This means that the computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).

Ensure that the processor power cable is securely connected to the system board. You have to open the cover and locate these parts. If you are not confident then I will suggest that you take assistance of a technician

I have a Dell Dimension 3000. Worked fine until we went to turn it on one day and the monitor stayed black. I'm assuming it's the video card that's the problem. I need to know what card is compatible. ...

The links in that article will allow you to determine where the failure is on you system (The power LED indications and the Diag LED indications on the back of the system)

Post back with the indications of the POWER and DIAG LEDs on the tower if you need more detailed instructions.

Dell dimension 3000 showing the following LEDS on the back a-green, b-yellow, c-yellow, d-yellow, won't boot up.

if the Dell logo does not appear at all when you start the computer, unplug its power cord, press its power button for say 10 seconds to clear any power left to it. Next, try to disconnect all external devices connected to it, then remove the power and ide/sata cables to your hard drive and/or CD/DVD drives, remove all the memory and just reconnect 1 confimed working memory to the first memor slot. Remove any other cards like video card, or network cards, then remove and reconnect the power connection from the power supply to the motherboard. Reconnect the power cable and attempt to turn it on. If the back panel light code changes, try to re-connect the devices starting from the memory, then expansion cards and the storage devices one by one. After connecting each card or device, test the system to see which device may be at fault. If nothing changes, could be your power supply or mainboard and you may need to get the replacement for them. HOpe this lead you to the right direction in getting this solved. feel free to rate how helpful this information is. Thanks

Dell Dimension Shut Down


You query suggest you have Dell Dimension 3000. Dell Dimension 3000 is a desktop PC and does not have a battery backup by itself.

I am assuming the battery backup you are referring to is a UPS (Uninterruptible Power Supply). If this is correct then by your description of the issues, the UPS may be faulty (indicated by the Red light and beeping).

Disconnect the computer's power cord from the UPS and connect it to a wall power outlet to confirm or rule out the UPS as the offending device.

If this does not help reply with more info
