I have been having this issue for a while. Every time I run a game, and sometimes when i'm browsing the Internet, my computer suddenly crashes and I have to force shut down the machine. This crash can happen 5-60 mins into playing but it almost always happens. I was having this issue in Windows 10 so I downgraded to Windows 8 with a factory reset but the problem persists. I have tried many fixes from the internet such as disabling link state power management and re installing drivers. If anyone can help me out with this it would be greatly appreciated. Thank you.
