Hey brother Anul,
If you've played before but stopped playing after sometime then there is a problem from your system, I think your problem is related to your graphics.
Try going to your system manager by right clicking on My computer > properties > Device manager then find video controller or graphic driver or something relevant to graphics, if you find some yellow exclamation mark on it, right click on it and uninstall it or click or update drivers, then locate the driver for your card Intel or nVidia and install it.
I hope it'll work for you, have a fun gaming.
