Possible Attack?

So I am at home using my XP laptop wirelessly over my home network when suddenly everything goes down and none of my 3 computers can get to the net. My router and Modem are all lit up correctly. I rebooted everything, unplugged the router and modem, let it cool out for a few. rebooted, now my SuSe 9.0 Linux doesn't register neither the keyboard nor the mouse. When the system boots up the lights on the keyboard come on but once i make it to the login screen neither the keyboard nor the mouse function. Where should I begin to look? I have disconnected and reconnected the keyboard and mouse to no avail. Your help appreciated, and to top it all off I am leaving for the weekend at 4am. Thanks, JP
