Here is the situation: Everyonce in a while when I get to the XP opening page where it asks for your password or who you want to log on as my keyboard will not type. If I unplug and plug it back in it will work. Today however I started up my computer and I got a "Keyboard error or no keyboard detected" message. I tried restarting and using different USB ports, nothing worked. So, I used a hair drier to blow out the inside (a fair amount of dust) and then I restarted. For some reason that worked and I could use my keyboard again. I don't think it was the dust, I think I got lucky and it decided to work again. Has anyone had this problem before or does anyone have some ideas to ensure this does not happen again?

Thanks in advance,
Kyle
