Hell friend, I am a game lover. I am having a Dell machine which is running with windows 7 OS, other specification of the machine are like 5GB RAM, 456 GB hard drive, along with this NVIDIA high definition graphics driver, and compatible with the wireless network service. I basically use my machine for online gaming and start to play a new game, which is named as “DC Universe”, butt from last night there is a problem in my machine whenever I tried to play the game. What should I do? How to overcome from the problem?
