I've recently replaced my motherboard for an MSI Z77 MPOWER motherboard and replaced my faulty PSU for a Corsair GS800 PSU.

Before I had no problems switching on and switching off the computer; you could say it works normally, but when I replaced both of those items listed above, I've found that the computer when you command it via Start in Windows 7 to shutdown or restart or when an update says you need to restart, the computer would not fully power down.

When I select to shut down, often or not the operating system would go through the process of shutting down, then I get indications on my monitor that there is no signal, which is fine, but the computer hardware is still on.

When I select to reset, the operating system often hangs and will not restart.

I still have a computer that is working but is worried that over time if I manually have to hold the power or reset buttons on the case I will at some point may corrupt the operating system.

Anyone know of a solution or knowledge of such problems.

Also note, I have updated the BIOS and drivers on the computer itself.

So you fitted a new mother board, and a Psu.
And did a clean install of windows?

Because if you did not all of the drivers windows has relate to the old board.
And it`s APCI. used to put the board into sleep mode, reset it, or shutdown windows.

If you did install a fresh version of windows, then you need to go into the bios and setup some power modes.

Look up APCI power modes S-modes of the bios.

Windows signals the bios to perform power downs of the system, restarts, and sleep modes. but if not set up right in the bios you get the problem you are having.

One last thing, if the board was fine before the bios update.
And then stopped working.

You need to flush the bios via the jumper pins of the mother board back to factory defaults.

To fully complete a bios update and flush any old bios information out.
As it can cause a conflict in settings.

I've been trying to remove the drivers for the other board but can't seem to be able to do that.

It's not a clean install of the operating system but will look into how to remove the other drivers

There is no point.
Since the ACPI configuration is setup in windows.
When it is installed for the first time.
Its trying to communicate with a bios of another board, with a different bios.

You need a fresh install of windows. All of the windows settings for the ACPI are wrong.
That is why you have to do a fresh install of windows when installing a new board.
It`s a golden rule, do a fresh install and it will all work fine.

During Windows Setup, ACPI is installed only if all components present during Setup support power management.

Since you did not install a fresh version of windows. it was not setup for the new board.
So windows cannot use it. the settings are wrong it is trying to use the old Acpi settings for the old board.

I forgot to add that changing a motherboard is classed as a major upgrade so may render the current windows licence key invalid.

And you may have to purchase a new windows licence key.
It will depend on the version of windows Oem ect or retail.

At least you know what the problem is now.
Good luck.
