Computer is not powering down.

June 27, 2008 at 01:46:53
Specs: Windows Vista, Intel Dual core, 1GB Ram

Hello Everybody

I have an AMD/ATI X800 dedicated graphics card.

My motherboard is based on Intel 945GC.

My AMD ATI graphics card is not running stably in my newly assembled computer, Vista would frequently shows "R300 crashed and recovered", Linux would just lockup.

Instead i am using my integrated GMA 950 based graphics card.
It is working well, no problems.

The problem is,
But when i set Intel integrated graphics as Primary, my computer won't power down when i shutdown from any operating systems.

Instead DVDRW, Fan all will be running, only Power and Activity Leds will be turned off :(

I done BOIS update, didn't help.

I would suspect a faulty PSU (power supply). Post the brand and model, or all the specs.

Specification.

Intel Dual Core 2.0Ghz Processor.
MSI 945GCM7 Motherboard.
Western Digital 160GB Harddisk.
AMD / ATI X800 GPU.
300 Watts power supply.

Some added information,

Because of a missing screw, a wire is used to fit my graphics card firmly.

Power button when pressed for 4 seconds, powers down the computer correctly.

One more additional information,
When my graphics card is set as Primary Graphics, i won't be able to turn on the computer through keyboard after successfully powering down through Operating System.

But i can turn on my computer through keyboard if it has been powered down by pressing power button for 4 seconds.

It sounds like you have not loaded the main chipset drivers yet.
That would account for both Windows not shutting down the mboard properly and probably at least part of your problems with the video card in a slot.

Similar to this also applies to ANY operating system you install from scratch:

Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.

The operating system knowing about the mboard's ACPI support is what determines, amongst other things, whether the operating system shuts down the system automatically properly.
The GART information in the chipset drivers is what determines whether a video card in a slot will be recognized properly by the operating system.

.....

ATX moards are always powered in some places even when the computer is not running, as long as live AC power is being supplied to the case and the power supply.
You MUST disconnect the AC power to your case / power supply whenever you change any connection inside your case or plug in or unplug ram or a card in a slot, otherwise you can easily ruin something!
This is especially important regarding AGP and PCI-E cards!
......

"I done BOIS update, didn't help."

NEVER flash your bios unless you find specific manufacturer's information information such as in release notes for the bios version, or in previous release notes for bios versions newer than your computer has since newer bios versions almost always include all previous fixes, that indicate flashing with that version will definately fix a problem you are having!

You are taking a big risk when you flash your bios - if the flash fails, and/or the flash chip physically fails while flashing (this is COMMON - these cheap flash chips can only be flashed an unpredictable small number of times), you will have a mboard that will not boot!
.....

"But when i set Intel integrated graphics as Primary, my computer won't power down when i shutdown from any operating systems."

If you mean in the bios setup, you only set that to the integrated graphics if there is no video card in a mboard slot.
When you do have a card in a slot, in the bios setup, you set Primary video or intitailze video first or similar to the card slot, or to PCI-E, or AGP, whatever applies, not onboard graphics or PCI (unless you install a PCI video card), or similar.
If you do set that wrong the the bios Setup, you still get a display in XP itself (you may NOT get a display in ME and previous) but an AGP or PCI-E card cannot work properly in it's enhanced modes in the operating system after the drivers for the card have been loaded.

If you have two ports on the card, lots of video chipsets will not work properly with a single monitor unless the monitor is plugged into the primary monitor port on the card.
That IS NOT necessarily the same as the Primary display in Window's Display - Settings.
......

If the single monitor is connected to the primary port on the card, and if the card has not been damaged, your video card should produce a display in any case until Windows starts to load - all cards, motherboards, and video chipsets have built in support for a basic VGA mode - drivers are not needed before Windows loads.

@ OtheHill

Just turning off my computer through start menu.

@ Tubesandwires

Thank you for your long explanation.

I have already installed all available drivers for my computer in Windows Vista.

My computer was powering down properly initially when i set WOL to Off.

I am not getting display if i choose Onboard graphics as my Primary Graphics Controller if my monitor is plugged in my PCI-E VGA card port.
So there is no chance for that confusion to happen,

Also the OSes are seeing only the Primary Graphics that has been configured in the BIOS.

My computer is not powering down in ANY OS,
As linux doesn't need driver installation.

Basically If the Primary Graphics Controller set to Onboard Graphics, my computer won't power down automatically :(

One more interesting find.

When i put my computer in S3 Standby mode in Vista, my computer is successfully entering the S3 Standby mode and everything is fine until i try to wake the computer up,

The computer when was in good state responded to keyboard events and woked up from standby.

But now the computer is not responding to Keyboard commands and refuses to wake from standby mode.

Eventhough i haven't overclocked my computer
When i restart the computer i get a Warning from BIOS that some over-clock related settings are failed and whether you want to restore some settings from default.

Both Yes or No didn't help me to solve the problem.

"I done BOIS update, didn't help."

I forgot to mention...........

You MUST load bios defaults, or clear the cmos, after flashing the bios if the version you used is different from what the mboarsd had on it before.

