Hi guys,
I am having the same problem, i have tried everything that has been suggested on this thread and still no joy.
Even writing this post is a nightmare as it keeps loosing focus on the window!
I have wiped and formatted my drive and reinstalled windows 3 times trying to solve this, i have downloaded and made sure all my drivers are up to date, hoovered it out etc. everything i can think of and have read online, tested the memory disk check. i have just a few things on my comp, steam, left 4 dead 2, ESO (not played it just ready to play), tp link and advanced system care Google and opera. thats it. if i start left 4 dead i get as far as the menu then its minimised, if i play the same just keeps happening. if i type on here every so often the windows error sound happens and it has deselected the window and im no longer typing.
NIGHTMARE!.
Doe anyone have any other suggestions, i just want to enjoy playing some games on my pc this christams!
thanks
