I have an Acer Aspire 5520 and I think I have a BIOS problem. My computer has stopped detecting my sound card, stopped detecting the CD\DVD driver and one of the USB driver too. What could it be? I can't do the e-recovery from DOS.
Since your problem can stem from a number of problems, you need to conduct some troubleshooting scenarios to try and fix it. Read through all of the suggestions and then try them in any order one-by-one until the problem is fixed.
Use the Device Manager to Check Device Status
First, let's check to see if your computer has noticed any problems with your sound card, CD/DVD drive, or USB drives. You will need to access your "Device Manager" to do so. To open the dialog box for "Device Manager" follow these directions (or a variation depending on your version of Windows):
1) Choose "Start" form the bottom of your screen.
2) Choose "Control Panel."
3) Choose "Performance and Maintenance."
4) Choose "System."

5) Choose "Hardware."
6) Choose "Device Manager."
Look through the dialog box that pops up and search for mention of any problems with the drive. You might see the word "disabled" or a warning sign. If the "Device Manager" indicates that the drive isn't working, select "Troubleshoot" and search for a solution. In many cases, this fixes the problem for you.
Reinstalling Device Driver
You can uninstall the device in question directly and then reinstall it. Typically, this fix works quite well. If you want to do this through the "Device Manager," just uninstall any of the devices that were marked disabled and scan for new hardware changes.
Update Device Driver
If your existing device drivers are too old, you may need to update them. Visit the manufacturer's website for each device and check to see if any new updates for the drivers are available.
Boot up in Safe Mode
You can always boot up in "Safe Mode" and see if that fixes the problem. Just turn the laptop power on, and hit the "F8," "F2," or "F12," key on the keyboard as soon as it starts to power up. You might need to hit the key more than once. Use your mouse to select "Last Known Good Configuration," and press enter on the keyboard.

well, i have a problem like the one state above, but only my dvd isnt recognized. there's no way a s.o. config can solve the issue, the bios itself doesnt recognize it.
i have mandriva in another partition, it cant access dvd drive to.
open the drive, put a disc: the disk will spin, the notebook access led will lite, but nothing more.
i'm thinking update bios, but as i don't have another computer, i wont do that.
