The best way forward in these instances is to strip the machine down to basics. Remove all boards and extra drives and just leave the motherboard with one graphics card. Then try rebooting again. If it boots, then start replacing the peripherals and cards one at at time. Eventually you will work out what the problem is!

If it still does not boot, try swapping the memory cards ... or if you only have one then try reseating it. SIMMS/DIMMS can work loose with the vibrations of hard drives/fans etc.

Good luck!

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the onboard)

If you hear any beeps these can indictate where the fault is.
either of these sites below will help you further with that

Beep codes P
c

More beep codes

Power up the pc and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.

Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

During a recent thunderstorm, the power fluctuated and my dell dimension 3000 turned off. There was popping sound and now I cannot power on the computer. When I take off the side panel, I can see a green...


The popping sound is most likely your power supply or something on your system-board like a capacitor.
If the problem is only the power supply:
If you want to see if you can salvage it try just replacing the power supply. The part is around forty dollars. You can google "Dell Dimension 3000 250w power supply" to find a deal on a power supply.Here is a link on how to replace the power supply in that computer.

No power -- Dell Dimension 3000


There's a few things you can check, check your wall socket, make sure it is giving out good consisten electricity, not flickery. Make sure you have a surge protected plug box or ext. cord. You just can't buy any pwr supply because Dell has an extra pwr supply lead that goes to the mobo on many models. Standard supplies have one bundle that has a double row of wires on the connector that goes to the motherboard, and all the rest go to hard drive;CDrom drive;floppy;maybe a procesor fan. Check your connections, make sure they are proper, if that doesn't work, it could be something damaged on your motherboard and you might have to change it. Depending on how your power supply failed, it can actually do some damage on the other parts but check everything first before considering that.

Power supply or motherboard dell 4600


Ok, you stated that the power supply cooling fan was running at this time. unfortunately, this is not the power supply unit that has failed. the mother board has actually failed in this case. If the power unit was damaged, the cooling fan would not spin. You will need tp replace the mother board in this case. it has failed.

This is not a novice situation. we recommend a service tech for this type of repair. if it was a power supply issue, it would have been quite easy to replace but, this is not the issue here. it the mother board.

Yellow light on dell dimension 2400 and it won't work


HI, this is signaling an issue that is concerning the power unit(power supply). this can also be an issue with the mother board as well. you can confirm the actual issue by, inspecting the cooling fan that is on the power unit. if the power unit fan is not running when you push the power button to power up the PC, replace the power supply. if the fan is running, replace the mother board.

Dell dimension 3000 desk top, does not turn on ?


It's one of two problems: bad power supply, or bad motherboard. If you are electro-mech inclined, remove the power supply. Take it to your local computer repair shop, and ask for one just like that one.
Reinstall, power up should (most of the time) fix this problem. If still no power, you need a new mb. Return to the shop, ask them to replace mb. This repair should be right around $250.0 - tops. Any more than that - replace computer.
Hope this helps. Either way, if you wouldn't mind taking the time to rate my response, it would be much appreciated!
Thanx and good luck.

Dell Dimension 4600C will not power up


Sounds like the power supply is faulting. If not it is your mother board that has failed.

Dimension 8200 will not turn on


Try a new power button. Also does the machine power light turn on at the front of the machine? if so check that the CPU is seated correctly as if it has come out of position then the machine doesn't boot. I would like to think power switch though.

Thanks J
