Newest official released Forceware 91.31 are solid drivers however with an annoying bug thus, for non- SLI users every time you reboot it pops -up a Balloon message reminding you not to be in SLI mode. Also even if you have disabled the nvidia display Taskbar icon from the "Tools" settings page (must switch to classic Control Panel), taskbar icon is enabled again at next boot! Just run "sliballoonTB_fix.reg" (included in the zip file) to fix both bugs. Also, in case you will in the future do SLI. Run at that time "sliballoonTB_unfix.reg" (also included in the zip file) to undo the previous fix or you will not be able to see the SLI Configuration panel. Download fix in zip format from here: users.otenet.gr/~markoul/sliballoonTB.zip enjoy Note: There is another fix floating on the net fixing only the SLI Balloon bug and not the Taskbar icon bug... However, it disables all Balloon Messages in general coming from your Graphics driver such us "high GPU Temperature Notification"...
