Question about Sony VAIO VGC-RB50 PC Desktop

2 Answers

Computer will not recognize drivers for ethernet card

After reformatting drive & reinstalling Windows XP, ethernet drivers have been downloaded from Sony's site from 2nd computer & loaded onto USB drive & uploaded to 1st computer, but 1st computer persists in not utilizing these drivers. Bios has been checked to be certain "enabled" is on all related systems. 1st computer will walk through set up for dial-up modem, but will not recognize cable modem via ethernet card. Any thoughts or suggestions? We've consulted with several tech-y freinds & we're truly stumped.

    Bat1956,

    Thank you for your help! There are yellow question marks that appear next to Ethernet Controller, PCI Simple Communications Controller, Video Controller, and Video Controller (VGA compatible).




  • susannej Jan 01, 2009

    Bat1956: Yes, this was all working fine prior to reintalling WindowsXP.

    Kiran_G4E: The drivers are directly from Sony's website, specific to the VGC-RB50. I'm not sure how to remove drivers by booting in safe mode. Can you please explain further?


  • susannej Jan 01, 2009

    Hi, thanks for the feedback. the files I downloaded were auto-executables, and I had moved them from my thumbdrive to my desktop. I'll try the safemode startup and remove my drivers to see if that helps.

  • susannej Jan 01, 2009

    In Safe Mode, I've uninstalled all of the "?" devices from the Other's category within my Device Manager screen. The devices I uninstalled were the 2 video devices, the 1 ethernet device, and the PCI Simple communications device. After uninstalling them, still in safe mode, I tried executing the drivers for the ethernet card and pretty much received the same issue.

    - When I activate the driver, I am led to the installation screen, and told to select the driver to install.
    -Below in the list, I see a driver avaiable, but in ( ) next to it are the words: Not Needed (No Device to update present).
    - This leads me to beleive that these might be the wrong drivers for the device, so I try a different driver. The video driver this time.
    - This driver takes a little longer to install, but it's all automatic, nothing to select, except to hit the "FINISHED" button at the end. When this occurs, the OS prompts for a restart, I do this, and go the Device Manager, and all four "?" still remain.
    - To add a further twist, I have an ATI x1300pro inside the machine. I've tried using the device driver disk with that device, and I'm told that the ATI software cannot find the Video Driver.

    I'm beginning to feel like I'm chasing my tail.

  • susannej Jan 01, 2009

    Bat1956: Good call. It says that it's the wrong driver for the system. Since it's directly from Sony's website for this machine, I'm puzzled. Thoughts on how I can figure out which driver I need and where to hunt it down on the web?

    Kiran_G4E:Sadly, the OS has been reinstalled a total of three times now, same problem each time. I keep playing with other drivers because the ones provided apparently aren't sufficient!

  • susannej Jan 01, 2009

    Bat1956: Sadly, no ... we do not have the original system disk. Sony will sell us one for about $25, which we'll get in about 2 weeks ... doesn't really seem helpful to fixing the problem in a useful time frame & getting back online.

  • susannej Jan 01, 2009

    Bat: It was purchased in Oct 2006. The ethernet card is original to the machine. We have an old ethernet card in an abandoned machine & are thinking about scavenging it! We'll try the BIOS idea you suggested, then I think it's time to take a break for lunch before tempers fray further. :) Thanks again for all of your help, on a holiday, to boot! (pun intended)

  • susannej Jan 01, 2009

    Update: We found a different CD with ATI drivers on it (looks to be more current). The video cards are now not shown in the "other devices" category with yellow question marks...we're trying to reinstall from that disk, now. Weird! Now rebooting the computer ... Device Manager now shows video controllers are fixed & useable. Sweet. Now we just have to tackle the Ethernet issue.

  • susannej Jan 01, 2009

    We've also found that there is no system disk included with this machine (see here), and since the machine's already been reformatted, I am assuming we can no longer do what is directed by Sony's website.

  • susannej Jan 01, 2009

    Bat1956: I just checked My Computer, which shows that the re-install wiped out the entire drive - only a C: drive remains. Thanks for the hint on where to look!

  • susannej Jan 01, 2009

    It's fixed!!! Thank you for all of your help. We were able to do some digging & get some additional drivers that DID work with the machine. Thank you both!

Was this all working just fine prior to reinstalling the system on the computer. I want to first rule out any hardware connection problem. When you check the ethernet adaptor in the device manager, does any punctuation mark appear next to it to indicate a driver problem? if not, your problem is not driver -related, but rather settings. If the LAN connection appears in the manage connections or the connection wizard, you may only need to enter the correct settings to make this work. Make sure TCP/IP is enabled for the device, and that DHCP is enabled in the TCP/IP settings. The exception to this is if the modem does not assign an address by DHCP but is instead set for only a static address. If that be the case, you will need to enter a static IP address in the TCP/IP settings. In that case, look for a number on the modem in a xxx.xxx.x format, enter the number in the TCP/IP static IP address but adding 10. If the address is static, you will also need to enter a default gateway, which your ISP should have provided to you, along with the static address

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!.

