Here, recently I have got a problem with my computer. My OS got crashed, and reinstalled the OS. Now it does not recognise the sound card, wireless and it does not connect to internet even I connect to with the  cable.
My guess is, it is something to with drivers. But would not drivers come with OS itself?
OH BTW, my computer is  Dell inspiron 2200. OS is XP sv pack 2.
could u guys help me figure out what went wrong with my computer?

i had the same problem couple of months ago....ya need to re-install yo wireless card,bluetooth,webcam,sound card.....in my case,i took my laptop and the CDs to IT department and they did it for me.

guys, u have to installed sound card driver and others one too.

you might have the driver cd somewhere lying around, find it and use it to install your drivers.

if you can't find it, go to this website (yes, click me!!) and download the required drivers.

good luck!
