Sounds like a failed power supply.

When does this happen ?
At any time when you attempt to boot the computer,
or it happens ONLY after the computer has had a chance to warm up for at least a few minutes, NOT initially when it is started up after having had a chance to cool to room temp.

What is the (max total output) wattage capacity of the power supply ?
That's usually easily seen on the label on the power supply.

Which graphics card are you using - or at least, which video chipset does it have ?

You DO NOT have a graphics CARD unless it's a physical card that is plugged into a mboard slot, that can be removed.

If you DO have a graphics CARD, if your mboard has onboard video - a video adapter built into the mboard - try NOT installing the graphics card and connecting the monitor to the onboard video to see what happens.

Is air being obviously exhausted from the back of the case from the power supply ?

If you stripped it to the basics (remove any disk drives or such too) and it still won't boot up, then as above consider swapping to a known working psu.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

I thank u all for ur contributions. After going through, i relies that there are some of
the points i havn't work on so i have to go back and try them first and whatever
happens, i will come back and give u the feed back. u asked when it normally fact, it is a computer i have used for about two years. i was traveling and i need some information on my hard disk so i removed the hard disk to go
and fixed in another computer. so when i came back, i bought different one to come and fix in it. i stayed there for about five months which means i packed the PC for five months without using it. now i want to fix new hard disk and install new windows on it but anytime i press the power button, it starts alright and give me screen to press f2 to enter the bios and do my configuration. As soon as i entered the bios trying to start my configuration, then it freeze up and shut down. it doesn't
a low me to do the configuration and install the windows. as soon as it shut down and i press the power button, it starts again. and if i start it and leave it for a while without going to the bios or pressing any key too, the power stands for about 40sec to one minute and shut i brought it to a scratch by removing all the components and the expansion boards from it except the graphic card because there is no inbuilt. it is a card pug to the board so if i remove it, i cant connect
to the screen. but still, the same problem. i change the power supply to a known
good one and still same problem.but yes i can feel the air being exhausted from
the back of the case of the power supply where the fun of the power supply is
fixed.i will replace with another power supply and see what happens again and after, i will give you the feedback and also the (max total output) wattage capacity of it.
thank u all.

Did you install Windows on the replacement hard drive before you packed the computer away?
If so, was it working fine after that, before you packed it away ?

Is the "new hard disk" the same one or a third one ?

Just installing a hard drive can't cause your symptoms, unless, possibly, the hard drive has shorted, which is extremely unlikely.

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

(Dell didn't make the mboard.)

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

What to look for, mboard symptoms, example pictures:
Home page that site
- what the problem is caused by
- he says there are STILL bad capacitors on more recent mboards.

Pictures of blown capacitors, other components, power supplies, fried Athlon cpus, etc.:

You could try making sure your ram is all the way down in it's slot(s).

"the graphic card because there is no inbuilt. it is a card pug to the board so if i remove it, i cant connect to the screen."

If you mean the video card has a power socket on it that must be connected to the power supply, that indicates it requires more current (at +12v) than the slot it's installed n can deliver.

I asked these questions....

"What is the (max total output) wattage capacity of the power supply ?
That's usually easily seen on the label on the power supply.

Which graphics card are you using - or at least, which video chipset does it have ?"

....because your power supply should have at least the minimum recommended capacity for a system with the particular video chipset on the installed card.

If it has a lot less capacity that that, the video card may work anyway but the power supply will eventually be damaged from it being constantly overloaded.
If you try a different power supply, it must also have enough capacity.

If the original power supply is failing, it may have already damaged the mboard..

i thank u for ur help and i think i have to explain ur questions one after the other so that u can understand me well.
firstly, u asked for the (max total output) wattage capacity of the power supply. that is 250w. u also asked:(Did you install Windows on the replacement hard drive before you packed the computer away?)
and the answer is no.what i mean is that, the machine was working perfectly before i took only the hard disk out of it and packed it. later when i came back, i did not come with the one i took out but rather bought new one to come and install.
now as soon as i fixed the new one and powered the computer, it works for about seconds to a minute and went off. i powered it back again and it did the same thing. so i remove the hard disk and powered it and same problem. i removed every component and the cards on it but still.
so i wasn't even able to install the windows. i went back for the old hard disk. i mean the one which was in it before and installed it but same problem.
Now, u also asked about the graphic card and that is 128mb of AGP card. and here i did not say the graphic card have a power socket to be plug before it works. what i mean is that, it is a card plug onto the expansion slot of the board and since the board doesn't have an inbuilt one, if i remove it, i cannot connect to the screen.
the pictures u use to direct me through the diagnostics of the electrolytes caps too was very helpful but i did not get any physical problem on the board. so i want to ask if there is a tool which detect those diagnostics which are beyond to an eye see.
a tool which can reads on a screen to tell you that, a caps, voltage regulator, resistor,or soso and so component is defective and must be replaced.
thank u very much and i am very great full for ur help.
hope to hear from u

When you get symptoms like yours before the operating systems loads , or if there is no operating system available to be loaded, e.g. because you have not loaded one on a partition on any hard drive, then your problem must be a hardware problem.

