've come to the conclusion that it's the motherboard... I hope I'm right.. wish me luck...anymore suggestions..?
