i just had to move to my laptop because my keyboard just went crazy. i have no idea what HAPPENED, i was watching a movie on youtube and i went to search something and nothing happened. i noticed the num lock light went off so i tried to turn it on and nothing happened. i unplugged the keyboard and plugged it back in but nothing happened. i restarted my computer and it stopped, saying that it couldn't DETECT a keyboard. so i went in the back plugged it back in and it worked...for like 2 seconds, just enough to press f1. of COURSE i get back on youtube and the keyboard doesn't work anymore. i took my brother's keyboard from his computer and it didn't work either. briefly, when i began plugging it in all 3 lights flickered, then went out and nothing worked. any help or ADVICE would be much APPRECIATED, currently my computer is just off.Are you plugging and unplugging while the machine is running? Bad idea.

You probably have a motherboard heading south and the PS2 port was the first thing to go.
