Could be the power supply. Try unplugging the internal hardisk power, the internal cd power and anything else that is connected internally apart from the motherboard power supply. This may reduce the load enough to allow the motherboard to be powered.
As power supplies age, internal electrolytic capacitors dry out and can no longer store sufficient charge to provide power. This usually affects the higher voltage rails more, so USB devices can still get power from the 5V rail.
Try a working power supply from another computer if you can or buy a replacement to fit your case.

In my case it turned out to be a weak power supply. It would work sometimes and not others. If stone cold, it would not boot. If I unplugged 1 thing, like the hard drive or the CD Roms, it would boot. Tested the old power suppy and it seemed to pass. But once I connected a new power supply, the computer has worked fine ever since.

When I press the power switch, the green light comes on for about 2 seconds then it starts flashing red.

I'm afraid you need a new Power Supplies Unit. Just try an old trick first. Remove power cord from the back of PC. Press power button and keep it pressed for good 30 seconds. Then reconnect power cord and try to start as normal. If this don't work I'm afraid your PSU is dead. Good Luck

Red flashing lights, will not completely start up

Do you have a windows XP cd?
If so you can try booting from the cd and running recovery console.
from recovery console type chkdsk -r
This should repair any bad sectors on your drive, allowing the drive to boot

Power supply light on or flashes Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure: CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
  1. Disconnect everything from the computer, including the power cord.
  2. With the power cord disconnected , press the power button on the front of the computer for five seconds. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps. NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply
  3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America. Performing this step ensures that the voltage switch is engaged and set correctly for your country/region. Figure 4: Voltage selector switch c00517964.jpg Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
  4. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
  5. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it. NOTE: If you find the device that was causing the problem was a surge protector, resetting a breaker or fuse on the surge protector may fix the issue.
  6. Remove all attached devices except for keyboard, mouse, and monitor.
  7. Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating.
  8. Check the power switch:
    1. With the power cord disconnected, press the power button on the front of the PC. The button should release easily and not stick in the socket.
      • If the button sticks, it should be replaced or serviced.
      • If the power button does not stick and appears to be functioning, continue using these steps.
    2. With the power cord disconnected, remove the case or side panel.
    3. Follow the wires from the power button on the front of the computer to their connection on the motherboard.
    4. Look at the power switch cables connected to the motherboard. If the cable has become disconnected, connect the power switch cable connector to the connector on the motherboard. Figure 5: Power switch connector on Motherboard c00517968.jpg
    5. Replace the side panel, plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.

Pover up trouble

sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?

Red light

System does not power on and the LEDs on the front of the computer are not flashing.
System unable to power on.
Press and hold the power button for less than 4 seconds. If the hard drive LED turns green, then:
1.Check that the voltage selector is set to the appropriate voltage.
2.Remove the expansion cards one at a time until the 3.3 V_aux light on the system board turns on.
3.Replace the system board.
Press and hold the power button for less than 4 seconds. If the hard drive LED does not turn on green then:
1.Check that the unit is plugged into a working AC outlet.
2.Open hood and check that the power button harness is properly connected to the system board.
3.Check that both power supply cables are properly connected to the system board.
4.If the 3.3 V_aux light on the system board is on, then replace the power button harness.
5.If the 3.3 V_aux light on the system board is off, then replace the power supply.
6.Replace the system board.
