Laptop pink screen problems

[Rob_1010]

I have asus rog G752vs laptop(non k version) : https/www.asus.com/in/ROG-Republic-Of-Gamers/ROG-G752VS/
Specs: i7 6700hq, gtx 1070,16gb ddr4 2400mhz ram, 1tb 7200rpm hdd , 17.3 inch FHd gsync screen. When I switch on the laptop from a power off state, I get pink color lines before the OS boots up. This happens all the times. Sometimes, in 1 out of 10, my laptop fails to load the OS even after 5 min. Just a black screen after asus rog logo. Then I need to hold the power button for 5 seconds, which will turn it off, then power it on once again. So am I having problems with Hdd or something else? I got the laptop from US. My friend got it for me. I am living in India. Will asus service center take this kind of laptops? Thanks

And I forgot to add, sometimes while playing cs go, the laptop abruptly freezes and I need to restart it. It does not happen while I play games like Ghost Recon Wildlands or PES 2017. (all setting are set to high at 1920 by 1080)
