[byakuren]

hello guys i have a one year old acer aspire 4740G notebook

recently my network adapter broadcom netlink gigabyte AR5B93 has stop working..so i tried to check the device manager and everything was fine except the

Intel (R) 5 Series /3400 Series Chipset Family PCI Express Root Port 2 - 3B44. it say This device cannot find enough free resources that it can use. (Code 12)

If you want to use this device, you will need to disable one of the other devices on this system.with a yellow warning sign..

how am i supposed to do with this,my Wifi adapter is totally disabled because of this,and when i check the adapter setting it says Network Cable Unplugged..

I try to reinstall the driver but its no use

It seems like you are facing a Code 12 issue on one of your system devices, specifically the Intel (R) 5 Series /3400 Series Chipset Family PCI Express Root Port 2 - 3B44, which is causing your Broadcom network adapter to stop working. This error indicates that the device cannot find enough free resources to operate correctly. Here are some steps you can take to try and resolve this issue: 1. Reboot Your Computer: Sometimes a simple reboot can resolve resource allocation issues. Restart your computer and check if the problem persists. 2. Check for Hardware Changes: Ensure that no new hardware has been added recently that might be conflicting with resources. 3. Update or Rollback Drivers: - Update Drivers: - Go to the Device Manager. - Right-click on the problematic device and select "Update driver." - Allow Windows to search for the latest driver software. - Rollback Drivers: - If updating the drivers doesn't help, you can try rolling back to a previous version. - In the Device Manager, right-click on the device and select "Properties." - Go to the "Driver" tab and select "Roll Back Driver" if available. 4. Disable and Re-enable Devices: - In the Device Manager, try disabling and re-enabling the problematic device to see if it helps resolve the resource conflict. - Right-click on the device and select "Disable device." Then right-click again and select "Enable device." 5. Check BIOS Settings: - Enter your computer's BIOS settings during startup (usually by pressing a key like F2 or Del). - Look for any settings related to resource allocation or conflicts and make sure they are set correctly. 6. Check for IRQ Conflicts: - In the Device Manager, go to View > Resources by connection to see if there are any conflicts, especially IRQ conflicts. - If there are conflicts, you may need to reconfigure devices to use different IRQs. 7. System Restore: - If the issue started recently, consider using System Restore to revert your system to a point where the issue was not present. If none of these steps resolve the issue, you may need to consult Acer support or a professional technician for further assistance. They can help diagnose the problem and provide a more specific solution tailored to your system configuration.
