You probably need the Network & Chipset drivers, but make sure you get the right ones for your model.

sorry i dont understand what is the problem?

You may be exceeding the Hardware limits of your laptop, Win 8 has hardware minimum requirements. See: http://windows.microsoft.com/en-US/windows-8/system-requirements That's a common problem in a OS upgrade. Did you check the Hardware Compatibility list before you installed Win 8? Take a look at this: http://pcsupport.about.com/od/termshm/g/windowshcl.htm First you must ID the Unknown Device, Card Reader is common along with Fax modem, Audio, on a full size laptop. ID the device and download the driver from the Dell website.

have you went onto the BIOS to make sure that the boot options are correct e.g. CD DRIVE 1st priority?

download a new driver of your audio device from dell.com.

Sir,
it is no driver problem but of your Windows ... sometime while updating Windows it get shutdown improperly or say for any reason its update installation stop and therefore this problem occurs so you can reinstall your windows and it would be fine.

you'll need to buy an install disk, from there you just have to format the drive ( or get a new one) and install it on that, once that is done you'll just have to download all your drivers to bring it back up to date.
