My sony vaio desk top pcg-11211L screen shows operating system not found

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

I get no sound on my laptop pcg-7d2l, the headphone jack does not work either.

First make sure you don't just have it muted... seems simple but its happens. Open the volume controls and make sure the mute is not checked. If that doesn't work, try removing the sound card drivers and reinstalling them after a reboot. If both the speakers and the headphones don't work its most likely the drivers, however there is a chance the sound card has gone bad as well. . . Try the driver reinstall and if that doesn't work you will need to have it serviced.
