    Win2K shuts down and restarts

    I've got Win2K Pro Version 5.0.2195 Service Pack 3 Build 2195 running on a Gateway G6-233m (Pentium 2) connected to a small home network (workgroup of 4 PCs - 2 Win98SE, 1 running XP Home, and the Win2K machine). I've got over 20 years experience as a programmer and have used (and confused) Windows machines for since '95, however, I'm relatively new to Windows 2000.
    I'm running into several problems since I installed Win2K on this machine (from a minimal Win98SE install). The most annoying is a shutdown issue where windows closes completely, the machine appears to power down (drives stop, monitor goes to sleep, lights off ... everything silent), then the machine reboots and I have to hit the power button to turn it off.
    I tried the Microsoft Knowledge Base Article - 315409: Troubleshoot Shutdown Problems in Windows 2000 to no avail. Anybody got some other suggestions? I prefer to fix a problem rather than bandaid it.
    Thanks - Jamie

    Re: Win2K shuts down and restarts

    Does this 'shutdown behaviour' happen when *you* shutdown? - or does the pc shutdown on its own?
    Does the reboot occur immediately after shutting down?

    A few things to check:
    Does your NIC support a wake-up call when you have shutdown?
    Check what hibernate settings you may have - personally I would avoid any.

    Re: Win2K shuts down and restarts

    Yes, this happens when I shut the computer down using Start | Shut down... | Shut down (It doesn't occur spontaneously). There is always a one to two second period after "power off" before the machine begins POST procedure, however, I consider that to be immediate since it fits with the PCs normal boot up speed.
    There is nothing to indicate that this NIC supports "wake on LAN". It was one that was supplied by my cable company when they set up my high-speed internet connection two years ago. There's very little documentation with it and the cable company's tech support does not believe that they supplied any home users with NIC cards that support auto-wake functions. However, they've made mistakes before (as I can attest), so it's possible that I have such a NIC, but I just don't know.
    I don't like hibernation set on my computers (they cause too many other issues for me), therefore, I've confirmed that all such settings are turned off. Do you have any other suggestions. This has only been a problem since I removed Win9x and installed 2000.
    Thanks, Jamie

    Re: Win2K shuts down and restarts

    1] Try disconnecting your LAN connection right after the saving your settings window disappears - that may clear up any doubt about the wake-up call.
    2] What happens if you start in Safe Mode and shut down?
    3] Anything in the event log?
    4] Are you running any logon/logoff scripts?
    5] Do you have a UPS?
    6] As a matter of interest, what do you see at the Reg key mentioned here at JSI?

    Re: Win2K shuts down and restarts

    1] I disconnected the PC from the LAN in the manner you suggested -- No change -- it still rebooted.
    2] In Safe Mode, it went through all the shut down processes then gave the message "It is now safe to turn off your computer" and waits for the power button to be pressed.
    3] The error log contained several error messages within one of two categories:
    DCOM - Server not registered with DCOM
    Service Control Manager - No attempts to start Telephony Service since last logged on.
    4] I haven't set up any logon or logoff scripts and no one else in my household knows how.
    5] There's no UPS connected to this PC.
    6] The Registry setting contains a value of 2 (hexadecimal).

    Re: Win2K shuts down and restarts

    Have you checked for a BIOS update?

    Re: Win2K shuts down and restarts

    Yep ... no such luck. Gateway stopped supporting the machine almost on the day they built it (six years ago). <img src=/S/bwaaah.gif border=0 alt=bwaaah width=123 height=15>

    Re: Win2K shuts down and restarts

    Have you checked the BIOS itself? There is sometimes a BIOS setting that asks what to do on a Power Failure. The motherboard may be taking the Windows shutdown as a power failure, and that would kick off the 'reboot'. (You can set the power failure setting to do nothing, or reboot...it's a fall back method to compensate for the soft switch of newer machines. Older machines had a hard power switch (you push the button, it goes off), the newer machines have a soft switch (you have to hold the button in...(which is another BIOS setting).).

    Along those lines, as an FYI, Windows 2000 gets more involved with ACPI (Advanced Configuration and Power Interface). Some older computers don't have a BIOS to support ACPI, in fact on those machines Windows 2000 will not do a normal install. On those machines, you have to hit the (I think) F6 key (maybe it's F7) during the initial installation screens. This sets a flag in the installation process which tells it to NOT install/use ACPI. You may be dealing with a BIOS that has ACPI, but it's not a 'good' version. (just hypothisizing! <img src=/S/grin.gif border=0 alt=grin width=15 height=15>).

