first thing I would suggest would be a sytem restore, this may sory your problem and other problems caused by the deletion of files which you may not have come across yet. Goto Programs->accesories->system tools and select system restore. Follow the prompts which appear on the screen and see if that solves your problem.
If the system restore doesn't work, then goto control panel->device manager and look for any items with a yellow triangle containing an exclamation mark, these are items which are experiencing problems. Right click on the problem hardware and select update driver software. The system will now do a search for the drivers that are required. Hopefully, windows will find the drivers you require and all will be good. If windowns fails to find what is needed, then it may be necessary to go to the manufacturers website, look for any identification for the hardware in the device manager and use a search engine to look for drivers or, if your pc was purchased as a ready built machine, try the manufacturers website of the pc itself (e.g. Gateway/Dell/Emachines)
1-check the device manager 2-in sounds and ... look for a yellow symbol 2a-If a symbol appears try to update the driver or disable it. 2b-Restart (at boot the Os will try to recognize the device and auto install the driver. 3-test your speakers in other PC
I would want you to tell me if your Laptop feels hotter than usual.
If so... this in combination with the Boot device not found message means you may have two problems.
1: The hard disc is failing
2: Your cooling fan isn't working
Either one could cause the other to fail. If the hard drive is
overheating the cooling fan may not be able to keep it cool enough to
If the cooling fan isn't working properly or the cooling vents are
clogged the hard drive and/or the intergrated circuitry could be
If you do not sense any over heating.
You hard drive may have crashed, if you have another one you can put in the laptop to see if it is recognized.
Would help to have some sort of disc you can boot off of that would recognize
a hard drive such as a Linux live CD or Hiren's boot CD or some sort of
PE disc. Maybe a Windows install disc. to try and find out the cause.
Your audio drivers must be corrupted....you must uninstall your drivers
1. control panel
2.hardware and sound3. device manager
4. right click your sound drivers..example:soundmax
6. reboot your computer it will automatically reinstall them. and you should have audio again
Nothing wrong with your USB ports. MagicJack has changed your audio and driver settings so it can use the sound system for phone calls. The changes exist whether the Jack device in plugged in or not. You can confirm the problem by uninstalling MagicJack and reinstalling your sound drivers. Should fix the problem. You'll probably need to contact the maker of the MagicJack device for a workaround. Might be something specific to your laptop/operating system.
The NEC LaVie series was only released in Japan. Direct driver support for this model from NEC is only in Japanese if you can read it. Your sound device for this model is 'Soundmax AD198x ac97'. You can do a search for the newest driver though, I found several links to it.
- Open the Control Panel - Open Sounds and Audio Devices - Open Hardware
Look for a device with some name and model number with 'Audio' behind it. This will be the maker of the sound hardware.
Close the two latter functions and open System - Open Hardware - Open Device Manager - Locate Sound, video and game controllers and open - Locate the name you found previously - Highlight and delete ( or uninstall) it
Restart your PC.
This should force Windows to recognize it again and look for and hopefully find the device drivers for it.
It is possible that as often happens, Windows just shot (corrupted) the device driver for the heck of it.
If this doesn't work, you need to run an online scan of your system or run your current AV program to see if something is tinkering with your sound facilities.
