Windows 7: Strange Keyboard "diagnostic mode"???

Okay before I get into it this started a while back
Since then an app I was trying trashed windows and I formatted same deal

So I really don't see any spyware keyloggers etc as being involved.
But just in case I have scanned clean with several scanners.

Here goes my attempt at an explanation...
Basically out of nowhere my laptops keyboard will go into what I'll describe as a diagnostic mode for lack of a better term.
Using my keyboard will simply repeat this pattern, "1234567890-=qwertyuiop[]asdfghjkl;'`\zxcvbnm,./-+\"

For example if I type "welcome" I would get "1234567".
If I come back a few minutes later and type it again I'd get "890-=qw"
Once I type enough to get to the end of that pattern it starts again.

However IE seems to be somehow involved but I can't tell you specifically how really. But in this case I launched a new IE window and it stopped.


I know it's not much to go on I've done my best to try and explain.
If anyone has any ideas I'd appreciate it.

Thanks,

It is suggested that problem can be a bad system file.
go to start>command prompt>right click>run as administrator, type
scf /scanow hit enter, it should repair bad files if any (hopefully) see will that solve your problem

Well after ages I think I actually solved it.
It was being caused by my email client "Zimbra", a company Yahoo bought.
I've been using it for over a year but they must have broke something in the last two versions.

I've killed the client and it's service so hopefully that's the last of this problem.

The application and it's service is based around java on the back end.
So that in turn could have been using IE on some level.
That would explain why playing with IE was fixing the problem.
