SOURCE: i have a dell optiplex gx620 and it wont turn on

As you can imagine, this is not simple thing to diagnose.
First, we need to try Dell's steps to fix...
Remove non-essential peripherals…
Except for the monitor, keyboard, and mouse, remove all external peripherals including:

  • Scanner
  • Printer
  • Modem or Network cables
  • Personal Digital Assistant (PDA)
  • USB flash drive or other external Hard Drive
  • Any other external devices (e.g., USB-attached devices)
  • Remove the computer from the docking station, if you are using one

  • Remove the computer from the docking station, if you are using one
Try rebooting. If that doesn’t work, Dell states you need to do the next step.
Remove and Reseat Basic Hardware items:
  1. Power Cord
  2. Memory
  3. Hard Drive
At this point, Dells says if that fails contact them.

If my hunch is correct, you may have something on the motherboard shorting a connection or you have a blown capacitor. Get some “canned air” and blow out the computer thoroughly. Some people have reported the same symptom having dust or other debris causing the issue, so give it a good blowing out,

At the same time, inspect your motherboard thoroughly for an anomalies. If you see anything resembling the picture below, you have a serious motherboard problem which will require replacement.

SOURCE: Dell OptiPlex GX620 starts up then shuts down repeatedly

Try this: remove the DMOS battery and unplug the on/off switch plug. It's the one in the corner near the power supply. To be sure follow the cable from the front on/off switch board on back to this plug. Then plug the A/C cord in, if the system boots up fine, then replace the front panel power on/off swith board. Naturally you will not be able to power off the computer using the power switch (since we unplugged it), so you will have to just pull the plug. Hope this helps. Joe

SOURCE: my dell optiplex gx620 does not start and it shows no. 3 and 4 lights illuminated on its front . what could be the problem.?

One of your memory chips is bad.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Diagnostic Lights caution.gif CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide. To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4"on the front or back panel. The lights can be off or green. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. If the POST portion of system boot completes successfully, all four lights display solid green. If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help identify where in the process the computer halted.
note.gif NOTE: The orientation of the diagnostic lights may vary depending on the system type. The diagnostic lights can appear either vertical or horizontal.
