|NOTE that this site uses software that highlights certain words in the text so that they're blue and underlined. If a post is long enough to require scrolling down to see all of it, due to whatever bug or bugs, the highlighted words DO NOT move as you scroll down the text. |
When you have scrolled down and you see a blank space where it looks like text should be, hold your mouse cursor briefly over any blue highlighted and underlined word or words that are not in the right place to make them pop into the proper place in the text.
The software seems to only highlight and underline the first occurance of a word or words, in the entire Topic.
The mis-placed blue highlighted and underlined words can be in the post, or above or below the post.
As riider said...
"Drivers are always free, you just need to know where to look."
"I have a sony pcv-rs312v with xp home edition 2002 service pk 3.sony does not carry anything that old."
Why would you look at support for current models ?
You search for support for previous models.
If that's what you did, you didn't look very hard.
I found the following link in a few seconds...
I'm assuming you bought the computer in the US - if you didn't.....
- the info and drivers may be the same if you bought it in Canada
- if you bought it in some other country, tell us what country you bought it in .

Drivers & Software
"Where do you get main chipset drivers "
First - Motherboard - download and install the Intel 856 main chipset drivers
Also download and install....
Audio (Sound) - Realtek AC'97 Audio Device Driver
(Your audio adapter that's built into the mboard DOES NOT use SoundMax software !)
If you are still using the video adapter that's built into the mboard...
Video - Intel 82845G/82865G Graphics Controller Driver
(or you may be able to get a newer version on the Intel web site in the downloads for the desktop 865 chipset series.)
If you are still using the Sony monitor that came with the system
- Monitor Inf (Driver) - Sony Monitor Inf Utility
Network - RealTek RTL8139 Ethernet Controller Driver
If your network adapter that's built into the mboard already works, this may be a newer version that what is built into Windows.
Modem - Agere Systems AC'97 Modem Driver
That MAY be a combo dial-up modem / sound adapter, in which case it's a card in a slot, and it has both one or two telephone jacks and three (or more) 1/8" jacks for sound - that MAY have an ADI sound chipset that requires SoundMax drivers and software .
Installing all other downloads is optional.
You MAY get error messages, or a USB device may NOT work, if you are not plugging the device directly into a USB port on the back of the case...
Troubleshooting USB device problems including for flash drives, external drives, external memory card readers.
See Response 1:
For some desktop mboards you can have problems when an external hard drive is plugged into one of a pair of USB ports on the back of the case that are connected to the same USB controller, if there is another device plugged into the other USB port for the pair, because the pair can't actually supply 500 ma per port - they can only supply 500 ma in total. Usually those pairs of ports are one above the other, not beside each other. If you have two devices plugged into such a pair of ports, try plugging one of them in elsewhere on the back of the computer.
"Usb 2.0 i plug in a opt mouse wizard says no software"
As I said above...
"If the mboard has USB 2.0 controllers....
- they're backward compatible with USB 1.1 specs.
In most cases all available USB ports support both USB 1.1 and USB 2.0 specs.
(for the XP CD you used to install Windows, or you can do this later if it has no SP updates built into it all)
"- XP must have SP1 or later Windows updates embedded in it in order for XP to have the built in support for USB 2.0 controllers and devices."
In most cases the original software installation. or the XP CD you use to install just Windows, DOES NOT have SP3 Windows updates built into it - SP3 updates were installed in Windows later.
RIGHT click on My Computer - Properties - on the right side of the first screen you either see
- no mention of a Service Pack,
- or you'll see Service Pack 1 or higher.
If there's no mention of a Service Pack,
download and install this:
Windows XP Service Pack 1a Express Install (32-Bit) for End Users
"- the built in support for USB 2.0 controllers and devices is NOT installed in Windows until AFTER you have installed the main chipset drivers for your mboard.
If you get "nag" messages when you plug in certain devices such as USB flash drives and/or external hard drives along the lines of "This device would work better if it supported USB 2.0" or similar, and you KNOW your mboard supports USB 2.0 specs, install the main chipset drivers ! "
A corded mouse does NOT require USB 2.0 support, at least no corded mouse I've ever used has, in order for it to work.
If you searched for newer drivers, you were searching for newer generic drivers for a mouse that are built into Windows - Windows will not find newer drivers.
In some cases, you can download and install specific drivers / software for your mouse model so you have enhanced Mouse settings to choose from in Control Panel, but that's optional.
"If ANY of your USB ports don't work at all and you're sure they're Enabled in the bios Setup, then your mboard is damaged, or if you have a laptop or netbook computer, a small board that plugs into the mboard is damaged. "
"Where is bios settings"
You usually see a line while booting the computer "Press (a key) for bios Setup" or similar - if you see that line, press the stated key while the line is still on the screen to enter the bios.
If you change any settings in the bios, SAVE your changes before you exit the bios.
READ the screens to find out what certain keyboard keys do.
In most cases, a mouse of any kind does not work in the bios Setup.
Or - READ the manual for your specific model !
