Hey Computer shutting down/screen turning to a solid color while sound is buzzing while playing graphic heavy games i have no problem with mobas. But if i lower graphics its working. Amd fx8350 , asus gtx 970 strix , asrock extreme 4 ,500w psu thermaltake , corsair h80i liquid processor cooler. Nothing is overheating processor 40-50degrees on load gpu 60 on load motherboard max 52 degrees all celsius.

To start with, sorry it took me so long to get back to this question... I was busy with a client machine.

I see two problems at work here.

1. Your power supply is suffering a slow and silent death as the power distribution systems just can't keep up with the amperage your system is drawing. This is made observable as the 12v voltage drops under high CPU load.

2. Your CPU cores are at an okay temperature, but your socket (it calls that "CPU") is getting rather warm, so your CPU is throttling back its performance to keep the socket from getting dangerously hot. This phenomenon is known as thermal throttling and it occurs when one of two possible situations are happening. The first possibility is that you have overclocked your CPU and...
Okay, I need you to start your computer up and just let it sit for five minutes. Then open Task Manager and let me know what all is running. This could be caused by a conflict between a program that's running in the background interfering with a game that you're playing.

Edit: I just realized how horrible the grammar is in my last sentence. Oh well, I'm sure you got what I meant by it

I reinstalled windows and i had the problem before i had the gtx 970 but back than its was only turning to solid color and sound buzzing never shutting down and occuring maybe few times a week after playing for a very long time 8hours+, now its like i run witcher play for 10 mins and it shuts down
 
Please download and install AIDA64 extreme. You'll need to use the first green download link, the one that's 15.88MB in size. Install it, then go under the Tools menu on the menu bar at the top of the program window and select System Stability Test. Stress everything except for the hard drives. After thirty minutes, stop the test and post the average, minimum and maximum voltages to the core, as well as the 3.3v, 5v and 12v rails. This will tell us if it's voltage instabilities from the power supply that's causing the problem.

Your CPU cores are at an okay temperature, but your socket (it calls that "CPU") is getting rather warm, so your CPU is throttling back its performance to keep the socket from getting dangerously hot. This phenomenon is known as thermal throttling and it occurs when one of two possible situations are happening. The first possibility is that you have overclocked your CPU and it's simply running at too high of a power limit. The second possibility is that your CPU cooler is inadequate. If you have not set overclock settings, then this is simply a cooling issue.

Here is another thing I need to add. Your 970 is (hopefully) hooked up to the power supply via either 6-pin or 8-pin power connector(s) (I'm counting a 6+2 pin power connector as an 8-pin connector). Well those connectors run at 12 volts. What we just observed is that your power supply is lowering the voltage delivery on the 12v rail when running at a high load. The drop in voltage would cause your 970 to destabilize since it draws its power from the 12v rail.

Two things need done here: First, get a new power supply, I will suggest a few below. Second, get a new CPU cooler. If you don't know how to put a CPU cooler on properly, there's a wonderful resource called YouTube, you're sure to find a demonstration video there.

Also, I thought I should add this... When the system halts and the last frequency just keeps looping in the speakers (which causes that annoying buzzing sound), it's usually a problem with the CPU missing a cycle(s).

For a cooler, I recommend the Cooler Master Hyper 212 Evo - http://pcpartpicker.com/product/hmtCmG/cooler-master-cpu-cooler-rr212e20pkr2

For a power supply, any of the following would work for you - http://pcpartpicker.com/products/compare/cooler-master-power-supply-rs550afbag1us,corsair-power-supply-cp9020090na,evga-power-supply-220g20550y1/ Please note that I personally recommend the Cooler Master V series of power supplies.

Are you using the cooler that came with the CPU? Because if so, then I need to make you aware that both Intel and AMD ship their CPUs with coolers that are just enough to keep them from dangerously overheating.

If you happened to lose the CPU lottery and got one that has a higher VID (demands a higher voltage to be stable), then it's likely that it's making a little more heat due to the increased voltage. The fact that it's making a little more heat means that it may be just a little too much for the stock cooler.

This "Silicon Lottery" originates in how quickly CPUs are made, it wouldn't be as much of a problem if they would slow down the manufacturing process and take their time with each CPU.

To give you an example of the silicon lottery, let's say both of us went out and bought the same motherboard, i7 6700K's, same power supplies and everything else, even the same coolers. If you were able to be stable at 5.2GHz and mine would simply crash at 4.9GHz (using the same overclock settings) then that would mean that I lost the silicon lottery.

No i have a Corsair H80i water cooler thats why im suprised of the fact that its thermal throttling i have to demount it and mount it again see if its mounted ok (it should be)

Btw i ordered the new psu got the corsair one that you suggested with a pretty nice discount :) hope it solves the power issues gonna keep you updated about it I should be getting it tommorow

Ok that solved the issue thanks you were extremely helpful. Btw remounted cpu cooler applied new termal paste and still throttling but on the graph in Aida its shows that the 8th core is dropping frequency only pretty wierd. Any toughts?