    Since it seems to be a driver problem, perhaps you should install the drivers while you are in safe mode. To start in safe mode, reboot the computer, Press and hold "F-8" before the windows XP startup appears, you should get a menu, select "safe mode with networking" and allow windows to boot. You should be able to update the drivers in the device manager. Be sure you update from the correct directory. The directory must contain the files you got from Sony. You did copy the files to a known directory, and you unzipped the files to become a folder?

    "I'm beginning to feel like I'm chasing my tail."
    I know the feeling. I still have to deal with a couple of windows machines. You said the files are on your desktop, and that they are executables. If you move the files to the C:\ drive and execute them from there will they then install?


  • Bruce Volkers
    Bruce Volkers Jan 01, 2009

    I thought of one more thing....
    You obviously have the original system disk right? Don't you also have a Sony Drivers disk? That should auto-install the original drivers for you. (excepting maybe the ATI card) Once installed and you get the machine online, you can update the drivers to the most recent at the Sony support site. Then update windows, or enable automatic update, allowing that to run overnight.

    How old is this machine? Could the ethernet card have been replaced at some point? If so it came with it's own disk. Possible? Another idea is to buy another ethernet card with a disk.
    You also mention "BIOS". In the event that there arose a hardware conflict at that level, you might try entering "setup" at boot to enter the BIOS (typically the "delete" key) look for an item at the bottom of the screen to say something like "load defaults" indicating an "F" key to do so. Load the defaults, save and exit. See if that helps.

    " I am assuming we can no longer do what is directed by Sony's website."
    Depends on whether the re-install wiped out the entire drive or left the "D" partition intact. Look in "My Computer" for a D:\ disk with a directory. If the drive and directory are still intact, you may be able to download and re-install the application to make the backup disks.

I cant get my gateway 7320gz computer to get on line after reinstalling installing windows xp on it to get the drivers...


Sounds like the drivers for the network card are not present...

Grab a flash drive and the model number of your PC. Go to another internet connected computer and download the ethernet (and wireless if that's what you need) drivers frome here to the flash drive. Go back to your PC and install from the flash drive.

Ethernet controller and USB are missing on XP


Yes, the device-drivers can be downloaded from the Internet, to one computer, and then burned onto a CD-writable, or written to a USB memory-stick, and then the files can be physically moved to the other computer.

But, "which" device-drivers is completely dependent on which computer that you have. Some motherboards have "integrated" network-adapters and "integrated" USB-ports.

Easiest solution is to take an add-in PCI network-adapter card, and install it, and connect the Ethernet cable to its socket.
Hopefully, Windows will recognize that card, and automatically load the correct device-drivers from the C: drive, i.e., without Internet access.
Or, if you buy an add-in card, it may come with a CD-ROM that contains the device-driver.

Once the device-drivers have been installed, you will have Internet connectivity. Access: http://WindowsUpdate.Microsoft.com
and click "Custom" scan, and then click "Optional Hardware".
Windows Update should find the device-drivers for your motherboard, and install them. Then, you can remove the add-in card, and connect the Ethernet cable to the "on-mother-board" network socket.

Hitachi Desktop "Flora 370W" with Windows XP (8 months old) - LOST the Hitachi CD with hardware drivers & Windows XP doesn't recognize devices (i.e., Ethernet card). Thanks, P. Towle


Youll need a friends computer with internet access and a flash drive for this mission. Head to hitachi's website and look up the model of your machine. Download to the flash drive at least the ethernet and/or modem driver to your machine. You can either use these two drivers to get your machine online or you can download all of your drivers. If your model has multiple device drivers for each category, youll need a program called Everest. It will identify all of your hardware in your machine.

Ethernet not working after format and xp reinstall


Right-click the My Computer icon and select Manage, then go to the Device Manager in the list on the left and find the Network Adapter from the list on the right, right-click Network Adapter and select Uninstall. When you reboot, XP should find the Adapter and reinstall it automatically. Another reboot may be required.

If it still will not connect, go to the NIC Manufacturer's website and download the driver to removable media. The Driver Update option can be accessed in the Device Manager, but this time select Properties when you right-click the Network Adapter, and go to the Driver tab.

My monitor is stuck in the lowest resolution


Distorted video after increasing the resolution in Windows. The resolution has been set higher than what is supported by the monitor, ... we recommend 640 x 480 with 256 colors or the lowest available setting.
Computer always boots into Windows safe mode. When booting into safe mode, the lowest settings are used, including your video card. This means that the resolution is 640x480, 16 colors when in safe mode.
