This issues just started to happen recently. For games Like CS:GO and Heavenly benchmark my system will power off, all fans and HDDs stop running, I have to turn off the PSU to get it to come back on. Would this be related to a PSU issue or a motherboard issue?

The specs are here.
- BioStar TA970
- AMD Phenom 2 8530
- Nvidia 660TI
- PSU Corsair 750W
- 12GB Of G-Skill

Not sure what else is needed. I just turn it back on now and it "Seems" to be fine. Under hours or playing and never turning it off, the North Bridge Does get up to 67c and sometimes 80c+ Im thinking this may have something to do with it but im not sure, just played 2 hours without issues.

I'm thinking the same thing, sounds like a power issue, might need a new power supply if it happens again. also I had a motherboard that caused this once also. I'd say chances are 85% psu , 14% chance it's motherboard, 1% something else. With pc's there's always the 1% chance it's something completely unexpected lol....

crap, just noticed u said ur mother board temp was climbing passed 80c
this is too high! you need to position a fan to cool the boards bridge chip, or get more air moving thru the case!
Regardless of what any manufacture specs say, no chip should ever exceed 80c, With any chip, from any manufacturers 80c is the unwritten limit! at around 80c weird stuff starts to happen inside the chip. electrons start jumping in ways they normally would not do inside a chip, be it a CPU, a single transistor, capacitor, ect... and around 90c perminant damage starts to occur. also note, that some chips have even lower limits before damage occurs depending on complexity, and quality. but no semiconductor like 80c and up....
