Power shutting down

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

Take the laptop back, this sounds like a motherboard issue or improper factory install.

Hello

First of all press ALT+CTRL+DEL and start Task Manager, there is probably some application (or other process) that is not reponding. You can kill them to let the shutdown continue, and know what is causing the problem and maybe find an update for it.

Also this means that your computer has not been rebooted properly since the installation of important system updates. If you have "Automatic Updates" scheduled on your machine, these updates could have downloaded and installed without your knowledge. To fix this issue, let the updates finish installing, reboot and then shut down your computer as normal.

Click "Start."

Click "Windows Update." Click "Install Updates" to begin the installation of any updates that have been downloaded to your Compaq Presario. When the "Restart Now" button becomes available, click it once. Your Compaq Presario will shut down Windows, finish installing the updates and then reboot your computer.

Click "Shut Down." Because the updates have finished installing and have been installed properly, your Compaq Presario will now shut down normally and will not immediately boot back up.

Hold the power button in for 10 to 15 seconds for hard shut down if that doesn't work unplug power for about 5 minutes then plug power back in and see what happens

Hold the power button until the computer shuts down.
Restart and press F8 key repeatedly until you get a start up menu.
Select safe mode from the menu.
After the computer boots up, and you are at the desktop, go to my computer and select properties of the C drive (your system drive). Select tools from the tabs, then defrag. When defrag finishes, select check drive for errors and select the box, to automatically fix errors, and then ok, and yes at next window, allowing the computer to schedule the error check at next boot.
Reboot and allow computer to scan the drive.
After it finishes, you will continue into windows. Allow windows to boot. After it finishes, attempt to shut down again.
If it works, you fixed it. If not, you have a driver or program that will not quit, and you will have to research further to find out what is running and why it won't quit.

try and format the primary disk and go for a new installation of the OS,or reinstall the OS by using a bootable disk

If you are updating windows xp and it says installing updates when you are shutting down your computer, you should let it finish, even if it tales overnight. depenind on how many updates you have, better to go to the updates web site and do it from there. after they have installed then you should be able to do a restart on your computer and compleate. Any thing ells you are best off contacting MicroSoft

Try this:

Shut down the laptop, disconnect anything plugged into it, remove the battery and hold down the power switch for 15 seconds (with no power or anything attached to laptop).

Reconnect A/C power and power it back up. See if that works for you.

If not, when you get booted into Window, go to Start > Programs > Accessories > System Tools and click on System Restore.

Follow the prompts and choose a bold date back to a time prior to when you lost sound. When it reboots, you will probably have sound.

Let me know if you need further help.

This happens because your CPU is overheating, open your PC and blow any dust off the openings and CPU/Power supply fans, if you think one of the fans is not working... replace it.
