crashing on pc worse in morning (GMT)

my game crashes to desktop with no error, always seems worse in the morning UK time, as i get into the evening it seems to become more stable, like its something to do with the servers being busier? in the mornings i can barely play for 1 minute before crashing, when i get home around 5-6pm i can play for 5-10 minutes before crashing and then around 8-9pm i can play fine
