So I just bought a new graphics card (AMD radeon r7 240) and installed on my computer,but when I played a game it suddenly lags and after a few seconds a blue screen appears and it automatically restarts.

This only happen when I play a game that requires a mouse,because it doesn't happen when I play NBA.Please help me,what should I do?

OS:Windows 10
GPU:AMD Radeon R7 240
CPU:A 2.8ghz single core processor -_-
RAM:6gb
Motherboard:Gigabyte Ga-78lmt-s2p
Power Supply:750w
 

"Your PC ran into a problem and needs to restart".
That's what I remember,but it doesn't have an error code or something.

 


Maybe that is the problem,but i can play far cry 2 and Spider-Man WoS fine before installing my graphics card.
