A few days ago, I installed windows 7 home premium 7600. Ever since, my arrow keys do not work correctly. I do a lot of online game playing, for example, and I've discovered that I can no longer play almost any basic platform game on any site. The arrow keys simply no longer function correctly, and refuse to move a character in any direction. Sporadically the keys may "turn on" and work for a split second or two, but then either do not work at all or act as if they are being held solidly down in one direction (when they aren't). I believe this problem stems from installing Windows 7 because, number one, I have never had any problem remotely close to this prior to W7. (I was running Vista before.) Number two, my computer is very new (a little less than six months old.) If anyone could help me with this problem, I would greatly appreciate it.
