This isn't a keyboard problem so much. This problem persists even in the BIOS and on a second multi-boot OS.
Please help me. This problem has developed on several computers I have owned and I can't fix it. The keyboard and mouse behave as if the ctrl key is permanently depressed but it's not. I can't type without ctrl-key-functions executing and when I use the mouse it mutli-selects files and does other things I would expect as if I were holding the ctrl key. It's completely unusable. There are times when it will behave properly for a couple of seconds but this rarely happens and is unpredictable.
I have tried multiple keyboards with different connectors. I am using Windows 7 64bit but I have experienced the same problem with computers running XP and Vista in the past. My thoughts are that perhaps an external hard drive or other external device is physically damaging the computer. Or this may be a virus that I have transferred across multiple computers. The day before my problem started I plugged in a new WD My Book Essential 1TB external harddrive it forced me to run it's software before it would even appear as a harddrive on my computer. It might have caused the problem. But there were some Windows updates and a Firefox update too.
