Go to the Microsoft website and download them? Search the internet for Keyboard/Monitor drivers of your make? It is hard to understand what you want, your english isn't all that great. ^^
If you don't know how to find your drivers, there are programs that will scan your computer for outdated drivers and update them for you. Radarsync is one, but it's not the best. Just be careful when using those types of programsand make sure you scan them for viruses/trojans and malware before installing them.
