Since the only thing connected is the power suppy and the CPU, this is often caused by a power supply unable to provide the power to the MB. You will need to swap out the power supply and that should take care of the problem.

SOURCE: Power up

Check the capacitors on the motherboard. two or three years ago, alot of boards were affected by installation, in chinese factories, of very poor quality capacitors. To check, look at the top of the capacitors around the CPU, or feel them on the top. If they are domed, even slightly, then the capacitor is blown internally. You can replace them with better units or just replace the board.

Desktop shut down in few seconds after getting display

Good day,
The problem you describe is probably due to a faulty power supply.
The four pin connector which you unplugged supplies power to the CPU, which means you will not be able to get a display with it plugged out, as there will be no power to your CPU.
The fact that the PC does not shut down when removing the 4 pin connector strengthens the evidence that your power supply is faulty. By removing the 4 pin connector you are reducing the power required from the power supply to the point where it is not 'overloaded' enough to switch off.
You can test this by plugging in the 4 pin CPU power connector, then unplugging something else, such as the DVD writer.
Then switch on your PC and see if it still shuts down.
If it remains on then the cause of your problem is definitely the power supply.
Replace the power supply and make sure it has a wattage rating of 400 watts or more. These power supplies are relatively cheap, and should be available at your local PC store for about $15.
Best wishes,

Hello I have a ASUS P5S800-VM Motherboard with no HD on it just some RAM,graphics card,the CPU and a sound card.My problem is that whenever I switch it on it will stay on for about 15 seconds then shut...

There is no help for this, sounds like board has gone bad in one spot.
Why not use Windows to shut down the machine, or buy a surge supressor with individual switches.
Lastly, you could change out the Mboard with a new one, probable cost $40-$80 if you DIY - plenty of instructons on the WWW

Hi Tom,

Usually if a PC just suddenly shuts down after a few minutes/hours it is one of two things:

1] The CPU overheating - This is the most common problem. Usually there is no warning and it will just switch off.

2] Motherboard problem (Usually a faulty capacitor on the motherboard) If your machine has been running quite hot for some time - or it is an old motherboard - you will find that some of the capacitors on the motherboard will start to swell up. this is what they look like: You will see what looks like a "K" marking on the back of the CAP - the ones in the picture is fine but these ones : are what they look like when they are swollen. If your caps look like this - it means the motherboard overheated at some stage (or is quite old) and this will also cause a machine to suddenly turn off.

If you have a similar CPU, from a friend or something - you should try swapping that first and test - if it still happens - it could be the motherboard.

this is not a software error as the machine would not turn on after it switched off so that is not caused by a virus or a software problem.

Hope this helps
Good Luck

When I turn on my computer it runs for a couple of seconds and then stops.

Unplug everything inside the computer, except the motherboard and the front panel power on switch. Power up the computer. If the PS fan continues to run, (power supply doesn't shut down)and the CPU fan runs, then power off the unit and reinstall each device, one at a time, turn the power supply on after each device is installed (and off, before installing the next device).
You can not easily start the power supply if it is not connected to the cpu motherboard.
If the power supply shuts down with only the motherboard attached, then you will need either another power supply, to test the MB, or another MB to test the power supply.

My computer shuts down after a few minutes

2 possible issues come to mind: 1) the computer is getting hot (CPU, memory or video card), 2) the power supply can't keep up with the demand.

Try using a program that lets your track your computer's internal temperature. System Information for Windows, , is the one I use. Depending on the cause, you may need to increase the ventilation of your case (add fans - slot cooler by the video card, front, back or side panel.). If the CPU is getting hot, make sure that the CPU cooler is working and consider removing it and reapplying a new layer of thermal paste before reattaching the cooler.

If the problem is the power supply, check the specs on your devices (memory, CPU, video card) and the power supply load rating. You may need to upgrade the power supply.

I hope this helps.

(I am not a gamer but the default power supply that came with my computer didn't have enough power for the added memory and video card. I replaced that and added a back fan (spot available), a slot cooler, a drive bay fan and cut a hole to add a side panel fan.)

The motherboard the shut down when switched on

Check heatsink/fan for CPU first. If this is Ok then try a new power supply.

Asus a8v-vm se fans always run

Hi jderek4, try this. locate the toggle switch on the back of the power supply. Just find it do not flip it.
Plug the PSU's power cord into the PC. Just as you got a good connection & the PC begains to power up move the toggle switch to it's other position. The PC should power off that very second.
If the PC does not shut off than the PSU is bad. If it did shut down wait a few seconds. Press the cases power on button. The PC should start to boot up. Let it finish loading. Click the start button & choose to shut down windows. The PC should shut off.
Yes? If not than your back to (bad power supply). Swap it out.

This happens because your CPU is overheating, open your PC and blow any dust off the openings and CPU/Power supply fans, if you think one of the fans is not working... replace it.
