Dell Dimension 4600C won't turn on

When I push the power button I get nothing. I opened up the computer and I see a yellow light on the motherboard. This happened suddenly and was working fine before. Any ideas?

    How would one go about re-seating memory and daughter board?

    The computer stopped working. Nothing is seen on the Screen. The cooling fan in the powersupply is turning and the CPU fan is turning. There is a yellow light on the motherboard that is lit up and the Green power on button is lit. CD tray comes out on command. The hard drive doesn't spin up and I've tried to reseat all the boards on the MB. How can I test the powersupply?

Unplug the unit. Re-seat the Memory and Daughter-boards. Plug in and try to start.

    Unplug the computer and wait 5 minutes before performing this operation. This will allow the electricity to drain from the circuits.

    The memory sticks have levers on the sides, by pressing down lightly on these levers they should lift the memory up, you don't have to remove the memory, just press back down on the memory sticks until they lock back in.

    The daughter boards are addin cards that standup in your system, normally held down with 1 screw. Remove the screw, lift the card up and then place it back in evenly, replace the screws, not to tight.

    This will clean the contacts on those parts, and clear up any shorts.

    Plug in and try to power on your system, if it fails then most likely you need to replace the power supply. If it boots up, Great!

Dell 4700 desktop, will not boot up. Light remains


A solid Amber power LED is an indication of a motherboard problem. Remove any external connections and see if LED indications change. If no change, remove all PCI expansion cards, try again. If still no go, disconnect all drives, try again. If still no change, ensure the CPU heatsink is firmly attached (If loose you need to replace the retention module) If nothing loose and no changes from other steps, replace motherboard

I have a dell 4600c When i turn it on it powersup but no video


unplug your computer
Open the computer case up, reseat the memory by removing it and putting in one ,and starting the system,and check all power cables are connected. Do this to each memeory module that you have to test your memory.
IF that doesn't work remove , memory,hard drive cd/dvd drive,and printer etc.turn system on and if it does not beep then the motherboard is bad. The motherboad should beep to indicate that their is no memory.No beep equal no response from the motherboard. hope that helps.

When plugged in, my dell 4600c will not start up, and the light on the front of the tower stays yellow. Is this a power supply issue, a hard drive issue or a motherboard issue?


The only real way to test all is to have a 2nd pc. You can even unplug the hard drive from the motherboard just to test the MB and power supply. The bios will still load without a hard drive attached to it.

I have a dimension 4600c. installed a new power


The power supplies have extra connectors which are not used.

Try doing a system restore to an earlier date when your computer was working ok.

Restart your computer and hit F8 while it is booting. When the menu comes up, select "Last Known Configuration"

This will bring it back to a time when it was working.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Computer will not turn on at all. Dell Dimension 5100 desktop


I would unplug the power supply from the motherboard, wait a little while and then plug it back in.
Try to power everything back up and it should come up.

I am assuming you are getting a light on the motherboard that indicates power is being supplied?

Dell Dimension 4600C will not power up


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