Hi When I try shut down the pc Windows XP will close leaving the power supply, cpu,fans, usb still running To shut down the pC I have to turn off the power switch at the rear Please help

It may be worth trying to re apply the thermal paste to the processor, make sure you remove power from the machine before you open it up. The CPU may have failed, but they don't fail very often, so try the paste first, it will only cost a few GBP for a couple of applications.

the cpu could be over heating make sure its secure if you like get some thermal paste from your local pc world put a little on the top of the cpu under the cpu fan and replace fan securely might work be carefull....bonnell

Hi,

There are two harware you should check,


First the memory, it might be malfunctioning, if you have an extra memry card, try to swap it just to test the syatem.


Second will be the power supply unit or PSU, that is already overheating and shutting itself down, thus its not powering the your hard disk. try to replace it if you have an extra PSU.


Those are the most probable problem you have, PSU is the main problem in any desktop that was always been overlooked!


Hope that helps you out!


Thanks for using Fixya!

looks like old xp machine. power supply could be flaky,bad caps on the board,dust build up on the cpu fan or graphics card causing it to over heat and shut down

Hi,

This usually happens if Windows is having trouble closing a program. The easiest way to avoid the problem is to close all programs before you close Windows.

If that does not help, you need to track down which program is causing the problem.

If you are running Windows 95, remove all shortcuts from your StartUp folder.

If you are working with 98/ME/XP, uncheck all the programs listed in StartUp in the System Configuration Utility (you get to the utility by opening Start/Run and typing "msconfig" without the quotes in the Run box and then clicking on OK).

Shut down the PC. Reboot. Shut down again.

Then add one program back, shut down, reboot and shut down again.

If Windows shuts down as it should, add a program back to StartUp and repeat the shutdown, reboot, shutdown routine. Do that until you have pinpointed the errant program and reinstall it. If you are running a screen saver, consider it also to be a prime suspect.

Your Advanced Power Management, or APM, utility has decided to take leave of its senses.

Disable it, both in your BIOS file and in Windows.

That little sound riff that accompanies the shutdown is hitting a sour note.

Go to Control Panel and click on the Sounds icon to open the Property dialog box.

Scroll down in the Events box until you see Exit Windows. Change the sound settings to None.

Your TEMP folders are bulging at the seams.

If the C:\Windows\TEMP folder gets overloaded, all sorts of bizarre events can ensue. Clean it out. While you are at it, clean out your Temporary Internet Files folder as well.

Updating XP with the latest Service Pack may also cure the shutdown failure.

However, it is also possible that Advanced Power Management, or APM, is getting in the way of the shutdown routine.

APM may not be enabled in your XP configurations, but it may be turned on in your BIOS, a memory-resident program that controls how your PC sets itself up.

Microsoft recommends that you go to the Control Panel, click on “Performance and Maintenance,” and choose Power Options.

Click on the APM tab and click on Enable Advanced Power Management Support.

Personally, I don’t like automatic power management on desktops because it can cause all sorts of bizarre behavior. I would leave Advanced Power Management disabled in Windows and turn it off in the BIOS.

Consult your PCs manual to determine how to enter BIOS’ Setup file. Sometimes, as the PC boots, you can see a message on the screen that tells you which key to press to enter Setup. Press it before the screen welcoming you to Windows appears.

Once in Setup, look through the various sections until you find the option for controlling power management. Choose to turn it off.

For guidance on other XP shutdown problems, consult article 308029 in the Microsoft Knowledge Base. Use the article number as a search term at the support site below. Good information is also available at the aumha.org site.





Regards.

what os are you running? if xp try booting to repair console and run "fixboot" and or "fixmbr".

I don't know if you've tried this yet,but here it is just in case.



Click Start, and then click Control Panel > Performance and Maintenance>Power Options>In the Power Options Properties dialog box, on the Power Schemes tab, click the Power schemes drop-down list and select the power scheme that most closely matches how you use your computer.
adjust the System standby and System hibernates settings if you are not happy with the default selection. On the Advanced tab, you can adjust the default behavior of the power buttons on your computer. Click Apply>OK

Which fan are you referring to? As far as I know the fan in the power supply runs at the same speed at all times. So if that is the fan you are hearing it may indicate that the power supply is failing. The power supply may be over heating and shutting down. I would try a different power supply if you can get your hands on one.

Hi rebecca_fran,
Well the system is shutting down for a reason but before you run off & buy a new CPU fan I want you to try something.
Unplug the power cord from the PC. Open your case & ground your self by simply touching any bare metal. (The bottom of the case will do).
Please remove the memory currently in your system. If you have never done this before please check within the manual for your eMachine. (There should be a section on how to install memory).
You can also click on this uTube link, it’s a bit long but you can skip through the video.

If you have some canned air blow out the memory slots.
(Do not place your fingers on the memory contacts at any time).
Re-seat the memory, firmly but gently. Leave the case opened & plug in the power cord. Turn on the PC. See if the fan runs & the system doe’s not shut down. If it still does replace the CPU fan.

Your PC uses an AMD Athlon 64 X2 4400+ / 2.3 GHz CPU.
Here is a replacement AMD CPU fan & assembly.

The CPU will come with thermal tap on its underside. (No need to buy thermal grease).
(Make sure you remove the old thermal grease from the top of the CPU). Use a clean rag with a little alcohol on it. (Not dripping). Allow time for drying. Do not scratch the CPU surface.

Good luck rebecca_fran!

1. if possible check and see how dusty the system is inside.. used compressed air cans to dust it off.. don't touch any components... watch esd so ground yourself while you're at it
then test
2. you're power supply may be dying: ground yourself to the same ground as the computer (watch for esd) and replace the powersupply.
then test.
the keyboard or controller may be damaged, check for resource conflicts in your bios related with keyboard (make sure no other items are using the same irq's.. check plugs, test with other key board.. replaced motherboard.
random shut down could also mean that the cpu is overheating.. make sure the cpu fan is undusted and working.
