Shut down when i shut my acer veriton 5600g down it just starts up again.......... help

Its possible that the system hit errors when closing down.
Goto "My Computer" icon, Right click and choose properties.
Then choose "Advanced Tab"
Select the "Settings" Button in the startup and recovery option.
You will see a "Restart on System Failure" tickbox.
Turn it off.
Problem should go away.

You need to check the bios so that ACPI is enabled in the bios, so select F2 or DEL on boot up and and this will take you into the bios, choose advance cmos settings and look for ACPI which should be set at enabled to allow windows to shutdown properly, select save and wxit settings for a reboot. Next go to control panel then in powe options make sure the settings for shutdown is enabled to do so when you select the shutdown option on the windows screen.

Restart has always been an option when closing down your machine from windows, when shutting down ensure that "restart" is not highlighted/selected, Windows will automatically select the option selected on the previous shutdown.

I think thats should be a hardware problem. That means the 3.5V ps-on signal is always at 0V level. So you could clean your cmos by convert the battery on the mother board then try again. First of all, check whether there is some dust or some little metal stuff beneath your power button. Regards. Jimmie

The best thing you can do is to reinstall windows. This will surely fix the problem.
