Hi Grantowitz,
Thank you for using Microsoft Windows Forum.
a) Did you make any changes to your computer? (i,e downloaded and installed any mailicious softwares)
b) How are you trying to type on Games?
c) What kind of games are you trying to play?
Check if the computer is updated with all the latest Windows 7 compatible drivers
It is not a Windows 7 bug. It could be a virus that is bothering you.
If you have an anti-virus software run a scan from your anti-virus software and flush out the viruses.
