My Dell Dimension 4400 won't light up at all this morning. It looks like power supply but is there a fuse to check anywhere first?
What does your headline "Dell Dimension 4400 Power Supply ** FREE **" mean?
Inside the pc there should be a green light. called flea light. if its not on.. then id say motherboard or power supply are bad.
take power cord off. and hold power button down for 10 ecs. then reconnect and retry. i think its abad psu.
Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.
(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.
After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say

Amazing patience: you kept trying something that didn't work 7 times, until it did! Worked like a charm for me - no $$ wasted on new motherboard, power supply, etc. Total cost: $3 CMOS battery. Thanks for posting!!

Power Supply is failing. Replace with same wattage.
There are three dummy lights that this model is equipped with. One is the obvious "everything is in order light" which is solid green. Two, a blinking green light that means your puter is in stand by. Or three, a solid amber light which means you have an electrical issue. Flea lights in this case are usually but not always bad. If the lights are on it can mean a bad hard drive, motherboard failure, ore a fuse if you are lucky. If the flea lights are off, 9 times out of 10 its a power supply which is great cause its the easiest and cheapest computer repair you will ever have. Try doing a rebuild before you buy new hardware but I'm sure its your PS!

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error
hope this will help

My dimension has bad psu. I had replaced it with dell HP-P2507F3CP psu. (Original PSU NPS-250GB B). When plug in, there is green light at the motherboard, but amber light at "on button". Fan at the PSU also not running.
Is it wrong choice of psu?
I have the same problem
the green light on the inside is on. I did what you said to do and nothing turns on. When i try turning it on, a very dim green light appears in the on button and it is not bright green as it should be. the fan doesn't turn on and there is no sign of anything powering up. does this mean i need to buy a new psu? if so, would the above mentioned psu that didn't work for that person still be a good fit for the 4400?
Same problem all the lights come on and fans come on also along with the drive but no activity on the monitor
What if the flea light does come on... then what. My daughters computer has been having a problem on and off. Sometimes it will start ... lately I can't get it to start at all. Blew dust out from inside and that seemed to help, but only temporary. Now it won't boot at all
