PC won't shutdown but XP does

I had a similar issue a couple of years ago. I had an old 939 DFI Lanparty board that would not power down. I changed power supplies and even changed cases in desperation but nothing helped. I just gave up trying to find the cause and just got a new board. I'm not saying that is what you should do but perhaps the mainboard is no good.

Are you sure that pc is still running or it your psu fan?
some psu cool down when you turn off your pc.

My first thought was that it was just the fan. I let the PC sit overnight and it was still on in the morning. The power led light on the case was still on too.

hey, i've got even better: had the same problem. you shut down XP your screen goes black but only your casefans and (if it work also) your psu fan still turns.
i had only that problem when i was gaming and than shut down the pc imediatly. but if i was only surfing, the pc did normal. now with service pack 3 i haven't YET get the problem.

so my main question to you is: did you warm up your pc by some heavy applications?

did you game, and shut down after it within the same minute?

Emaxx - Lookup your psu manufactures web site and checkout the spec on your psu.
I use an Ultra 800w and mine has spin down technology, which took a few days to get use to. Here's mine;
(The X-Pro 800W also features "After Spin Technology" to help quiet the system and aid in prolonging the life of your components. Connectors for chassis fans are thermostatically controlled; RPM's are reduced when temperatures inside the case are low. PSU, chassis and CPU fan connectors remain spinning several minutes after the PC is powered down allowing the system to gradually cool down after use. )

Well, yesterday, I did play Doom 3 for a few hours. Another time I was editing a video but the PC barely broke a sweat (per Task Manager). The first time, it was general IE browsing.

I'm also running XP Pro with sp3 and all updates applied after that. Video drivers are up to date as well.

It's an Antel 500w PSU. It was still "running" almost 6 hours after I shut it down.

Sorry, that should've read "Antec"

6 hours?? yeah, i didn't wait until it stopped, i just pulled out the 'stekker'.

no electricity = no pc  

don't worry about it i guess, bull the plunch (how do you call the thing at the end of your electric wire?) out of you psu.

greatings

If you hold down the power button for more than 4 seconds, does the PC shutdown?

lol @ the dutch guy called vochtige XD his spelling is crap in dutch.
Dutch btw also  

moggeh !

i can't expect that i know every english word. do you know my language? i guess not

i think the most important thing is, that he has got my point!

ps i'm not dutch, i'm belgian (we don't like the dutchmen)

Its an Asus issue

as far as i know.. theres so many f*cked up things with asus boards...

If I turn off the computer... and then the powerstrip its connected to... come back later and turn everything back on... it RESETS THE BIOS.... like cmon... great preventative measures in case there was a power outtage... but I can't seem to turn it off... and its really annoying

Also sometimes i reboot... and the system is still running... but nothing is displayed... so i think somethings just up with asus settings but I have no idea how to fix it sry

i have an asus p5ld2 old model rev 1.0, i started to have this problems only this year. i have it for almost 3 years. maybe it is an asus problem. dispite, i like my pc, never had problems with it...

Yes. I assume that's a good sign?

In Windows, what should the power button do when you press it? Stand by, Shut down, Ask me what to do?

Windows is set to "shutdown".

Does the PC power down when pressing the power button if it hasn't been on for too long? If so, what are your APM settings in the BIOS?

APM setting is set to enabled as well as APCM 2.0 support enabled. The power button will shut the PC down but is inconsistent as well.

I found another thread where users had trouble with the dvd burner/rom drives attached to the master/slave connections on the IDE. My only IDE drives are my burner and rom drives. They are both configured to cable select. I know you're not supposed to have an optical drive listed as the master with an HD as a slave (can't recall the reason why). Do you think this could be the problem?

I'm thinking of ordering a SATA-based dvd dl burner. I was holding off on it but if the above is true, I'll place the order today.

The default is Suspend Mode [Auto], ACPI 2.0 [Disabled] and ACPI APIC Support [Enabled]. I assume that you enabled ACPI 2.0 before installing Windows XP Pro, but what was the reason to change the default settings? Depending on the Hal that's currently in use, you might have to reinstall the O/S if you change the settings back to their default value.

The only setting I changed was the ACPI 2.0 support to enabled. I changed it after I had the OS installed with all of my apps when the machine would not shut down automatically.

What is HAL and how do I check to see if it's currently in use.

The Hardware Abstraction Layer (HAL) can be found in C:\WINDOWS\system32. The standard one is named HAL.DLL and it's probably the one that's installed on your PC. Try disabling both ACPI 2.0 and ACPI APIC Support to see if it resolves your issue.

I disabled both ACPI 2.0 and APIC support. The PC wouldn't even reboot. I renabled it and all booted up OK.

With ACPI disabled, did it crash while booting or did it fail to reboot when in Windows?

It failed to boot. BIOS startup screens appeared and then screen went black.

Then you have to leave the default ACPI settings. What is the setting for Suspend Mode? Have you tried all possible settings?

OK, it looks like it was a defect with the JMicron IDE/SATA drivers. The driver had an issue where the PC couldn't be shutdown if an ODD (optical disk drive?) was connected. I have both of my dvd drives hooked to the IDE controller.

Upgrading the JMicron drivers finally resolved the issue? If so, that's excellent news.

So far so good. I've only had to shut down twice since installing the drivers late last night. I'll see how it goes.

I have a similar issue. When I try to shut down my PC (Windows XP SP3), it all goes well to the point when it says "Windows is shutting down", and it just stays in that screen forever. I can feel My HD turning off, but the monitor, processor fan and case fans stay on. Now, I know it isn't a XP problem (because I've reinstalled the damn OS like 4 times already from blank), but it doesn't sound like a hardware problem either, or at least I think so. I don't even believe that the procedure I'm using (pressing the shutdown button for above 4 secs) will cause my computer to eventually fail, but it's kinda annoying and I've tried pretty much everything. These are my specs:

- Asrock P43R1600Twins-WiFi
-Visiontek Radeon HD4850
-E8400 Core 2 duo 3.0 Ghz
- HD sata
- LG sata DVD Burner
- 1 kingston ddr2 RAM (2Gb)

Also, i changed my power supply (to one of 800W) but the problem keep repeating. As a curious note, I checked the registries of PowerShutDown and the other one and they were both in 0, I changet them to 1 but nothing happened.

So, any ideas? will shutting down my PC with the shutdown button will eventually cause any trouble?

A service, e.g., wi-fi, could prevent the computer from shutting down. If you boot in safe mode, does it shut down properly? If so, then try to stop a few services and then shutdown to see if it works. It's a tedious process, but it should allow you to determine what's causing the issue.

You should read as well as the Microsoft article they are referring to.

Shutting it down by holding the power button for more than 4 seconds will not harm it, but always wait for long enough to make sure that all tasks have stopped before doing it. Otherwise you could lose data.

ok, thank you for answering so fast. I tried shutting it down in safe mode, but it's has the same effect (doesn't shut down). Could it be that the MB is not recognizing the Video Card or something like that?

If it didn't recognize the video card, it would use the standard VGA drivers. That wouldn't prevent it from shutting down. On the other hand, you could test with a different video card or even an old PCI card.

What's your BIOS version? Did you install the Intel drivers for that chipset? What about other drivers?

Hi ghislaing, due to job and other stuff I put my PC aside for a few weeks, but now that I have some spare time I will try to reinstall the Intel drivers and upgrade the BIOS version, 'cuz I don't remember if I did that at some point or not. I will try to do it today or tomorrow and will inform you about the results. Thanks

I have an Asus P5WD-2 deluxe and a P6T-SE with diferent videocards, they both won't shut down after the SP3 update.
