Suddenly an eMachines T2984 computer wont turn on for a client. They left it on for 3 days while on vacation, we had a few storms with lightning. They also had 2 other PCs connected to same power supply, they are still working fine. <br />
<br />
I replaced the power supply in the eMachines T2984 and have seen a green led on the motherboard turn ON.. With the original PSU nothing turns on the motherboard. However, with the new power supply unit installed, a green LED light turn is active on the motherboard but computer will still not turn on when I press the front button. <br />
What other things can I troubleshoot to determine whats wrong? Below are links to machine and green LED light on motherboard. <br />
<br />
The motherboard is an Intel Intel D845EPI/D845GVSR (You can find them on ebay for picture)<br />

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
