Solved! lenovo edge black screen

[humzaejazali]

i was watching videos on my laptop when it suddenly switched off with blue screen of death it also showed up with weird colours after a couple of reboots like this : https/superuser.com/questions/569751/computer-suddenly-dies-screen-displays-weird-flickering-lines-then-restarts

now it comes up with a blank screen on built in display and external and after 10 seconds automatically powers off.

Sounds like your GPU, and possibly the motherboard itself, are the problem.
