Are you doing shutdown from windows of your computer ?
Or are yoy doing suspend or hibernate.

If the computer is shut down from windows and
the HDD spins up it sounds like something is
faulty with the motherboards powermanagement features.

I am shutting down thru windows. I had a virus a week ago and my scanner deleted it imediately but I am not sure how long it was in my computer, could that have damaged my power management features and do I need to rebuild Drive C.
When I shut down I also unplug to hold down the noise but when I plug it back up hard disk light is on and spinning.
Thanks

Yes that is what is happening and just now happening after 4 years. I Looked over all the material you sent links for but still not clear how to correct the situation, wil rebuilding drive C do the job.

Before giving any advice on that we need to establish
if the computer is suspending when you shut down or not.


IS IT SUSPENDING:
Say if you have internet explorer up and running.
Shut down windows.
If the pc suspends , then when its turned on again it comes on straight to the desktop and the last used applications is still there.

IS IT SHUTDOWN:
Normal booting is shown on the screen , BIOS ,
starting windows etc.

By the way , have you accidently made some changes in the BIOS.

 

[Cliffie]

Never do I shut down in the middle of something However I did have a lock up one day last week in the middle of my searching and had to turn the switch off to get out of that, I ran scandisk after that and defrag.
I do not know what and where BIOS is at, if I changed it I had brain fade which is very often now days but I dont think so. I travel in very familiar trails on my computer and will never realize the full power of it because of my narrow trails.
Thanks again

What i'm trying to esablish is if your computed goes standby.(when you enters Start-Shutdown from windows)
You know the difference between standby and shutdown i guess.
quote:
"When I turn on the power button on it boots right up"
Does this mean that windows is there immediatly
or do you get the black screen with starting windows.

 

[Cliffie]

I know the difference now, boots right up may have been a bad statement, It goes thru it normal routine to get back to windows it takes maybe 1.5 to 2 minutes so it was not in stand by mode I do have a black screen when starting.
Thanks

Try this, right click on my computer and choose properties, then hit the Device manager tab and select "View Devices By Type" at the top. Next find where it says "system devices" and expand it. There should be something here named "ACPI Power Button" and "ACPI System Button" or "Advanced Power Management Support", highlight one of these at a time and click remove and restart your computer so Windows finds them again and reinstalls them. Only try removing one thing at a time though. Hope this solves the problem.

 

[Cliffie]

Okay I deleted "ACPI System Button" and restarted then I shut down for 14 minutes and no startup which usually started at 10 minutes. Just in case later I have "ACPI Generic Bus" is this "ACPI Power Button" or is it "Advanced Configeration and power Interface (ACPI) BIOS". I am looking for exact wording and it is not there but would rather ask than mess up. You have been great to help.
Thanks again

Good.
Do you have any faults in the system .

Can you shutdown from windows in that way
that the computer turns off of it self.
( not the "it's now safe to turn off computer" message
and you have to use the button)

 

[SYAR2003]

I think you should remove them all , restart
and let windows install them back again.

 

[SYAR2003]

Cliffie ? any progress on your issue

 

[Cliffie]

Well no, after deleting the second item under device Mgr, my computer went into the safe mode and I could not get it out so my next move was to use my recovery CD and now have everything back to where I started. I shut down thru windows and after 10 minutes the drive goes MOOoooempd and the speakers go TIC tic, sounds like some rock ban tuning up so the one time I shut down and all worked may have been a fluke.

Must be some hardware issue then .
Motherboard / psu .
A disk drive runs at 12v witch comes frome the psu.
(i'm not sure at wich voltage it would try to start)
When the computer is shut down , all the 12v 's
shold be off.

Is there any blinks in other equipment like
lamps or so when it happen.
Could be that it comes from the AC wireing system / net
some spikes or something.

 

[Cliffie]

When I first shut down there is window on my monitor that blinks for a few minutes "Video Input no signal" it stops blinking after a few minutes.I dont remember it being there before I started having this problem, no other blinking lights. I did rearange some of the cables and plug computer in a different receptacle but none of this was any help.

After I had some odor comming from my computer I took the cover off and it was the power supply humming and was very hot. It is most likely bad and sending a pulse to the speakers. It was the power supply making the noise and not the hard disk. The hard disk amber light was also picking up the pulse and now the Num Lock & Cap lock light is blinking. I will replace the power supply tomorrow. Its a start.
