Windows 7 problems with keyboard and mouse during gaming

[Sephy23]

Whenever I am in various games on windows 7 my keyboard acts up, sometimes it doesn't work or sometimes it gets stuck in one direction.. When I exit games my drag and drop capabilities goes out the window sometimes.. It only happens on Windows 7, when I use XP{dual boot} everything runs fine.. Anyone know what the problem could be? Thanks for any help..

I also meant to say I tried a different keyboard other than my g15 and the same thing occurred..

Samething still happening, only on windows 7 too.. Just playing a game and when I hit a certain direction it gets stuck in that direction or does nothing at all.. Only does this on windows 7 and it happens with most games..

Ok, well it isn't just Windows 7, it happened on Vista 64x also.. Maybe I have having some sorta problem on 64 bit OS's only
