    Sorry but I can't seem to locate the CMOS jumper. I tried everything else and the computer is still doing the same thing. You're right, at first I hear a beep, but after it does seem like it's just the fans running. Thanks for your help.

    I have the same problem on a dell 2350. The diagnostic lights are off except for D which is yellow, and the front power light is off. The fan runs and the motherboard led is green. What would be the next steps as I have tried the ones you suggested.

  • dantehr Dec 13, 2008

    I tryed doing everything that you asked and the computer still doesn not want to boot. The fans continue to work. My brother knows a little more about computers and was able to find the CMOS and switched the pins and put them back. Still a no go. What else can I do? Will I need a new board?

  • dantehr Dec 13, 2008

    Oh yeah, I forgot to mention that I also replaced the 3v dl2032 battery with a new one and still the same problem.

When you say you hear the computer working and working do you mean that the fans are going and the lights are on?

i ask this because the fans and power lights can come on just from the power supply coming on when you push power but that doesn’t necessarily mean the cpu is functioning.

Do you hear a post system beep and the hard drive reading files also?

Or does it just sound like only the fans cam on ?

If you think that possibly only the fans are working then try this

Shut down the computer and unplug the power cable.
Check to make sure monitor cable is connected all the way
Open the case and check to see that the video card is inserted all the way into the board properly
Remove the memory (RAM) and then put it back in to make sure it is properly seated in the slots
Plug in computer and try it again and if it still does not work then try clearing CMOS
on some systems you can clear the CMOS very easily by just holding down the insert key on your keyboard while pressing power button and continue to hold it down when releasing power button until you see something on the screen but since this does not work on all computers you might have to do it manually by moving the CMOS jumper on the board
(the CMOS jumper on the motherboard is usually the one closest to the little battery that you see on the board. with the computer off move the jumper over one notch to the other pin for a second and then put it back where it was (there are usually only three pins so this is easy step)
You should now be able to boot but you will need to go into the CMOS setup and set the clock again and other settings

If you still have a blank screen then let me know and i will take you to the next diagnostic step...

Hope this info helps

    the CMOS jumper is usually the one closest to the little battery on the motherboard

    it will have three pins with a jumper on two of them just move it over to the other two pins then back

    Here is a link to diagnostic codes for your model: http://support.dell.com/support/edocs/sy...



    The D on the back of the case usually means there’s a problem with the display or the video card

    And if it’s integrated video, than maybe it’s the mobo



    But you can also try this:



    Unplug everything, cd-drive cables, hdd, pull out all expansion cards, unplug the fans than try it again

    See if anything changes

    (Break it down to i/o panel, memory, cpu and psu)

    If it’s having the same problems than try resetting the ram, if there’s two sticks than try them individually in each slot

    If that doesn't work, than unplug the front i/o panel (power button) and plug the power cable back into the psu. And it should power up automatically with the i/o panel unplugged

When i turn on my Dell Inspiron 2400 Desktop Computer why won`t it start.


Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?

I'm having problems with my compaq sr5000 desktop.


Is there any message that appears when you turn the computer on? Does anything post to the monitor during the boot process? Normally if the Video Card goes bad and the monitor works you will get a No Signal message on the Monitor. So you are so sure the monitor works, huh?

Since you went inside the computer check and make sure you pushed the Video Card (where the monitor plugs into the back of the computer) into the slot all the way.

Maybe your Power Supply is not working. When you press the power button do the fans start running and you hear the disk drive spinning? Just because you see a light at the the power button or on the motherboard does not mean the Power Supply is working correctly. I just changed one that did that.

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.You didn't by chance remove the Heat Sink and CPU while you were removing the fan did you? If you did, you probably need to apply a fresh coat of Thermal Past between the Heat Sink and CPU.

My et1831-05 will not turn on when I push power button


First make sure is properly plugged to the wall outlet, then if is plugged properly and doesn't turn on, then probably there is a problem with the power supply for your computer motherboard, nothing to do buy a new one. :-S

My friend karen press the power button, thre is no power... there blinking lights on the back of the computer near the fan power ...


Do you hear the harddrive start up? When you push the power button (or switch on the back) do the lights go out? If you hear fan running and hard drive start up then the computer itself might be on but the monitor isn't. Check the power to the monitor, the connection between monitor and computer to make sure they are all on and connected.

If you don' t hear the fan running then you have other problems. Any blinking lights would indicate something is getting power. I'm assuming the computer was working before the power button was pushed... If the monitor is actually working, you could hook up another monitor to check too then you have other problems but need more info to know what that could be.

would need to know the answer to the above questions as well as if it was working before, what was done, what changed between it working and this problem. Also what age the machine etc.

When I push the start button on my old Compaq Presario 7000 Desktop PC the power light above the button goes on and the file access light to the left of the button goes on and both stay on. I don't hear...


Try doing a power flee.. that is..

remove the power cable from the computer and all the usb devices if connected and the then press and hold the power button for 30 seconds and then try rebooting the computer.

Another possibility is that.. computer is not able to find the boot sector on the harddisk due to which its not able to turn on completely.

Another possibility is that the device boot order of the computer might have changed too in the BIOS. To resolve it easily we need to chat with each other, so reach us at hnetworking.com

sounds like your power supple has failed - you can pick any ATX powersupple from bestbuy or a retail store get a 400 watt or better ...

this is a easy way to see if the computer is shot - if a new power supple wont work - then you might need a new computer and you can return the power supply .... 40 to 50 bucks for a good power supple vs paying some 50 bucks to tell you the power is shot plus the part = 100 fix and it's easy to put in ... if you can plug up a hair dryer or a coffee pot you can change a power supply

Dell gx270 power switch


I don't think you need a new switch. The power "switch" on the front of computers today is a momentary action push button switch. Not a locking or clicking switch as older computers used to have.

Many of today's computers, including the gx270 / gx280 computers from Dell are really always on. You can see the green or yellow LEDs on the motherboards glow when they are "off" (like a sleep mode).

They are in a "sleep" mode until you push the power switch, which sends a momentary signal off to the motherboard to fully power up and turn itself "on".

I think you have something else happening here. When the system tries to power itself up, and detects a severe problem, it will try to automatically turn itself off.

The problem could be a bad motherboard, power supply, memory or processor. It could even be a failed hard disk that is drawing too much power (shorting out) from the supply.

If you had done something to the system, like move it or open it up for an upgrade, etc.. Look again at all the internal connections, and make sure there is nothing rattling around inside that might also be causing a short.

You could try removing all the PCI cards in the system, removing the power and data cable connections from all the disks (Floppy, Hard Disk, CD/DVD) and see if the bare motherboard (with CPU and memory) will boot by it self. If it does boot, then the problem was somewhere in those items and you can replace them one at a time until you find the problem, or if it all works again then it may have been a loose or bad connection.

If you have another machine available, you could try switching the power supplies and seeing if that is the problem.

Good luck!

Computer won't come on


I had the same problem, I unplugged my computer to move it before it had fully powered down. It wouldn’t start and all I got was the flashing lights.

I asked a friend who suggested I remove the power to the motherboard then reinsert it while it’s hot. Here’s what I did. Unplug the computer. Touch something metal so you’re grounded and don’t create a static shock on the motherboard. Now GENTLY pull the 16pin wire harness off the motherboard. Now plug the computer power cord back in. Then GENTLY plug the motherboard back in. With any luck the fan will start up and the computer will begin booting up. It seems to be some type of problem where the power supply doesn’t recognize the motherboard so it doesn’t do anything until it “sees it”? Probably some type of a safety to prevent motherboard burnout?
