Alright, so I had reinstalled windows, and installed all my games all over again, and drivers after getting my new hard drive. I start playing games like Assetto Corsa and The Crew with my Logitech G27. I'm enjoying playing and randomly my computer turns off and my fans and everything are still on. It takes a couple seconds and then my whole computer turns off. I turn my computer back on and I have no blue screen. I went into event viewer and I got an error code 6008 for my computer randomly shutting down. I'm not sure what happened, and it keeps happening around 5 minutes into playing. I'm pretty sure it's not overheating because I stuck my hand behind the exhaust fan and i'm getting cool air when it randomly shuts down. My GPU and CPU can handle the games, so I have no clue what is going on. Anything helps!
