Do you have a system recovery disk or a windows Xp or what operating system you have disk, I need to know some things like what you did, How you lost your operating system, So we can find a way that hopefully you won't loose all your files.

Operation system not found

Hi and Welcome to Fixya

THis means that the operating system of this computer is already corrupted especially the boot manager. This is the file the requires your computer to boot up to windows. You can still use the computer but you need to reinstall the operating system again by using the recovery disk of the computer.

Thank you for using Fixya!

My webcam was working yesterday and it just stopped working my sony vaio model number is vgn-ns135e

assuming that the camera is built in the laptop will need to get to the support site the model and the number and after that select the operation system in use...and download the camera driver again ..and run it for installing ...after that reboot the laptop and will be fine if it is not damaged physically ..
here you will be able to find it after selecting the operation system that you use..
Another way to fix the issue to roll back the operation system settings to an earlier date (when it worked) ..using the system restore from the all programs /accessories/system tools..system restore..

I've reformated my sony vaio vgn-n11s/w and now it says that no video card is found. i've installed all the drivers again but still no video card. any help?

If you are sure that the driver you installed is the correct one ...check the card not to be disconnected from the ribbon or so...If the computer sees the video card in device manager ..but it is in yellow with a ask sign means that the driver you use is not the one you need...
to get the correct driver ..go to the support site ..and download it from there after you selected the model ..number and the operation system you use.. If after you format it changed the operation system will need new drives..If the card is not detected at the device manager ..than it must be corrupted and you will have to change it ..
