Replaced Power Supply......Monitor not getting signal

Here at work, a fellow employee brought his computer to me to look at. He told me that the computer will not start.

I first looked at it and determined that the power supply was bad so I replaced it. I see the fan above the processor has started and it sounds as if the computer has started but my test monitor will not get the signal. Along with my monitor not getting the signal, it appears as if the keyboard and mouse are not getting power as well because the mouse has a light on it which comes on when it gets power. I also attached a thumb drive to the pc and it too does not get power to it.

I am thinking that the board was damaged when the power supply went out but if anyone has any suggestions as to what else I should look at I would like to hear it.


BTW the computer is a E-Machines C2280 and not too sure what the other specs are since the computer was broken when it was brought to me.

Sounds like the motherboard is grounding out. You can try reseating the board, but i have a really simple system to test if your grounding. Get a large anti static bag and remove the motheboard and place it on the bag (make sure its touching only the bag!) then hook up a monitor and power supply and turn the machine on. if it comes to life, then you have a grounding issue.
