+ 0 Votes Check TheChas 1 year ago 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.Chas + 0 Votes Check Driver Versions TheChas 1 year ago 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 Update2008-03-01 , Version:188.8.131.5248, 12.34MNVIDIA LAN Driver2007-06-20 , Version:184.108.40.206, 1.08MSummer 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#N367Uninstall the device from device manager.Then install the HP driver.Chas + 0 Votes Correct TheChas 1 year ago 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.Chas + 0 Votes goto a command prompt and type in sfc /scannow Bapster 1 year ago Make sure you right click and run command or cmdAs Administrator and then try the sfc /scannow + 0 Votes My first crack would be system restore gharlow 1 year ago Most of the time when I run into this kind of issue system restore puts things right. + 0 Votes BIOS Setting and CMOS battery TheChas 1 year ago 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.Chas + 0 Votes Check to be sure the speakers are not set to "Mute". AtlantaTerry 1 year ago 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.Terry ThomasPresidentPC Tech SupportAtlanta, Georgia USA + 0 Votes Vista loses drivers ITKimK 1 year ago 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.
