I am working on a computer for my sister in law. It is an emachine T2642. It was getting some power that would pulsate but nothing would really turn on or beep. I figured out the mother board was shot (no surprise with these machines). I got a Biostar 478 socket board. I hooked everything up, re-using the same CPU and power supply and hard drive. I did get it to boot into the BIOS once right away. I did see it wasn't reading the hard drive, so figured I would try a couple of others. I also swapped out the power supply for a new one I had on hand. At that point the computer would not boot at all. The green light on the front panel will go on, but the fan will not even start. Did I do something very wrong? I find it very strange to see the green light on the front but nothing else will start up. NOt the hard drive, fan or anything. Did I do a bad thing when I left the old power supply it and turned on the new board? The PS did work on the old board, so I figured it was still good. Is the motherboard shot? The CPU? Thanks for any info you can give me.
