My hardware doesn’t respond under Win xp

I can’t use none of my devices – such as sound, keyboard, touchpad and from time to time my usb mouse dies.
I’ve re-installed my Win xp several times, but even during the installation the devices didn’t work. I tried a different winxp – same thing.
In safe mode everything’s fine, but even formatiing C: doesn’t work.
Need help, because next step is throwing my laptop out the window.
Thanks.
