Is the power button LED, Solid White, Solid Amber, Blinking Amber or is it Off?
Are there any 'Beeps', or error messages, if there are, please post the exact text of the message?
Have you made any changes to the 545 recently?

What color is the power button on the tower when you try to turn it on? And is it solid or blinking?
If you're using a power strip, surge protector or uninterruptable power supply, remove it and plug the PC directly into the wall (and maybe try a different outlet).
If the power button doesn't light up, it could be a power supply failure. Power off and disconnect the PC from the wall. If the tower has a switch on the back to change the voltage between 115 V (US) and 230 V (Europe) then move that switch back/forth a few times. Make certain it's set for the correct voltage in your location before you try to power it up again. :emotion-5:

Try removing the power cord and hold power button in for about three minutes, reconnect power cord and power system on and see if this makes a difference.
No difference, try the following, if you are comfortable working around computers:
Note: The only 100% method of testing a PSU, is to install a know working power supply.
Unplug the cord from the power supply, hold the power button in for about 15/20 seconds, open the case, unplug the 24-pin power connector from the motherboard and jump the Green wire to one of the Black wires, reconnect the power cord and power the system, if power supply's fan and the hard drive run, then the PSU should be good.
Note: Do not remove any wires from the plug, use a small piece of wire or a paper clip as a jumper.
Power supply checks out, again remove the power cord, hold the power button in for several seconds to discharge the residue power, reconnect the 24-pin connector to the motherboard.
Remove all PCI cards from the system, take out the video card [if applicable], disconnect power & data cables from all drives.
Reconnect the power cord and power system on, see if you get a different LED indication on the power button, or 'Beeps'.
No difference, remove the memory from the system and try again.
Still shows no signs of life then you are looking at a motherboard replacement & maybe a processor.

Ps. Sorry about that, Ron. LOL :emotion-1:
