Dell E6400 won't boot up (most of the time)


Computer does not boot up
The problem maybe the RAM, it could be faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you.
Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

Is this a desktop or laptop? Do you see anything on your monitor screen? Have you changed any hardware in your computer lately around the time you started having problems with booting up? Have you been experiencing any problems leading up to the computer not booting up?

What's your prothe laptop didn't even boot up, the fans were whirring but not the BIOS screen came up. The CAPS lock button is blinking in intervals of two, the wireless button is orange and t


With out the mode number can't really help. Remove battery and plug in AC Charger. Push and hold Power on button for 30secs. Then try powering up again.

If unit still fails most likely to be a System/Motherboard fault. If under warranty contact HP.

Computer won't boot


OverheatingWhen the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

DELL 8400 MAKES A LOUD FAN NOISE AND WONT BOOT


There are 2 basic fans in Dell tower one for the power supply and the other for the Processor. If your computer is not booting then the Processor fan is most likely to be the culprit. What could be happening is that the Processor fan is no longer turning fast enough to cool the processor, so normal the processor when it over heats there is either protection to switch off the computer automatically or the computer won't boot. The best thing is to change the fan and make sure it is working properly but checking on the cables that they won't entangle on top of the fan to impede it's movement. You can easily damage your processor if the fan is not working properly.

Dell computer won't boot


I have the same problem with the same computer. If you get alarming beeping sounds and the fans whir, but there is no video- then the problem is most likely with the RAM. Try re-inserting the RAM sticks. Otherwise- if there are no beeping sounds and no video but the fans work or if the computer seems to be booting up but there is no video then the problem is probably with the video card. Try reconnecting the video cable and re-seating the video card. RAM slots and card slots are not very good.
Otherwise- if you get no power at all and just a blinking amber light on the front of the computer-then you have the same problem as me.I don't know.

Gateway laptop - whirring, buzzing sound


if it's a continuous whirring sound it is most likely the cooling fan. this is normal. as the computer gets older this will get noticably louder as the fan has to run faster to prevent overheating.

Constant whirring- fan?


The whirring sound could mean the computer is running pretty warm and the fan is working hard to cool it. Or your fan is flat out going bad in which case replace it. One thing you might try is to get a can of compressed air (BlowOff) and see if you can get some dust out that may make you computer run cooler and your fan run smoother.
please leave rating, thank you kindly

Louder whirring noise when turning on computer


trumpjd,
Usually on startup the fans work a little harder then slow down. On newer computers they still have noticable fan noise. Most of what ou hear while the machine is running after start up is the power supply fan. When it starts to go bad you'll hear it all the time.

Faint noise on booting.


Try this remove side cover and boot computer listen for any extra noise fan etc. also by power supply
As I think you have a bad bearing in a fan
To temp fix it
remove paper cover over center of fan and put a small and I mean small drop of light machine oil on bearing then replace paper cover.
check if this stops the noise if it does you know which fan to replace.
If it is power supply fan and if you think yourself capable remove fan and do the same to it
