When shutting down computer the computer hangs on windows is shutting down
SOURCE: sony vaio operating system not found when computer
You can try running the installation/recovery disc that came with the computer or the built-in recovery system (if it has one) to try and repair the windows installation. The problem is if the computer is saying that the operating system is not found then critical files got deleted from something like a virus or the hard disc drive has stopped working. You may have to do a format and re-install of the windows OS.

ur boot files are being corrupted either there is a trojen or a virus that's preventing the Win from working.
do this...when u switch on the machine press F8 function key and try to load in Safe Mode. if u can do that then get Tuneup Utility from my website (download page) www.sureshayyar.110mb.com
install and run the cleanup process...1n click maint in that does a good job...use all the tools in that and get ur machine to working....
else u need to boot from a Win CD try do a repair of ur OS....
else let me know...we go to plan B

This looks like the system is not able to sustain itself on the battery power. I have a doubt here. Is it a new or an old laptop. Either Case we have to suspect the battery charging and battery condition. One another reason could be that the battery contact is not good. But this could be of the least chance as the manufacturing of such devices would be perfect in all standards. Lets check the battery power first.
A sony Vaio never operates if the battery is not detected or the battery is not charging, while the system is up and running, you can see a small picture of the battery in the system tray which is at the right bottom corner of the screen. Run your mouse over the same and you will find a tooltiptext message and you can see if the battery is charging or not. If not, your hardware has a problem. If its charging but the battery charge is not increasing, then you have a battery problem. If its a battery problem and that the system is under warranty, you can well get a replacement for free. Hope this resolves the issue. Good Luck.
Testimonial: "Thank you for your help - I really appreciate it! My computer is 3 years old, so I suspect the battery is defective. "
