WINDOW 7 DRIVERS

[AVTAR SINGH]

I USED WINDOW XP ON MY PC. LAST SUNDAY I GOT A CD OF WINDOW 7 FROM MY FRIEND AND I INSTALL ON MY PC AND ITS WORKS FINE I GOT NO PROBLEM
BUT MY REAL PROBLEM IS THAT FIRST WHEN I FORMAT MY WINDOW XP AND REINSTALLED WINDOW XP, I ALSO INSTALLED DRIVERS OF WINDOW XP, AUDIO DEVICE DOES NOT WORKS WITHOUT DRIVERS INSTALLED.
BUT IN WINDOW 7 AUDIO VIDEO DEVICE WORKS PROPERLY WITHOUT INSTALLING ANY DRIVERS. I ASK TO MY FRIEND WHO GIVE ME WINDOW 7, HE SAID DRIVERS R IN BUILT IN WINDOW 7. NO NEED TO INSTALL.

PLZ HELP ME, FIRST WAT IS PURPOSE OF DRIVERS ? IS IT ONLY FOR AUDIO VIDEO DEVICES ?

SECOND, I HAVE TO INSTALLED DRIVERS OR NOT IF YES. DID I INSTALL WINDOW XP DRIVERS I HAVE ONLY THAT DRIVERS

1) I'm guessing you have an illegal installation of Windows 7, depending on exactly what your friend gave you.

2) It's very possible your system is not designed for Windows 7. You need to check the website of your computer (and various hardware) manufacturers for the correct drivers.

3) Please do not use ALL CAPS. It is the equivalent of SHOUTING on the web. Thank you.

The question is kinda hard to comprehend, especially because of all the caps.
15 seconds on Google got me this definition:

Definition: A driver is a small piece of software that tells the operating system and other software how to communicate with a piece of hardware.

Drivers let the OS (Windows and such) communicate with hardware. For example, Windows usually doesn't know how to use the graphics card in the beginning, but drivers teach Windows how to use the graphics card.
Windows will keep drivers if you upgrade Windows (as opposed to 100% formatting the hard drive and reinstalling Windows.)
Drivers can be available for almost any piece of hardware; some are auto-installing drivers (USB drives, etc) and some require manual downloads or installs (Graphics cards, etc).
If Windows XP was preinstalled on the hard drive of your computer, it originally had all drivers.
You should check by going to Windows Device Manager (Start>Right click Computer>Manage>Device Manager) and check to make sure all drivers are installed. If not, you should manually install them.

1. As Allan stated your copy of Windows 7 sounds dodgy.
2. If its all working, the answer is NO don't install drivers.
3. Drivers are required for every part of the computer, however Windows 7 tends to have much better out-of-the-box driver support than previous Windows Editions.

[immental1200]

Do speakers work fine?
Is it just headphones?

If so swap the speaker port, test the headphones elsewhere and then reply on here.

Look in device manager. If there are any yellow or red symbols then you need to install those drivers. You also need to install the chipset driver.

[AVTAR SINGH]
