My problem appeared during a game of overwatch. What happened is everything went dark on the screen and then immediately started showing squared green colors on the screen. After 10 seconds or so...my game minimizes-to-desktop. My game is still open but I cannot see anything appearing when trying to maximize it. I tried playing games like TF2 and CS:GO but the problem never appeared. I tried games that are higher demand of performance and they seem to get the issue appearing. None of them crashes my PC but some of the games crashes-to-desktop (doesn't minimize itself like overwatch). Which means this problem appears only on Games that hog a lot of power. I had a similar issue like this a year ago when these Artifacts appeared during booting but it is extremely rare to happen. I thought it was just a simple hiccup. I tried to investigate this issue so here is what I know so far: - My laptop has not experienced any artifacts during regular use. - Artifacts can usually be the cause of Overclocking from what I read, however I never overclocked my system at all. - I had few cases where my PC would immediately shut off without warning like a power failure. This problem was solved in another thread I created: http://forum.notebookreview.com/threads/figure-out-the-issue-of-my-computer.830207/ - I am getting fan noise from the CPU side of my Laptop. I am getting a fan replacement but its taking a while to get there. (possibly related to the issue?) - Temperature is around 70-87 degrees Celsius on some demanding games. - My Computer's Battery doesn't fully charge anymore. My AC Adapter's cable is a bit damaged by the cable but it is still able to charge. I tried playing games with battery/AC adapter and Adapter Only. The issues appears on both. I haven't tried battery only. What might be the cause of my issues? [The Laptop is a Sager NP8173] Side-note: This problem is making me nervous. I hope it isn't the GPU dying again. This time I have no warranty, and Sager told me that these following issues can cost me more than $1500 which is way pricier than my Laptop.