You inspected the capacitors on your mboard, and saw nothing obvious.
You may need to look again and use good lighting and a magnifying glass or similar.
If ANY electrolytic capacitor does not have a flat top, or if you see any fluid or dried deposits from fluid on the top of or at the base of a capacitor, or any fluid streaks or dried deposits from fllud on the mboard surface that may have orginated elsewhere, you DO have one of more failed capacitors. However, sometimes there is no physical sign one or more is bad - it / they may be open (the same as if they werre not installed at all).

You've said
- the mboard has no onboard video; you're using a video card in a slot.
- the PS capacity is 250 watts.

What is the make of the power supply you're using ?

What is the make and model of the video card you're using, or at least, which video chipset does it have on it ?
Does it have a fan on it, and if so, does it spin fine when you boot the computer ?

AGP cards with older video chipsets usually have no power socket, but may have a 4 square pins connector identical to that on a floppy drive - if it has that you must connect a floppy drive molex connection from the power supply to it.

Most modern mboards will shut off (and NOT Restart automatically) if the cpu fan does not spin or if it's spinning too slowly, or if the CPU fan is connected to the wrong fan header on the mboard, a few seconds to a few minutes after you have booted, when no rpm or not enough rpm is detected from the CPU fan header.
Does the CPU fan spin okay when you boot the computer ?
Is it connected to the CPU fan header ?

If your mboard shuts off and DOES Restart automatically, whern there is no operating bsysatem, that can be caused by
- a defective mboard, e,g, that has failing or dead or missing (they blew up) electrolytic capacitors
- a defective or failing power supply - it rarely if ever causes the mboard to shut off and restart

" if there is a tool which detect those diagnostics which are beyond to an eye see.a tool which can reads on a screen to tell you that, a caps, voltage regulator, resistor,or soso and so component is defective and must be replaced.'

System Codes and Messages

You can but PCI diagnostic cards that can generate error codes, but they can only tell you what is wrong generally - they can't tell you which componrent is the problem.,

The most likely thing to be be defective or failing is the power supply, and on the mboard, the electrolytic capacitors
Other components on the mboard rarely fail.
There are some older (earlier released) AM2+ mboards that have voltage regulators for the CPU that are indequate and will fail if you install a CPU that is NOT on the supported CPU list for the mboard model that requires the circuits supply more than ~90 watts, but other than that they are one of the least likely components to fail, if if they did fail it's likely your mboard would not boot at all. For those same mboards, circuit traces on the mboard may burnt out when you use such a cpu.
Resistors don't fail unless they didn't have enough wattage capacity in the first place and in that case they would probably have failed not long after you started using the mboard.

- an AC power failure event that produces power spikes or surges or over voltage,
- a failing power supply
can damage the mboard or anything connecfed to it. The computer does not need to be running for the damage to occur - all that's required is that the PS is plugged in and receiving live AC power, but the damage is likely to be worse if it was.
Damage caused by a lightning strike on the AC power grid or anywhere close enough to the location of the computer can damaged the computer or anything connected to it - all that's required is that the PS is plugged in , whether it's receiving AC power or not.

Connecting a known good power supply may not allow your computer to run normally
- if the power supply does not have enough wattage capacity bto support both the system nand the AGP card's video chipset
- if the mboard is damaged
- if there's anything else wrong on a mboard that is not damaged that can cause the mboard to not work normally.

If the AGP card is damaged, e.g. if it has a fan and it's not spinningnor not spinning fast enough, or if it's ever been plugged in or unplugged when the PS had live AC power to it whether the computer was running at the time or not, it could cause your symptoms

If you can,
- try the AGP card with another working computer,
- or try known good AGP card with your computer,
if the PS capacity is enough to support the video chipset's system PS capacity requirements.

It's far easier to replace the mboard rather than replace components on it. Most people don't have the proper equipment to replace components in any case.
Bare minimum
- a soldering iron with a tiny chisel or pointed tip, preferably 40 to 60 watts - less or more wattage is likely to be harmful to the mboard,.
- a solder sucker, or braided wire meant for absorbiing solder
- a large needle or a dentist's pick tool with a suitable tip that solder will not adhere to to help you clear holes you can't suck the solder out of easily after trying a time or two.
Plus, you need a source for the component(s). E.g. I know from experience that local places often don't have the capacitors you need, or if they do, they're most often not the type/ quality used on mboards and may not work as well as intended .

You can often find working used mboards that were in brand name systems on the web for a reasonable price, but make sure the ad says the mboard has been tested and/or is known to be working.
