If I unplug it and plug it back in the case fan will start to run and than it stops. The fan will only run for about a second and than it stops. Also the light on the cdrom will blink one time and than it stops. Any help would be great.

do you have any light or fans running, if not check power supply, if you have heard a whirling sound lately it could be your fan dies and burnes up the supply, not hard to fix,lightning can cause this also through the network or phone, just takes one hit in the ground to lock up the diodes in the power box, most cost about 40 buck at the computer store, warning the dell named one will be high, not nec as good, Matt
Pull the power from the PC. unplug anything connected that has power. Printer, scanner, network, etc.. Open the case. (Depending on model, may be a slide catch and pull case apart like a **** shell, Or maybe 2 screws on the back of the left edge, then slide the panel back about 2 inches to release)
Remove the memory sticks, by pushing on the clips at the ends to pop the stick up.
Reseat the memory by carefully pushing them back into the slot. Make sure they go in same way, and push firmly till clips clik into place.
Plug in only the power to PC. Try to restart.
If still does same thing, it's possible the power supply module is defective, OR you need to reseat the CPU, which requires much more care and fresh thermal paste.
Before anything else, open your case and make sure all power and data cables going to motherboard, disk drives, etc are firmly seated, and remove and re-install memory sticks in the same locations. Sometimes temperature changes inside the PC can cause these connections to loosen. If that doesn't fix it, do you hear the noise of the cooling fans coming on? If you do, check your monitor for a green light. If you get a green light on the monitor and fans are powered up and running and you get nothing else it could be a hard drive issue. Try booting from CD in that case. If fans come on briefly and then shut off, or fans stay on and you have no green monitor light, this could indicate an issue with your processor or motherboard.
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
Sure hate saying this but your dell 4400 board is the trouble.
Just finished reading a bunch of post. Double check Dell's web site too. No lights lit on the back of the PC means no power & the green led you see on the board is telling you that the board has power.
Seems your not the only person with the same problem as with other 4400 owners.
One user called dell & stated the problem he had, (just like your problem), to the letter. Dell admitted there is a problem with the 4400's. mainboard. Dell does not go out & replace every board. They, like every company wait till someone has this type of problem & contacts the Mfg. Your 4400 was made back in what 2003 - 2004. If Dell still supplies your board the best they'll do is sell you a refurbished board.
I think your better off buying a new board & fitting into your Dell case. You can try to find a board that will run your current componets.
This is dell's web site link for the dell 4400.
