Solved PC shuts down within a few seconds

November 28, 2012 at 22:47:54
Specs: N/A, Pentium / 8 GB DDR3
I just built this PC for the first time. All components were installed according to main board instructions. But about 5 seconds after I turn on the switch, the power is shut down. All the components are brand new. It shuts down with or without cpu installed. I see the HDD, DVD , Keyboard and power on light switch turn on for a few seconds. So does the fan on the front panel and PS fan run for a few seconds but then every thing completely shuts down. I have a 650 W PS, 500 WD HDD and multi task DVD/ CD installed on to an ATX mother board made by MSI.

Sometimes the power is turned on after a few seconds that I press the start button. Looks like there is a delay somewhere.

Can anyone help me please?. Thanks.

I bought another mother board of the same brand but in Micro ATX form factor, removed all the components from the old one, connected them to the new one. It started up right away and I was able to install Window 7 in to HDD.

Therefore I will send the older mother board to MSI for them to fix or replace it mean while. It must a faulty mother board.

Thanks everyone for your help.

List complete system specs with details and don't forget PSU specs(brand name & the amps from these rails +3.3v, +5v & +12v).
To start the system without a CPU is pointless, CPU must be installed and thermal paste(use small middle dot method) must be applied correct then the fan must fit well.
After CPU, Ram & v-card(use the onboard video if the board have one) already installed correct benchtest it. Benchtest should be performed outside of the system case or tower.

Hi Kuwese,

Here are the Specs you asked:

SPU: Antec 25 650 Watt
+12V Rail: 24 pin Main Connector, 2 X 8 pin ATX 12V, 8 pin PCI-E connecto " Yellow, w 8 pin PCI-E Connector (yellow/black), 5 X Molex, 7X SATA, 1 Floppy.

CPU G630 Intel Pentium 2.70 GHZ, Sockett 1155

2 X4 Kingstone DDR3 Duel Channel memory.

1 500 Gigabyte WD HDD SATA 6GB,

1 SATA DVD/ CD drive.

You can access the MSI Web site and look at the image of the Mainboard by going
to MSI.com, click on the product, Click on the mainboard, click on the Socket 1155 and select the ZH77A-G43.

Even thought the MSI CPU support says that it will support the above mentions CPU with this Mother board, but i think the problem is the CPU. CPU is nicely fitted in its socket and fan is over it.

Any help is very much appreciated.

If it shut down without the CPU being installed, then how can it be a CPU problem?

I do not know. I just talked to MSI Support. He told me this mother board supports the CPU I purchased. I am gussing it could be short somewhere on the board or it could be extra +12v "8pin CPU power supply on the mother board.

I was asked to remove the mother board and lay it on a cardboard and test it to see if it will not shut down.

Thanks.

The thermal paste and heatsink must be installed correct or otherwise the CPU will overheat and the system will shutdown immediately.

Take your time and read how to benchtest.

I had same problem. I reseated (took out and put back in) the processor and the RAM. Then all worked fine.

Try this before taking apart your whole PC.

I did the bench test tonight. I removed the Main board from the case, removed and reseated the CPU and its fan, I did exactly what that link shows. Yet it did the same thing when it was in the case . It turned on for few seconds and shut down. I noticed the CPU and PSU fan span, keyboard, front panel and HDD lit for few seconds and shut down.

Also I noticed that neither the main board's VGA port nor the graphic card on the PIC-E recognized the monitor connected.

The power in to the DVD Drive is not even long enough for me to insert the Window 7 CD.

I even used only 4 pins instead of 8 pins for extra CPU power supply according the video above.

It has to be something wrong with the power. it is not like one component works and the other shuts down. They all shut down.

Any help is appreciated.
Thanks.

When bench testing you should NOT have any case to motherboard wiring connected.

All that is needed are the following: Motherboard with CPU/heat sink/fan, 1 stick of memory, power supply 24 pin and 8 pin connections, keyboard and monitor.

NO other cards, drives, external hardware, etc.

Your power supply is modular with 4 - +12V rails. It is important that you use the correct leads as described in the manual for the supply. I am not a fan of that type of power supply.

Currently your CPU will be providing video. If you decide to install a high end graphics card your power supply may not be able to properly support it.

Going back to the bench test. You start the system by momentarily shorting out the 2 power pins on the motherboard. The system should POST and you should see a message that there is no boot device, or something similar. If you get that far then you can install into the case and repeat with ONLY the same hardware. Be sure you have metal standoffs under every screw hole and ONLY under those screw holes.

Then you can start adding in stuff.

Be sure to have the heat sink fan connected to the header marked CPU fan and also the 8 pin auxiliary CPU power connector is connected.

