Hi Deposito. Your English is fine by the way,
You haven't said what type of keyboard and mouse you use. Are they wireless, or usb?
If wireless, see if new batteries make a difference. Make sure the wireless transmitter is plugged in properly.
If USB, plug the keyboard and mouse into different USB ports.
Otherwise, get another keyboard and mouse, (ask a friend if you don't have any spare ones), and try them.
My Windows is having a freeze problem after Welcome Screen. Let me explain better.
When I turn on my pc, my windowsxp works perfectly. But, after I restart my windows, my keyboard and my mouse stop work. I know that only the mouse and the keyboard freezes because the clock and the "hiding icons" features works perfectly. Then, I have to press the reset button on my CPU, and now my mouse and my keyboard are working. But... if I reboot again my computer, this freezing problem will appear again.

I have tried many things, reinstall mouse and keyboard, install new drivers for my motherboard, remove some programs, but I cannot fix this problem. Until this moment I really have no idea whats going on with my windows. And now Im calling my friends of CNet to help me, "giving me a light".
(Unfortunately I cannot remember since when I have this problem and then I cant have a clue why its happening.)
Thanks for sharing your attention and sorry for this "simple" english.
