Hello everyone, I an not to sure what is going on with my system. I have completely upgraded my system. the build that i currently have is, An Asrock Z97 aniversery motherboard with the latest BIOS' Intel I5-4440 3.1Ghz, APower AK series 850 Watt PSU, 250 GB SSD drive, Nvidia GeForce GTX 950 GPU, Corsiar h100 liquid cooled CPU cooler,and 24 GBs of ram, and this might be the problem but who knows it is hooked to my 52" 4k 3D TV.

Ok so now that you have an idea of what i am working with i will let you know what my issue is. It only dose it when i am playing TC's The Division. my computer will all of a sudden restart. Now my question is what is causing this to happen the GPU over heating, and if so what can i do about it, and if not what is your opinion. there is no message for not suhtting down improperaly and 1 time while i was watching netflix i got a green screen and PC froze how can i fix this problem so i can get back to playint TC's The Division, Please And thank you for your time

Respectfully
Will ( williamMs39426)

Well, for one thing, A Power is a no-name brand, so their unit is guaranteed to be junk. What is happening could be a variety of things, but most likely it uses bad capacitors that are already failing, causing the freezes, and this could also be causing things like over voltage protection to kick in at times. Not just the capacitors, but there could be numerous things inside failing because of poor build quality.

As for the shut downs, it might be a protection kicking in to save your system's butt.

Poorer quality PSU's tend to get a bit 'wobbly' before their rated loads, especially at temperature, and often (for the poor units) as much as 50% below rated load. So what could be happening is a voltage dip (if you are lucky) as you try to draw more than the PSU can cope with, the worst case which obviously hasn't happened yet, is that something fails, some times a capacitor, sometimes a part of the rectifying circuit and this then causes a spike in voltage, or simply burns out a part of the PSU.

You are obviously having a soft failure, as you can reboot, however please get this fixed, as it could change to another failure mode, or it could interrupt a disk write operation and cause some file or disk corruption.

More than likely, you have power supply issues such as poor regulation and/or leaking or bulging electrolytic capacitors. Take a look at the photos at "Capacitor Plague" and note the tops are scored so they can split open and vent. Try obtaining or borrowing another power supply and do the substitution test. If erratic operation stops, purchase a new PSU. Check listings for top rated units and avoid buying junk.

My preference are ones having no 110/220 input selector switch where a single input ranging between 105 and 250 volts, 50 or 60 cycle is utilized. The advantage is constant output even under brownout conditions. When demand is greater than supply, power companies have been known to reduce voltage. A quality power supply having a wide input range can easily compensate.