After you flash the bios, the first time you boot after that you will get a "Cmos Checksum Error...." or similar message. You will either be prompted to enter the bios Setup or you will automatically go there. Enter the bios Setup, and load Bios Defaults - save settings, reboot. You MUST do this (or Clear the CMOS by moving a jumper on the mboard) in order to make sure the bios update is fully accepted by the mboard's bios - otherwise, the contents of the Cmos part of the bios and what you see in the bios Setup may not match the bios version, and your settings in the bios Setup may not work properly.
If there is the choice to load Optimal defaults, use that - the bios should automatically use suitable settings for your situation.
Loading Defaults may work in situations where Clear Cmos does not help.

"Basically If the Primary Graphics Controller set to Onboard Graphics, my computer won't power down automatically :("

See the part in response 4 above starting

""But when i set Intel integrated graphics as Primary, my computer won't power down when i shutdown from any operating systems."

If you mean in the bios setup,.... "

Onboard = video built into the mboard chipset or built into the mboard, not video on a card in a slot.
....

"I have already installed all available drivers for my computer in Windows Vista."

See the part in response 4 starting

"Whenever you load Windows from a regular Windows CD...."

If you got the drivers from the mboard manufacturer's web site for your model, the main chipset drivers are often NOT listed!

The main chipset drivers for an Intel chipset are called the INF Update Utility.
Some chipsets also require you load the IAA as well after loading the INF update utilty, to properly support the enhanced drive controller features (if the IAA is listed on the Intel web site for XP for your chipset, you need to download it and install it as well).
...

"My computer is not powering down in ANY OS,
As linux doesn't need driver installation."

All operating systems have SOME built in support for detecting mboard chipsets properly, and it MAY detect all that is required properly, but you load the specific drivers for the mboard anyway, because the operating system can't possibly support recognizing all possible chipsets properly, especially if the chipset came out after that version of the operating system was released (in the case of XP I have seen no indication that support has changed at all in any version since XP was first released).
If you already have the correct drivers and/or information about the chipset installed, most main chipset driver installs will tell you it is not necessary to install them.
Main chipset "drivers" may have no actual drivers - for Windows operating systems they always have *.inf (information) files that tell the operating system what features it already supports the mboard has.
Check out the Intel web site to see if they have an INF update utility or similar, or instructions for where to get drivers, for Linux for the 945 chipset!
.....

"My computer was powering down properly initially when i set WOL to Off."

That's "Wake on Lan" - wake up the computer when something accesses a networking chipset onboard or on the card. Your computer won't wake up when that is enabled unless you are to something such as a corporate or institutional network
That setting has no bearing on whether the operating system shuts down the mboard properly.
....

"When i put my computer in S3 Standby mode in Vista, my computer is successfully entering the S3 Standby mode and everything is fine until i try to wake the computer up,"

Most of the time Standby will work fine with the default bios Setup settings, if your operating system has the proper ACPI support information - if you changed settings in the bios and are not sure which you changed, try loading bios defaults in Setup.
If that doesn't help, you can probably find which Standby mode your mboard and it's main chipset supports in the manual for the mboard, and/or in specs for the mboard on the manufacturer's web site.

"But now the computer is not responding to Keyboard commands ..."

If the keyboard is USB connected, there is a setting in the bios that probably must be enabled - at least it certainly must be enabled in order to get into the bios Setup.
That setting is Legacy USB, or USB keyboard, or simlilar. In older bioses that is often off by default - in newer ones that is often on by default.
If you can't get into the bios Setup with a USB keyboard, that setting is disabled - if the bios is newer, loading defaults by moving the clear cmos jumper, waiting, and moving it back may get that to work, or in any case, connecting a PS/2 connected keyboard will enable you to get into the Setup.

A side hote - using an adapter to convert a connector on the end of the keyboard's cord for use in another type of port will NOT work unless the keyboard is a "combo" one designed and wired up so that it can be used with both types of ports.

Also, ACPI support, or if you don't see that, APM or power managment support of some type must be enabled in Setup. Bios defaults usually enable that.

@ Tubesandwires

First i have to clarify what all has been working properly initially.

* I am an intermediate user.

Before the problem
* My computer was properly turning off through all OSes when i disable WOL in all OSes.

* Windows Vista was properly waking up from S1 Standby and S3 Suspend.

* I was able to wake My computer from S3 Suspend using Keyboard, but not able to turn on the computer using Keyboard, so we can rule-out the keyboard power-supply problem.

One thing i have to mention, "Before the problem" means i might be using my
Dedicated Graphics Controller.

After the problem.
* All OSes are not able to power down my computer.

* Windows Vista is not able to wake from S3 Standby.

* Installed Intel's INF installation Utility.

* I tried "Restore Optimized Defaults" option in my BIOS, didn't help.

So frankly speaking i think we can rule-out the culprit in Software side or trying to find a solution in it.

Some of the reasons i can think of that might shed some light for you in providing me a solution.

* Might this problem occur because of hardwiring of VGA card? instead of screw.

* I heard that if my motherboard is touching the ground may this problem occur?

* When we where trying to install VGA card a short-circuit occurred, would this be the reason?

I think i have to live with this problem :(

Elaborate on that statement.
