Question about Compaq Pentium 4 , 1.5 GHz (244318-B21) Processor

1 Answer

Computer faliure For a while now my computer seems to suddenly shutdown but the power light remains on. If I then try to turn off the computer from the power on/off button I met with a digital screaming noise, the only way to restart the computer is by turning off the power from the main supply, i.e the wall. I am also able to download but unable to install the programs. I have reinstalled XP PRO several times, in fact it took almost 30 attempts to reinstall XP on the last count so I am reluctant to try this again. I am running a basic set up, Intel Pentium 4 Processor, 512mb. with only a quater of the memory consumed. I am starting to think that I have a damaged processor ? Is there a way of testing this or could there be a diffent underlying factor ? All Suggestions will be most welcome. Thanks for your time.

    Thanks for your message,

    I haven't been able to reply because my computer has gotten worse since I posted the last message and haven't been able to use the machine at all.

    I have cleaned the inside of the computer, and may I add, taken all the components out and cleaned them too, (as this was my first thought of rectifying the problem), but this didn't seem to work.

    I have not attempted to reset the mother board as I don't know how.

    Processor and fan malfunctions are now what I'm considering also, but as I don't know much about hardware I don't know how to run checks to enable a me to single out and identify the main cause of the shutdown.

    It is a quite an old computer, (around 7 or 8 years), but has been running fine right up to this point.

    I don't think it would be worth spending out to get a technician to look at it, so I would like to fix it myself and gain some insight into hardware issues, (it's always good to know whats underneath the bonnet).

    So thanks again for your reply and hope to hear back from you soon.

    Best regards,

Have you attempted to reset the CMOS on your motherboard? It sounds to me as though it is an overheating issue. Have you tried cleaning out your computer's dust and debris? How old is the computer? It could be a thermal paste or a fan issue as well. Just to confirm you don't get any kind of error code the computer just simply shuts down, right?

    Sorry about the long delay. What you need to do is remove the CMOS battery from your motherboard. It is a fairly straight forward procedure as long as you have the model number and find the motherboard diagnostic sheet first.

Why will my dell xps not turn on

Did it do the shutdown process or just all of sudden go black? I would try another power adapter/charger sometimes they just go bad. If you know the adapter is working and you get no lights @ all its probably something internal like the power jack or motherboard.

EMachines eMD620 suddenly shutdown and not boot anymore

When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.

Acer extensa 4620z whe i shutdown laptop it's shutdown but the screen power still remains on untill i hold the power button to off , please help me

It seems that your computer needs to have a reinstall of your original setup, because the driver that tells it to shut down is not cooperating. Hopefully you have your original dvd/cd.

I have dell c840. Suddenly only the left most light of the three lights gets orange when power is switched on and then there is no activity and screen remains blank. Bty light when plugged in also remain...


shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

lets try this ---

* turn of your computer

* Remove the battery from your computer
* Let it sit for 3-5 minutes
* Replace the battery
* Plug your computer back in (Make sure the wall outlet is working as well, seems simple, but have seen it before)
* Let it sit for about 3-5 minutes
* Boot your computer
* go to
Start -> Control Panel -> Power Options -> Power Meter
Note the Total Battery Power Remaining

* Let your computer sit for 15-30 Minutes and see if the Total Battery Power Remaining has gone up.

If so problem solved

if not you may be time for a new battery.

Will not power on

First try disconnecting ALL power to the laptop - not just at switching off at the wall but pull the plug and remove the battery as well. leave it for 30 seconds or so and put it all back and try again.

If no luck then press F8 on boot until the boot options screen appears and select 'Last Known Configuration'

If no luck then is this XP or Vista?

Sudden Shutdown

Hi, I am Sanja and will try to help you.
Try to remove battery from your motherboard, and power cable from computer case. Leave it for about minute, and then return battery, power cable and try to turn on the PC.

You should have no trouble in identifying battery, it is pretty much standard, if you have more questions please do post them

Regards, Sanja.

Computer shutting down

do you get a blue screen when it shuts off? or... does the monitor just turn off, or does the computer tower and everything turn off?

If everything turns off,(like a normal shutdown) try checking your power options in the control panel, to make sure there aren't some power saving settings that are causing it.

If its a blue screen type issue, then there may be a hardware problem that is causing the computer to shutdown to avoid further damage to the system.
