After a recent power outage (computer was on when power went off), when I booted my computer up again, there was no sound and the speaker icon did not appear in the taskbar systray like it usually does. I tried to troubleshoot with my limited computer abilities by looking the Sounds and Audio Devices>Hardware>Properties. There was a yellow circle with an exclamation point in it next to this device: Intel® 82801 BA/BAM AC'97 Audio Controller. Also a message "This device cannot start (Code 10)". I don't have any disks for this computer (HP Pavilion 750n desktop running Windows XP as an OS). I wanted to know if this is likely a driver (if I even have one anymore) or a sound card problem. I already tried to update the drivers as is recommended on many troubleshooting Web sites. All this did was change the Intel® 82801 BA/BAM AC'97 Audio Controller to Sound Max Integrated Digital Audio. Also doing a system restore was ineffective. Some troubleshooting sites mentioned re-setting the BIOS, but I don’t know how or what to do about them. If a sound card is shorted because of the power outage, this probably wouldn’t help, would it? What can I do about it (if anything) and could the power outage have caused it? I've run a virus scan with it and nothing discovered. Also nothing with CCleaner, Malwarebytes or SpyBot. Would getting an external sound card work around this, or is my sound system just shot? Attached is a photo of the inside of my tower with a red arrow pointing to the connector where I plug in the speaker jack.

Uninstall the sound which has the yellow exclamation point in device manager and restart your computer. Windows might be able to reinstall the sound for you. If this doesn't work.

Download Everest system diagnostics free from here http://majorgeeks.co...d.php?det=4181. Run the program and find out what exactly what your sound is. Whether it's a sound card or on-board sound, make, model etc. Once you've found this out using Everest. Search and install the driver you need for your sound.

Okay - I ran EVEREST. Here is a screen shot (click on the thumbnail to enlarge). Since I'm not too computer savvy, please interpret. Thank you.

If it still too small to see, I opened Multimedia, then PCI/PnP Audio. One device is listed:
Intel 82801 BA ICH2 - AC'97 Audio Controller [B-5] Type PCI

However, I'm not sure what to download - both the chipset AND audio driver or what and where to download. Sorry to be such a pain. I'm certainly no computer expert.

Can you post a picture of your motherboard details from Everest please? Does your computer have a make and model number?

Edit: Pictures are loading ok now. I turned off my pop-up blocker.

If the driver scan does not work we need to try something else to get the proper info on the board.

Lets see if we can get some system information.

Download and install PC Wizard 2010

Run the program and it will analyze your computer and then display the results.
In the upper left hand corner click on the floppy icon.
You will get a save as screen.
Change the range bullet "only this selection" to be "selected category".
Make sure that text is selected for format.
Click on ok and you will be given a spot to save it to.

Attach it to your response.

I ran that link Mike posted to updating Intel drivers, but when I did, it said "This device is unknown or unsupported". Here a screenshot of the PC Wizard scan and the Device Manager showing the problem
