Laptop: Lenovo y700-15ACZ. Fx-8800p. R9 M385x. 8 GB Ram. Win 10. About two weeks ago was my first random restart when turning on my laptop to play a game (rocket league). I let it restart, logged back in played again then restarted again 0.0 . Thought it would be thermal issues so I cleaned up a lot of the built up dust on the intake + fans, which of course did not help. Now fast forward a couple days I'm still getting restarts when doing something intensive but it now moved to browsing/downloading! Today was the first time my screen now freezes and dims, then all of a sudden goes black which I then have to restart in order to get it working again, the computer is on because I hear the music (which I purposely set too see if it would stop as well) so it hasn't restarted like normal. I fully resetted multiple times which did not help, as well as removing the battery and discharging it. I can't even open CMD in order to scan to see if anything is wrong (when I was able to open up cmd before the black screens the scan said nothing was wrong multiple times). I'm completely stuck ~.~, nor do I want to pay geeksquad or something since I'm only 15 with 50 bucks in my pocket (if you guys think necessary then I will consider). Most of my actions in order to fix it were clean uninstalling display drivers, hard resetting the laptop, cleaning out fans, and discharging battery. If you guys have seen similar issues (random restarts doing something intensive or black screens while opening a program like CMDor downloading a program like steam please let me know)
