...supply? I have an older 90's model Dell Sabre computer with a new(er) motherboard and processor inside, recently someone installed an ethernet port into it, and when I turned it back on the power light just kind of blinked a little, faded away, and now the computer will not power on at all. I have replaced the power supply a couple years back, could the ethernet port have blown it, or is it fried? I have some important files on this computer not backed up that I really want to retrieve.

For the most part, your data should be recoverable by removing the hard drive and putting it in another computer.To get your computer to boot, try to remove the ethernet card and try to re-boot.Hope this helps

The ethernet port didn't do anything to it. More than likely the power supply has died. You'll still be able to retrieve everything on your pc. Just get a new power supply.

It is really hard to say if the board has anything at all to do with the power distribution problem. However, you should call another tech and have it checked again and send the bill to the first one. It is possible that a cable came unplugged, or the installed port is not seated properly, although I don't see how that would cause this problem. It is unlikely that your power supply has been compromised, but it is possible that the system has too many peripherals and needs a power supply upgrade to accommodate the new configuration. I would recommend that you do not open the system yourself unless you know what your looking for. Hope this helps.

You most likely just need a new power supply. It sounds more like the power supply is not strong enough to run with he NIC card installed. If you take out the NIC card I bet the computer will boot without a problem.
