Just after 3 weeks of use my brand new Lenovo Ideapad Z370 with Intel core i5-2410 with 8GB of Ram started giving me display problems and blue screens. This happened several time in last few days. Then yesterday screen went completely dead and never recovered.

This is how the flickering looked like just before it went completely dead:

Unfortunately Lenovo has only 14 days of DOA period causing me to wait for the reseller to send the laptop to Lenovo for repair.
