I have a bit of problem when I start my game. Upon starting the game , the game freezes but when I press Alt + Tab , and check the background , it seems to work fine but when I enter the game . It again freezes but the screen changes from what it was before. I didn't had this issue 4 hours ago but now it started to occur frequently. Also , i can move around on pressing keys but it doesnt show up on my screen. Please help!
Processor - Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz 2.20 GHz
Ram - 8.00 GB
It has been fixed but I don't understand how the problem occurred , I had to take out my wireless port for my mouse (it was out of battery and not working) and after that it worked properly , I don't know what kind of error it brought to Core game but it might happen again.
