I have a Dell on my network that will not power up at all. Although the power button will light up, all it does is blink. PC will not POST into BIOS or anything. Am I correct in thinking it is a power supply issue...get a new power supply box/unit?

While it is possible that the power supply is having a problem, I doubt that the power supply is problem here.

The fact that you get a power light at all shows that at least the 5 volt standby power is working.

I would suspect the CPU, RAM, or a plug-in card as being bad.

If you had a recent electrical storm, the modem may have been damaged, and is locking the system bus on the motherboard.

Admittedly, the power supply is fairly easy to swap and check.
Some Dell's do use a propiatary supply though.

Chas is correct. A word of caution. Dell has used power supplies with non standard ATX connectors. Before you connect another power supply, verify that wires are in same position on connector via color codes.

First check the cable from the main board to the switch board for any short or open circuit.next u check the main board lithium stand by battery which is suppose to be 3 volts.if all that is ok, u move the stand by battery for just a MIN to reset the configurating but make sure u take out the pc backup battery to avoid damage to the circuit

This is happening when your onboard battery is out. Try replacing it. If you have a voltage meter you can check it quick.
