I had just booted up Rainbow Six Siege after buying it and my room was pretty warm to say the least. I had been on it for over an hour and a bit when my computer suddenly just died. The computer powered off but the monitors remained on. I did power cycles; unplugging and switching off at the wall and so on but nothing. I unplugged the computer and took it somewhere cooler to cool down and just tried it again but no power once more. No fan activity no lights just dead. Any suggestions?
