I'm very new here so I'll do my best to provide the info needed to answer this question.
The setup: Sony computer (sorry, not much more detail because the computer is at my office), I loaded a free trial game called Wedding Dash 2 from Big Fish Games. I have been a member at BFG for over a year with no previous incidents. When I started the game, a box popped up telling me to adjust my screen resolution. The current setting was 1024x7??. I changed it to ???x1024 as requested. When I pressed apply, the option to continue with or without a restart came up. I chose to continue without restart. I played the game and approx. an hour later the game screen turned black then immediately turned white.
I have tried everything I can think of to clear this problem. I finally disconnected all power, telephone and DSL lines. That is how I left it.
My boss is out of town until Monday so I need to get this fixed before she come back. We are a very small company with no IT department.
