___ A REAL General Hardware Question! ___ (Resolved)

[Blain]

Here's the problem...
After Windoes XP Home goes through it's shut down steps, the HD shuts down, but the CPU fan as well as the ATX PS keep running.
The same MB/CPU combo under Windows 98SE would reboot when the PC should have shut down.

Things I've done...
1. Did a fresh format and load of Windows XP Home on a different HD - same problem
2. Changed MB and CPU - same problem
3. Changed ATX PS - same problem
4. Checked continuity of case power switch (showed closed circuit only when button depressed).

Different MB, CPU, PS and OS haven't solved the problem. Could this shut down problem, somehow be RAM related?


BTW, I DID download and install all the XP updates.

[EDIT] I guess it wasn't a REAL General Hardware problem after all.

I'd update the board's bios and clear the cmos. Usually shutdown issues are ACPI or APM related. Clearing the cmos should make sure that it's not a bios setting. In Device Manager under "Computer" is your pc listed as ACPI Uniprocessor PC ?

Some system specs would help too.

Even two different MBs running two different types of CPUs?
I have tried playing around with the power settings in the BIOS - same problem

Under "Computer" in the Device manager it's listed as "Standard PC"

Like I mentioned before, specs would be helpful.

You can really mess up your windows hardware config when you swap motherboards without following certain steps or reinstalling windows.

I really think you have to simplify things now. Get your original mobo/cpu back in there. (Or whichever you want to keep in the system.

Remove all PCI Cards , unhook all Hard Drives and optical drives. Leave only vid-cpu-ram . Update your bios if available , reset the cmos after doing so. I'd then test the memory overnight with Memtest86+. If everything's ok then install the Hard Drive. Test it with the manufacturer's utility and wipe out whatever exists on the drive. I'd even try the manufacturer's utility " Low level format" option.

Then try reinstalling windows and see what it gets you. " Standard PC" means your pc is not using ACPI which could be your problem there. Is this very old hardware ?

It's a glitch in the Matrix

Thanks TheGreenGoblin, you sent looking in the right direction...

I opened the screen saver tab...
Went to "Power" option properties...
Went to the APM tab...
Checked to enable APM support...
BINGO! :laugh: Thank you

Glad to hear that the solution was relatively simple. And thanks for posting the solution.

A lot of ppl never bother to let ppl know what the problem was and how they resolved it. They simply dissappear leaving us wondering what the problem really was and if we were on the money or not.
