So I've been running my computer for about 2 days and after I pass the 3 hours in a row my computer shuts down and then doesn't start up for another hour. Now I think the issue is heat because the cpu is reaching 45 celsius while I'm playing and in Hardware Monitor it says the max temp for my cores in about 45 celsius, would that be the issue if so how can i fix that? Or is the issue a psu issue? My build: Asus GTX 770
Gigabyte Z87X UD4H
Intel i5 4670k
XFX 750 Watt Gold PSU
Corsair Vengence LP 8 GB 2133
Cooler Master Hyper 212 Evo (w/ extra fan)
