My pc screen turns red and my system reboots after playing about 30 mins of bf4 ?????? please help !

[ols1000]

i have:
amd fx 8350
amd msi hd 7770
gigabyte 78lmt-usb3
8gb ram

I don't think that it is due to my hardware not being good enough as i get 50 fps on high settings and i play at med/high.

i have noticed that my pc is quite loud but i think that that is due to the small fan blades.......skyrim runs fine at ultra and i have never had this problem with that game ???
what do i do to fix this ???
any help be be good.

Have you monitored your temperatures?

What kind of PSU do you have?

What PSU do you have? Also, try to check your temperature while running BF4.

The brand of the PSU?
Install programs such as http://www.cpuid.com/softwares/hwmonitor.html.

That is a very bad PSU. Your PSU is the reason, most likely.
