I have a Gateway laptop (model W340UI), it was running with Windows Vista then I converted to Windows XP. I was able to get Ethernet working but I am having problem with audio (no audio from speakers or headphone). I tried all over the internet but I found nothing. I checked the Device Manager seeing: ''PCI Controller'' with yellow question mark...Please direct me where to get this PCI controller or audio Codec...for free.

Do you have windows XP or Vista? In Vista, First try uninstalling the Ethernet adapter and rebooting the machine. The Vista OS should ID the hardware and apply the generic driver, if not run Windows Updates, make sure your windows updates are up-to-date. You can find the XP and Vista drivers here, select your OS: http://esupport.sony.com/US/p/model-home.pl?mdl=PCGTR3AP1&template_id=1&region_id=1&tab=download#/downloadTab

Hi There,

Go to this thread. Alot of people worked hard to put it together. I believe the Audio Driver a ways down the page highlighted in red will work on your machine.

I spent a long time tracking this down for you so NO "unhelpful" marks, please.

You can download the drivers for your model Gateway laptop from this

When you wriggle the plug in the power socket on the laptop and the charge LED flashes and in the right position it charges, this indicates that the power socket is faulty or there is a dry solder joint on the motherboard where this power socket is attached.
To get at the power socket will require dismantling the laptop completely. A computer repair shop can do the repair, I suggest you get a quote first.

this is a gateway site for drivers see if that helps...

From a computer that has internet access, download the appropriate ethernet driver for your network card from the link above. As for the recovery disk, you'll have to contact Gateway for a replacement disk.
