Need assistance with drivers on Dell Vostro 3550
I am installing Windows 7 Home Premium x64 on a new hard disk drive on a Dell Vostro 3550 laptop. I found this thread which is similar to my problem, but I am still confused about the driver installation.
When I use the service tag to bring up the drivers available for download, there are no chipset drivers included. When I look at all the drivers available for the Vostro 3550, as mentioned in the referenced thread, I find four drivers but it is not clear which one/ones I should install.
1. Wistron USB 3.0 Host Controller Driver
2. Intel HM67 Express Chipset Family Driver
3. Intel Management Engine Interface Driver
4. Realtek RTS5138 Card Reader Driver
I have the following issues in Device Manager, all under Other devices, and all with yellow !:
Ethernet Controller
Network Controller
PCI Simple Communications Controller
SM Bus Controller
Universal Serial Bus (USB) Controller
Unknown device
Unknown device
I have one of three USB ports working. I have no network connectivity.
So far, I have tried installing from Dell downloads these drivers in the following order:
Intel Centrino Wireless-N 1030/Advanced-N 6230 Bluetooth Adapter Driver
Intel HD Graphics 3000 Driver
The Centrino Wireless-N driver did install but did not give me wireless access.
The Graphics driver did install and correct the video resolution as expected.
I have been reading that I first need to install chipset drivers, so I have the following questions:
Which of the four drivers should I install?
Do I need to uninstall the Centrino Wireless-N driver before?
How can I resolve the other issues in device manager that do not seem to have corresponding drivers?
Thanks.
