I dont my mother board

Is this motherboard in a working computer, and is internet capable?
(One never assumes, as the person asking the question, may be using another computer to post the question)

If so, I suggest going to CPUID.com, and download CPU-Z. (It's free)
CPU-Z will tell you all about,

1.Mainboard, (Motherboard): Who makes it, what model number it is, what processor socket it has, what motherboard chipset it uses, what integrated audio, (Sound), what integrated graphics, (Video) (Unless it doesn't have integrated video, and relies on a graphics card), and so on.

2.Ram memory: How many ram slots it has, what ram slots are being used, what ram type it uses, what ram 'speed' it uses, and so on.

3.Processor: What processor is installed, who made it, and what model number, what the Front Side Bus is, (FSB), what the internal clock is, and so on.

Finding the motherboard manufacturers name, and the model number, you go online to the motherboard manufacturers website, go to Support, and type the model number in. This will take you to a Support page for that motherboard. There you will find a CPU Support List, (Processor), plus what the Maximum TOTAL Amount of ram is, and what the Maximum Amount for EACH ram slot is, plus a host of other info.

You can also try downloading Belarc Advisor.

If the motherboard is in your hand, look on the motherboard, and see if you can see the motherboard manufacturers name.
(Examples: Asus, AsRock, Chaintech, Gigabyte, Intel, MicroStar International Inc.,(MSI), ECS, Evga, PNY, PCchips, and so on.

Look for the model number on the motherboard. It may be in-between the expansion slots, near the edge of the motherboard, or in the middle.

If this is a motherboard that came out of an HP, or Compaq computer, things gets a little tougher. Post back here with the computer name and model number.
It's on the back of a desktop computer, right next to the Windows Product Key, or up on the side of the tower.

For a laptop it's on the bottom. It may be in a Service Tag.
