Hello. My PC keeps random alt-tabbing (or just goes to desktop) on its own for about a month now. I recently formated and changed keyboard so there is no issue in there. I close all programs and changed usb ports for the peripherals, still pc random alt tabs. I really need help this is getting on my nerves i cant play games i cant watch movies i can do nothing. Aprox. i get 10 random alt-tabs in 30 minutes. I even did a complete re-install of windows 7 since there was nothing really important and it continues to happen. I've made sure everything is updated and that there are no virus' or spyware, yet it still happens randomly and I'll alt+tab like crazy getting back to the game, but it switches back just as fast leaving me frustrated and wanting to break this computer.
OS: w7 64bit
cpu i5 4670k
16gb ram ddr3
gpu r9 380 4gb
mouse chroma deathadder
keyboard cm suppressor
no extra peripherals like camera and usb sticks
headset logitech g10 gaming
help!
