Uk keyboard driver.

I've recently reinstalled windows and most of my other software after my original hard drive died. I have managed to get most things working ok. However, the keyboard is in US style so
the @ button is now a "
and the GBpound sign is a #.

is there a driver available for a UK keyboard? or can i change the keys manually somehow? i have been unable to do either as yet and would be really grateful for any help or advice anyone has.

there are a couple more things if anyone would like to suggest; what is the best version of bios to run? i dont know what it was on originally but i upgraded to a32. this ran the system much hotter than i would like with the fan only starting at 50 celcius. so I downgraded back to a22 which seems to keep the temperature down to a healthier 37-9 celcius. I wonder if anyone has any suggestions (I am already monitoring with I8kfanGUI). and what should the screen resolution go up to? currently the maximum is 1024 x 768 pixels, but i thought it used to be more before, perhaps i have installed the wrong monitor or graphics card driver?

thanks in advance
