I dont have the driver for intel celeron 331 865G-MB

For hardware/driver detection you need software like driver magician / driver guide / driver detective .

these softwares can detect your unknown hardware and can search latest drivers

you can see here how these works http://www.drivermagician.com/

You can try this small application (http://www.cpuid.com/download/cpuz_150.zip), just unzip & run it and you'll see the details and the brand/model name of your CPU, motherboard and memory. And also for other hardwares (like graphics accelerator, network cards, ...) you can install and try this application (http://www.cpuid.com/download/pcw2008_v1871.exe) to get more detailed information about your computer's hardware. These applications are very simple and easy to use, I think it won't take too much time to get the knowledge of your computer's hardware. After this step, you can go online and check the website of the each hardware's manufacturer's for their latest driver according to your operating system. I hope this helps.
