A few obvious things:1. The speakers are not plugged into the correct socket (usually the green coded one)2. The onboard sound is not enabled in the BIOS (the part that you press DEL to enter when you first turn your PC on)3. The incorrect drivers are installed4. There is a problem with the motherboard/speakers
With a CD
CD
No matter what motherboard you have, it does not have onboard graphics. Only certain processors have built-in graphics.
Onboard USB are USB ports built into the motherboard.
If you can identify the components on the board, such as the chipset, onboard graphics, and LAN, you can download generic drivers from the manufacturer of these parts that should work.
He's unlikely to read this. If you want software just find out what the model of your sound card is and do a google search for the drivers. Manufacturer's website is usually best. If it's an onboard sound card you'll need the audio drivers that are designed for that motherboard.
The onboard video
The Intel Pentium D 2.8Ghz has no video output and therefore does not need video drivers. It must be plugged into a motherboard first and even that is not certain to work. There must be a video card either onboard the motherboard or plugged into an expansion slot first.
IF YOUR COMPUTER IS HAVING A MOTHERBOARD WITH ONBOARD GRAPHICS THEN YOU CAN SIMPLY INCREASE THE AMOUNT OF V MEMORY USUALLY 128,256,512.IF YOU HAVE A GRAPHICS CARD THEN onboard graphics shouldn't be turned on as it may cause conflicts.If you want more memory on a video card you will have to upgrade to a new card with more memory..sorry there's no other option for this.
1. If the onboard VGA fails, you buy a new motherboard, but if the AGP video card fails you buy a new video card. 2. You can select any video features you want to pay for if you use the AGP video card, but you're stuck with whatever your motherboard has if you use the onboard card. 3. Onboard video cards are typically quite basic. 4. It must be faster and better than onboard vga.
It is a chip onboard a device that allows for firmware to be updated or settings to be changed like a computer motherboard's BIOS or a router to allow it to fix bugs/errors, add hardware compatability and features, etc.
Most motherboards will allow you to use both the onboard graphics as well as an add-in card at the same time. Even if they do not, an add-in card simply disables the onboard one.
