So for about 5 months now, my computer has been "randomly" minimizing my full screen programs and losing focus of my non full screen programs. It used to be random until I noticed that it happened at every 55th minute of the hour and every other 45th minute of the hour. I installed Razer Game Booster and that can block the 45th minute interruption, but the 55th minute interruption persists. I traced my installed programs back to around when this problem started and noticed that it was coincided with the installation of my printer software. I tried uninstalling all of the printer software, but I still had both interruptions. My brother also installed these programs on his desktop, which has the same problem (but I think he only has one interruption, not at the same time). I may not have done a full uninstall of the software, or it may be something else. I tried to put as much info as I can remember, but I'm sure there's more. Any help is appreciated - 5 months of playing LoL with this is slowly killing me.
