Some process/service/driver repeatedly presses F5
I have the strangest problem that started 2 days ago (Windows7, 64bit). SOMETHING causes my F5 key to be constantly pressed. Rebooting helps, but only for a while, it keeps coming back to that.
So far I've tried to disconnect and reconnect the keyboard (physically), however, disconnecting the keyboard doesn't actually do anything. Reconnecting it back again, causes the F5-pressing to stop, but not for very long (seconds/minutes).
I'd really like to avoid a binary search for the programs (process closing/keyboard switching/etc) before I can, at the very least, identify the source of the keypress. Is there an application that can show me what is causing a key press? E.g is it the keyboard driver, or some process that executes SendKey repeatedly for reasons unknown.
P.S FYI, having F5 causes the strangest side effects. Task Manager refreshes very very quickly (as F5 is refresh), the desktop is constantly flickering and all the browsers stop working as they keep trying to refresh. I was lucky to find out what the heck is happening only because I started notepad and saw that current date/time started to appear constantly. If not that, I'd still be wondering.
P.S.S Another tidbit that might turn useful for anyone experiencing a similar issue: The problem described, turned my workstation effectively unworkable, as you can understand from the symptoms described above, the best solution I found so far is using AutoHotKey with the following script:
!F5:: +F5:: ^F5:: F5:: return
Which effectively disabled F5 key system-wide. It works great and almost without any CPU loss, still, of course, I have to get the issue solved.
