Windows 7: Help? No Sound from Internal Speakers!

Hello there from the Midwest! So I recently had a virus which took out one of the drivers on my computer, thus not allowing me to Start Windows Normally, in Safe Mode with Networking or anything other option. So, I upgraded to Windows 7 Ultimate. Now, everything is running smooth, except I have not sound coming from my internal speakers. I tried going here, Control Panel\Hardware and Sound\Devices and Printers , to which I saw that my HP Compaq DC 7800 needs troubleshooting. I right click to do troubleshooting and it finds that I need PCI Simple Communications Controller as well as the PCI Serial Port. I tried to install the fixes and that was no luck! Now my question is... What in heavens do I do? I really miss listening to my music every morning.

This is your computer?
You installed the 32bit or 64bit version?

And you've gone to this page?

Win 7 Ultimate wasn't listed so I followed the links from Win 7 Professional (32-bit).

It looks like the first two upgrades for Windows 7 are BIOS and Chipset drivers and that sounds to me like a good place to start as both of these will help Windows 7 correctly identify the hardware on your computer.

I would first install the chipset drivers which are basically inf files that correctly describe the hardware configuration. A BIOS upgrade is a little more tricky if you've never done one before, I would visit the Hardware & Devices sction of this forum and post a question (re: BIOS Upgrade) there.

Don't know if there's an easy fix as it looks like a couple of things need to be updated first.
Go for the chipset drivers and see if Win 7 recognizes your hardware.

Also, one other question... did you install Windows 7 over the top of your previous operating system or did you wipe (format) the drive and do a fresh install.

The first two

I installed over my Windows Vista Business, 32 bit. Mine looks more like this >> HP Compaq Business Desktop DC7800 http://lh3.googleusercontent.com/oxU..._B1GAvn-GUhe3y The rest of the specs I could pull up are in my profile. My friend did the installation, so I think that he did the 32 bit installation. The thing is the it doesn't even recognize my audio hardware when I troubleshoot. and, "I tried going here, Control Panel\Hardware and Sound\Devices and Printers , to which I saw that my HP Compaq DC 7800 needs troubleshooting. I right click to do troubleshooting and it finds that I need PCI Simple Communications Controller as well as the PCI Serial Port."

If you want to check which version you have, open the start menu, right click My Computer and click properties. Look at what it says for system type.

To quote myself, from another thread,

Sound Output

HP doesn't list any Windows 7 drivers for your ADI 1884 audio chip. The Vista drivers may work.

Good luck.

Seriously, thank you SO much Bobkn. The driver worked after download and restart of system. I am very grateful for your help! (:
