Help No More Sound

Ok i got some sort of virus like 2 days ago and it just randomly started deleting stuff and disabling stuff so i restarted and it wouldnt reboot on anything. So i just formatted and reinstalled XP Home. Now i cant play any sound at all. When i go in to device manager under ''Other Devices" Next to it is a question mark and inside that menu it says Ethernet Controller and PCI Device and Next to those there is an exclamation point. Can any of you help me?

 

whats your system manufacturer and system model?

Start/all programs/accessories/system tools/ system info

 

I know.

Just re-install all your drivers. If you have a factory pc you would have got driver discs. Just install the sound/network/ethernet/gfx/etc drivers.

 

System Manufacturer: Dell Inc.
System Model: ME051

 

Nevermind i downloaded the sigmatel audio drivers from dell.com and now its fixed. thanks for your help.
