I have the same issue as well. It looks like its a USB issue for me. My mouse, Keyboard and speed pad are all USB. While im playing a game, its as if the keyboards keys all get remapped and the mouse goes nuts. When I left click the mouse once in a open dirctory, it picks 3-5 things and not 1. Looking around here for the past while, I see others with a similar USB issue. Looks like it might be a issue with the last BIOS update.
Anyone else have the same issue?
Has anyone been able to find a fix for this?
