Since a few hours, I have been starting a game called Conqueror's Blade (MMO) and once it loads in with the character, my pc just restarts as if someone cut the power and put it back on. I checked and cleaned my RAMS. But then when I restarted its not reading my secondary hard disk. I have a primary SSD and a secondary Hybrid HDD. The hybrid drive is not showing anymore. Is this a PSU issue? Pls help!!!
