First of all, it's nothing to do with my PC hardware and only happens with MTA. I have an i7, GTX 760 and 16GB RAM. GTA IV, Battlefield 4, crysis 3 etc works fine after hours of gaming.
So it's been happening only on MTA for the last 1-2 months. I play for a while or even just get to the log in screen on the server i play (CIT) and my PC shuts down randomly! No BSOD, ive tried re-installing MTA and it still doesn't work, I have you wait some hours in order to use the PC again because it will not turn on from the power button.
Someone help please
