Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this

Redline in middle of the screen

sounds to me the screen is damaged, if youve owned that laptop for 4 months id suggest you return it for warranty service. before you do make sure to take a picture of the screen itself with every test youve done
