Have you tried updating the BIOS firmware? If the problem persists after doing so you might as well contact Dell about this because it's not a common problem.

hi thnx for the reply.. i did not try it yet. can u tell me the procedure of updating the firmware sir?.. thnk you

I could not find the product page of the "pp03s" on the dell website so you'll have to figure that one out yourself. To be honest, i've never updated a Dell BIOS before but the process is something like placing the .bin file with the update software on a disk and boot from it. Search the dell website or google for "dell bios update pp03s" and it might help you out.
