Power went out, now no internet or sound on PC running Vista

ShaggysMine
The breaker flipped on power running to my PC's and now the computer running Vista will no longer recognize the modem or connect to the internet. It has also lost all sound to the speakers and doesn't recognize them. I have another PC running Windows 7 and it is working fine and is able to get online. Any suggestions? .

    Check Device Manager and see if you have any devices with a yellow "?" or "!".

    If so, you may need to reinstall device drivers, or a fresh reboot may fix it.

    An easy way to force a drive update is to uninstall the device and then reboot so that Windows can find new hardware and install the driver again.

    Have you tried a different set of speakers? Could be as simple as a power supply failure from the power surge.

    You say can't find the modem? Do you connect directly to a cable / DSL modem, or do you connect through a router?

    If a wired connection, it is not impossible that the port is damaged.

    For a wireless connection, it is not impossible that the RF transmitter has failed.

    Open network connections, and check the connection status. If you have no connection, check for any indicator lights an the Ethernet Jack, or the Wireless status light on the computer.

    Post back with the make and model of your computer and any peripherals that are connected for the Internet connection.

    One last thought, if you have an outlet strip that only some of your equipment is plugged into, make sure that the breaker on the outlet strip did not trip.

    Okay, there are no yellow ? or ! in Device Manager and all says it is working and has the correct drivers.

    The speakers work fine on the other PC I have on the same network as so does the ethernet and port on a router.

    All the lights are on and the power strip has everything working. The Message for Audio Service Not Running says This computer cannot play audio because the Windows Audio Service is not enabled. Would you like to enable Windows Audio Service? When I click to yes and got to the Sound window it says Realtek Digital Output and Speakers are enabled/ There is a check on the speakers, but not on the Realtek icon.

    The computer is an HP Pavilion a6110n PC. There os the monitor, wireless keybord and mouse, speakers and external harddrive that was not hooked up at the time it shut down.

    Hope that answers your questions. I appreciate your time.

    Okay.

    I have seen some weird problems when a Microsoft driver update is installed.

    Open device manager and check that you have the correct driver versions as per the HP driver list for your computer.

    You usually need to click on the driver details button to get the driver version.

    Driver - Audio(?1)
    Realtek High Definition Audio Driver Update
    2008-03-01 , Version:6.0.1.5548, 12.34M

    NVIDIA LAN Driver
    2007-06-20 , Version:65.7.4.0, 1.08M
    Summer 2007 original drivers for the NVIDIA LAN solutions.

    If you have different driver versions, download the drivers from the HP website and transfer them to the computer.

    http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=2093&lc=en&cc=us&dlc=&sw_lang=&product=3436818#N367

    Uninstall the device from device manager.

    Then install the HP driver.

    Thanks so much for the information. When I uninstall these, a window pops up and has a box to check to delete the driver software for the device. Do I check it or leave it alone? Also, I am looking at uninstalling Realtek High Definition Audio and NIVIDIA nForce 10/100 Mbps Ethernet. Do those sound right? I just don't want to do the wrong thing so I want to ask first. Hope that's alright. I did download the drivers from the site and have them on the other PC so I will wait for your reply. Thanks

    Those are the correct two devices.

    You can choose the option to uninstall the driver files as you have a new driver ready to install.

    You might double check that the speakers are plugged into the correct jack, the green out jack.
    Also, these are powered speakers. Most output jacks on computers can barely drive headphones and will not drive unpowered speakers.

    For the network port, double check that the connection lights at the jack the cable plugs into turn on.

    The more I think about this, the more I suspect that you had two hardware failures at the same time. Both the final output stage of the speaker out, and the Ethernet output.

    Is it possible that the cables for both were pushed hard into the computer and damaged both jacks.

    Still, it will not hurt to do a driver refresh.

    But, if reinstalling the drivers does not fix the problem, there is a high possibility of a hardware problem.

    Well, I either did it wrong or it is something worse. I hate that, but I guess I'll have to find a computer expert. Thanks so much for your time and help.

    Sounds like the Vista OS files got corrupted during the power outage. Try to run SFC /scannow (click START and in type that in the search box) and it will scan the system files for any corrupt files and replace if necessary.

    Bapster, I clicked Start, then Run and when I typed in SFC /scannow and hit OK a small black DOS-like screen flashes, but then disappears. Is there anything else I can do? Thanks for this suggestion.

    Make sure you right click and run command or cmd
    As Administrator and then try the sfc /scannow

    The message I got after typing in sfc /scannow as Administrator is "Windows Resource Protection could not start the repair service." =o(

    Most of the time when I run into this kind of issue system restore puts things right.

    That was what I tried first and it says there are no restore points, which there should be, and System Restore cannot start. Thank you though.

    Just had a new thought on this.

    If the PC was off, but plugged in, a weak CMOS battery could cause the BIOS settings to change.

    Boot up the computer and enter BIOS setup.
    Look for the integrated peripherals, and set the Sound and Network adapters to disable.
    Save and Exit Setup.
    Enter BIOS setup again, and enable the devices.

    In the PC Health section, you may be able to see the CMOS battery status or voltage. Any reading less than 3.0 volts indicates that the battery needs to be replaced.

    I thank you so mush for all your suggestions. They all make sense to me, but I have not gotten the internet or sound to work yet. I can't run anything to see the PC Health report so I don't know about the CMOS battery. I did see that I can check it with a battery tester. Do you think that could be an issue? I will check it. Thanks

    Thinking about this, if the PC was off when the power went out, a weak CMOS battery is the most likely problem.
    These are typically CR2032 coin cells and are nominally 3.0 volts. A good battery should measure 3.1 to 3.3 volts. Anything less than 3 means it needs to be replaced.

    If you replace the battery, you will need to enter CMOS setup and check the settings. You should be fine choosing the recommended or default settings.

    The PC was running when the power was shut off to it. I'll check the battery. Thanks again.

    As a support tech, several times end users had no speaker output and for some reason their system's audio had been set to "Mute". As soon as I unclicked "Mute" everything returned to normal. Your problem could be as simple as that.

    Reboot. Hold down the F8 key. Select "Safe Mode". Sometimes things get fixed automagically by running Safe Mode. It is worth a try.

    I have a client with a Toshiba Laptop running Vista who would lose her Internet connection periodically. Usually I would remove the device and re-install the driver. After a power outage, no matter what I did I could not get the network adapter or the wireless adapter to work( I even tried a USB wireless adapter). I backed up her profile and did a factory restore and everything worked fine. I have seen this on a couple of Vista machines. Sometimes, with Vista, it is best to cut your losses and just back up and re-install.
    Time trying to get networking functioning again: 3-4 hours.
    Time to Back up and re-install : 1 hour 45 min.

    So, if I have all my files and programs on an external hard drive, are you saying I should do a Recovery and then put the files back on my PC?