    Re: Win2K shuts down and restarts

    The auto reboot on power failure is disabled in the BIOS. That was one of the things I came across when I was checking out FAQs. Also, this is one of the machines that turns on and off at a single press of the power switch.
    I did discover something else, though. I originally said that the computer appears to completely power off and then restart. I have to requalify that statement now, because I just noticed that both the CD-ROM and CD-RW drive lights remain on during the few seconds when the computer is powered down.
    Don't know why I hadn't noticed that before, but, maybe that offers a clue to somebody as to what it is that's causing the reboot.

    By-the-way, thank you all very much for continuing to help me on this one. I'm no newbie to computers, but it's obvious that I've got a lot to learn about Win2K. -- Jamie <img src=/S/confused.gif border=0 alt=confused width=15 height=20>

    Re: Win2K shuts down and restarts

    Ew Ew Ew....there's your problem. This may sound silly, but didn't your machine just shutdown to a screen that said 'It is now safe to turn off your computer' (back when it was running 98)?

    It should have, if you have an AT powersupply (I think AT is the hard switch, which is what you have, and ATX is the softswitch).

    I am willing to bet that you have an ATX capable motherboard, but you have an AT power supply. (I have seen motherboards with power 'plugs' for both)

    If that is the case, Windows 98 may not have detected the capablity, and thus you didn't have problems. Windows 2000 HAS detected the ACPI capability of the motherboard, so what is happening, is it is sending the motherboard the 'shut off' command, but since you have an AT powersupply, it is not powering off, and thus is just rebooting.

    I see you have two options.

    One, remove the ACPI capabilities from Windows 2000. This may be easier said than done. I would be willing to bet that the only way to do this would be through reinstalling it using that F-Key 'option' that I mentioned. Do some research on the knowledge base...you want to look for disabling/unstalling ACPI or APM.

    Two (probably the easier and more useful solution.). Open your case and verify whether I am right or not on your motherboard. AT and ATX powersupplies plug into your motherboard, but they have different connectors. They look pretty similar though, both should be pretty big 'white' plugs. If you have one 'set' used, and one not used (that will probably look a little different), then your motherboard can accept both types. If that is the case, just go and buy an ATX powersupply (they should be pretty cheap). The only trick on doing that is that you'll need to do a little research on your motherboard, to find out where to put the 'plugs' on the ATX powersupply, to activate the 'shutdown' and restart jumpers on the motherboard.

    Good luck..... <img src=/S/evilgrin.gif border=0 alt=evilgrin width=15 height=15>

    Re: Win2K shuts down and restarts

    When I ran Win98 (and Win95 prior to that) on this PC, the computer would power down without any problem (No message or pressing the power key required). This indicates that the documentation I have from Gateway is correct - the computer has an ATX power supply.
    That said, however, this is a nearly seven-year-old computer. Is it possible that the power supply (or something else) is beginning to falter and this is the first sign of impending doom? <img src=/S/doctor.gif border=0 alt=doctor width=25 height=33>

    Re: Win2K shuts down and restarts

    Aha, well that flips my theory around a bit! <VBG>

    Does you're computer shut off okay when you hold the power button in? (I'm a little leary that you said it shuts down with one push. Is that one quick push (which would work on an AT P/S) or is it a slightly extended push in.....then release? The timing of how long it waits for the 'push' may be an issue. However, it is more then likely that either the motherboard has a fault, that isn't letting the OS kick the P/S offline, or Windows 2000 isn't playing nice with the motherboard.

    Re: Win2K shuts down and restarts

    One quick press will do the trick (power on or off), but it will let me hold the button in and hold it as well (if I wanted to). There's no "click" and the button does not stay depressed or out to indicate power on or off. It's just a "mushy" button (as a friend of mine used to describe them).

    Re: Win2K shuts down and restarts

    That is a soft switch. It is just pushing in a contact, which once it makes a connection, the P/S shuts off....there should be a setting as to how long you have to hold it in, or a setting for a quick press versus a few second press.

    Re: Win2K shuts down and restarts

    Is that controlled from the BIOS or elsewhere?
