E510 Will Not boot

What color is the power light? Is it blinking (regularly) or "flickering" (more random)?

Do the diagnostic lights (1-2-3-4 on the front) show anything?

First guess is the PSU.

What is the reading of the power button LED, solid green, blinking green, solid amber, blinking amber?

What is the sequence of the diagnostic LEDs at the front panel of the case?

Dell's E510/D5150 diagnostic guide and troubleshooter is here.

Also, check out the discussion here about the E510.

A blinking Amber LED, usually indicates a power supply or system board failure has occurred. As a power supply costs less then a motherboard, try installing a different power supply.

The D-5150/E510 does not use a Dell proprietary power supply, you can use most standard generic ATX power supplies with either a 24-pin or 20+4-pin main motherboard power connector.

This system has an open back panel, a power supply with or without the on/off switch can be used.

Make certain the power supply has two SATA power connectors.
