Hello and thank you for reading.
I have an issue when playing video games on my computer. I've played games like Fallout 4, Witcher 3, and Overwatch recently. Randomly, it seems that my computer will crash. It will be a random color, usually one that's on the screen (for example, looking at a forest scene in game, my screen will go green) with some darker randomly placed vertical lines. There is no error code box on the screen. The fans then seem to run really high and loud, and I can't do anything but shut the computer down (no CTRL-ALT-DEL); I've also looked for an error code reading on the motherboard, but nothing shows up on the display.
The crash only happens when playing video games, never when I am browsing. It also seems to happen randomly, as in I could play for five minutes or five hours.
I've rotated the computer so it has a clear unobstructed path for the fans, but that hasn't seemed to work either.
I've included my specs here: http://speccy.piriform.com/results/54w0lZ6uFssiAXy1uCrxoqx
Thank you for reading, if you could help me I would greatly appreciate it! Also I am new to this, so any walkthrough to any fix (or any other necessary information) would be immensely helpful Thank you!
