ok so i just replaced the hard drive in my comp about a year ago and last week it started humming again! crap, time to buy a new one. but then tonight when i got home from work i found out tha some of the keys on my laptop have mysteriously stopped working. from what i can tell the fallowing keys on my laptop don't work: 0 (zero), p, -, =, [, ;, ', / all the other buttons o the keyboard seem to be working fine, but what would be causing just those buttons to go out? my wife said she ain't done nothing to it all day. i don't know what to think.