When I did the bench test, I started just like the video showed. I disconnected everything from the main board, removed the main board from its case, laid it on its box. Then, I removed one of the memory sticks, connected the monitor to the on- board video port, connected the keyboard, removed and reseated the CPU. I also reconnected the front panel start-button cables to the pins on the main board. I re-connected the 24 pin and 8 pin power supply cables to the mother board, and made sure the CPU fan is connected to CPU fan power supply on the main board- the 4 pin close to the CPU fan". I Plugged in the power cable to the wall, turned on the switch on back of the PSU and pushed the start button on the front panel.

CPU and front panel fan span for a few seconds, and front panel start button indicator light lit for a few seconds and shut down. Nothing happened to monitor, I did not see any thing on the screen.

There must be something wrong either with the CPU or its socket."

Also this is an ATX Form Factor mother board. The case came with 9 metal standoffs, I matched them with holes on the case.

May be this board only supports socket 1155 with i3, i5, or i7 CPUs even though under support in MSI website it indicates that this mother board supports all Pentium CPUs also.

I do not know what else to do.
Thanks.

Did you apply thermal compound to the CPU before installing the heat sink?

Page 1-30 of your motherboard manual shows how to clear the CMOS. I suggest you do that. Be sure the power cord is unplugged when performing this operation.

Also, push the power start button a few times while the power is unplugged before clearing the CMOS.

You can short the pins momentarily with a flat blade screw driver if you don't have a jumper.

Is there any indication of the BIOS version flashed to the BIOS? The CPU you have requires version 7758 v10. I think that is the default version because nothing older than that is listed on the MSI site.

As I stated above, your power supply is not a good one to use with your setup. The 12V rails run from 22A to 25A. This should be enough to run

I just spoke with a MSI tech support. He said the CPU I have on the board will work with the BIOS version on the mother board. Therefor there is no need to Flash BIOS. The fan that was included with the CPU had some Thermal Paste on a tape when I installed it. But becasue I removed and reset the CPU Several times, I need to buy some and apply on the CPU. 5 seconds will not overheat the CPU.

I think I'm just going to send the Mainboard back to MSI and have them to test it for any problem. Either they tell me there is nothing wrong with it or they will replace it for me.

There is current in all components on the mother board when PSU is on. Like I mentioned it before, it shuts down either with or without CPU connected on the motherboard.

Any help is appreciatted.

5 seconds is plenty of time to kill a CPU if thermal protection isn't there.

You MUST apply the thermal paste correctly. It should NOT be re-used. If you remove the heatsink, the old paste has to be completely removed from the top of the CPU & bottom of the heatsink, then fresh paste re-applied. Once again - it MUST be done correctly! The Pentium dual core uses the horizontal line method:

Believe me the problem is not if I used thermal paste or not. I put some every time I remove and re-seat the CPU. The problem as see it is that when I turn on the power, I see all the components attached to mother board work for few seconds and all shut down at the same time. I don't even hear a beep. I connected the ATX 24 -pin power cable connector and the 8-pin 12V power connector for the CPU on the mother board.

Here is PSU specifications:

Model EA-650 Green

AC input 100V-240V~/9A-4.5A; 47Hz-63 Hz

Dc Output +5V +3.3V +12V 1 + 12v 2 -12V +5vSB

24A 24A 38A 38A 0.5A

+3.3V, +5V max.load 140W
+12V1, 12V2 max.load 650W

Total continuous output 650W

Thermal paste MUST be applied correctly. If you didn't clean off the old stuff and/or apply too much, the CPU can overheat in 5 seconds.

You haven't talked about how you are securing the heat sink. If ALL the fasteners are not secure the CPU will overheat.

You may not understand how critical cooling is to a modern CPU. There is a lot of Wattage flowing through a tiny piece of silicon.

What you describe is typical of improper installation of the heat sink.

Up above I posted what I thought were spec for your power supply. Had you provided a model number then I would not have stated yours has 4 +12V rails. When visiting the Antec site that is what I found.

Are you positive you have the CPU fan connected to the header marked CPU fan?

Do you have ANY case wiring connected to the motherboard other than the 2 wires from the power switch to the pins marked power? If you do, then remove them

Hi,

I know that it is critical to clean the thermal paste and to add sone fresh one on the CPU every time I remove it. Also the CPU fan and the heat sink came as one piece toghether. And I am positive that fan is securly connected to cpu above mobo. Also CPU wire is attached to the CPU fan connector on the mobo.

The problem is that even with every thing disconnected, except the front panel's, power switch, speaker cable, and USB cable to the mobo, it shuts down.

When checking the list of compatible and tested PSU under test/ report in MSI website, I noticed that my PSU was not listed. So I'm guessing this could be problem.

My PSU brand name is Antec 25 EA-650 Green. That Green word may be problem, trying to save energy immediately therefore shuts down.

What do you guys think?.
Is there any way that I can attach images to my emails in this website?.

Thanks.
