If this same computer Shut Down fine before: Whenever you load Windows from scratch, after Setup has finished you must load all of the drivers for your mboard so that Windows has the proper info about your mboard, including it's ACPI/APM support. If you haven't done that since the last time you loaded Windows from scratch, do that, and your mboard should Shut Down fine. Enabling or disabling ACPI/APM in the bios has no effect on whether the mboard will shut down properly in Windows on any mboard I've tried that on. I have one mboard, and know of several other ones I have worked on, that have that turned off in the bios and Windows will Shut Down fine.

Tubesandwires, thanks for your explanation, now, in order to get the proper motherboard drivers, as this PC was a win 98 machine, could I use a prog such as Everest to give me the needed information I need to get the proper drivers? Thanks Hopefully my advice will help you...Please post back with your results....thanks

Some of the old mom board technology doesn't support ACPI/APM shutdowns. If that machine is an old 350, the BIOS ACPI/APM probably won't support it... You might want to see if there is a BIOS upgrade for that Motherboard that supports autoshudown. let us know if you ever figure out something that works. I see geeky people.... wait.. that's my mirror!

scootr, I used Everest and the motherboard chipset is intel 82440BX/ZX and I can't for the life of me seem to find those drivers. Any idea besides the intel site? Thanks Hopefully my advice will help you...Please post back with your results....thanks

All 440 main chipset drivers here: http://downloadfinder.intel.com/scr... Other Intel Rochester RC440BX downloads: http://downloadfinder.intel.com/scr... DO NOT flash your bios if your system is working fine! You should never flash your bios unless you find specific info such as in the release notes for the update that mentions a cure for a problem you are having.

Tubesandwires, I'm confused on the 2nd link to decide which D/L I need Just the Win 9's, NT 4.0 & NT 3.51, OS independant, All Operating systems are listed. No WinXP is listed so which one would I get? I hope the D/L will cure the shutdown problem Thanks Hopefully my advice will help you...Please post back with your results....thanks

You only need to load the main chipset drivers (INF update utility) at the first link above to load the support for ACPI/APM and probably get Shut Down to work properly. This mboard is old enough that XP may have the support built into it correctly detect the video and audio and install the correct drivers automatically. If they seem to work fine, that's probably your case. If XP doesn't know what they are let me know and I will attempt to point you to where you can get the drivers. ..... Support for the Intel® RC440BX Motherboard http://support.intel.com/support/mo... Technical Product Specification - is the mboard manual. It's dated Sept 1998 - there was no Win 2000 or Win XP, or newer, back then. Motherboard Specification Update - is the updates to the manual - usually it's mostly descriptions of problems and whether they were fixed in later bios versions. In the Technical Product Specification - your video is Nvidea RIVA 128ZX 3D Multimedia accelerator Audio is probably BOTH or EITHER of - Crystal AC97 CS4297 audio codec and/or - Soundblaster AudioPCI 64V digital audio controller/ In the mboard diagram in the manual, if you have the CS4297 chip in the position shown, you have the Crystal AC97 audio. If you have the Soundblaster AudioPCI 64V audio controller chip (it may have been optional) you have the Soundblaster sound. Note that many made by Intel mboards may have either an Intel bios version or a brand name system bios version. In the bios string, e.g. xxxxxxxx.xxx.xxxxxxx , the first part is unique to the mboard model and doesn't change, the second part is a code that varies depending on who the bios was made for and doesn't change for bios updates for that company, the third part varies according to which bios version it has. If the bios was made for some company other than Intel, the first part is identical, the second part is the code for that company rather than Intel, and the third part may or may not be the same as it is for Intel bios versions. In this case, the first part is always 4R4CB0XA, and the second part is 86A for Intel, so if the bios version was made for intel, it is like so: 4R4CB0XA.86A.xxxxxxxxxx. The Motherboard Specification Update lists only Intel complete bios strings.
