I reformatted my hard drive because of various virus problems now I don't have any sound. Hardware manager lists "no sound device." Dell driver website does not give me a driver, just updates for drivers. I can't find a driver for this computer (Service tag 9GNC761).

This problem can also be due to the corruption of display drivers// assuming that you have checked the contrast and brightness do this step:- goto device manager// click on the display adaptar + sign and on the pop-up driver right click and select uninstall//
once the driver is uninstalled then restart the computer and check//
if that doesnot work then you can also upgrage the grafic card by going to the web site// even if this doesnot work then 100% the problem is with the notebook screen// contact best buy or wallmart or the retail store from where you have bought the notebook//
To format your hard drive, insert the installation DVD(Vista) and go
through the options until you get to choose which partition to install Vista on
and just click the button at the bottom that says "Format".
I'm not a great fan of USB ....ever since a USB external hard drive decided to become undetectable halfway through a back up once ....
Since the problem occurred after moving the PC, the first thing that comes to mind is that some wiring has come loose .... but as it's a laptop that seem hardly likely.
Have a look in Device Manager (Control Panel/System/Hardware/Device Manager) ....see if there are any yellow warning marks next to any of the USB devices.
One trick that often works in these cases is to uninstall all the USB Root Hubs in Device Manager (right click each one and select uninstall/remove), then reboot the pC and let Windows reload the devices. Don't ask me why ....but this works 90% of the time.
This can be caused by a bad memory chip, but most of the time the hard drive has failed or bad sector that it's unable to read from. If your machine has a diagnostic or hard drive test in the bios, run it. Some also have a memory test that you can run. If yours does have these and any part of the hard drive or memory test fails, the there's your problem. If you don't have these, the start by removing the memory and trying them one at a time. If this doesn't work, then reformat the hard drive and reinstall the operating system. If you have any problems during or after the format and reload, then the hard drive has failed and will need replaced.
