Q: i want to know what is the model of my video card and sound... i cant know from device manager cause i formatted my pc please help .. ?
A: Just reinstall XP and it will run (badly but it will run) with the generic drivers. Next install and run http://www.cpuid.com/pcwizard.php, it will give you every detail about your hardware. All you have to do now is to find the drivers (with the help of another pc if you don't have a working network) and install them.
