So I have built my self a computer with these parts:
ASROCK Z87 PRO3 mother board
Nvidia geforce gtx 660 graphics card
intel i5-4670k processor
Windows 7 64 bit operating system
thermaltake 600w power supply
1tb hard drive
It continues to turn off when I play games that are more computer intensive such as Call of Duty Ghosts, Battlefield 4, and DayZ. I was hoping for some help. Any help would be appreciated. Thank you
