Crashes while playing games and I think it might be overheating

[Finch1996]

Hello everyone,

So im comming to you in hope to find a solution to my problem.

The problem: When im playing a game that is a bit heavy and ressource demanding(Blade&Soul for example) i get crashes of the game and a black screen with my screen telling that there's no signal, and shortly after 2 seconds it comes back to life with the game crashed.

I downloaded OCCT and MSI Afterburner just to run some tests and it seems that the GPU would crash when it reaches a temp of 70°C and the CPU a temp of 80°C. I used Afterburner to modify the profile of the GPU fan for a more agressive one to keep temperatures lower and I did the same for the Chassis fan's profile in my Bios settings. Now it gets very noisy and i have to keep an eye on the monitoring of afterburner to not get to high temps to prevent crashes.

It's kind of weird since games run at high FPS without stuttering and instead of the game's FPS lowering down it's the system who crashes.

My rig :
CPU: Intel Core I5 4690k 3,5GhZ
GPU: Sapphire Radeon 270x 4gb
Motherboard: Asus H97 - Pro
Ram: Vengeance 8gb one stick
PSU: Cooler Master 700W Silent Pro Gold
Chassis: Zalman Z11 Plus

Thank you in advance for your responses and i really hope to find a solution

Must be video drivers. There might show up a message in the corner sometimes saying "Video driver stopped working and recovered" or similar. Not everytime this bubble appears. I think reinstalling/updating video card drivers might fix it. Happened for me in many builds but mostly on NVIDIA GPUs.
AMD GPU temps are like that, its normal.

Already did that i went from 14.12 the omega which are reputed to be stable to the most recent one's but the crashes don't stop.
Thank you for your fast answer

So the problem might be with either GPU or PSU. There are few options you can try, some of them require additional hardware.
I believe you are on stock speeds.
> Try providing additional power to video card using 2x molex to pci-e cable instead of pci-e power connector from PSU.
> Change the video card or just try yours with another build (like ask a friend) with same drivers you are using.
> Roll back even more...

Also i forgot to mention but when i run CPU tests with OCCT it shows an overclocking percentage of 17%. Now i don't know if the cpu is overclocked by the motherboard since I can't find an option in the Bios settings to fix the core speed.
(I never tried to overclock it since I don't really need that much power and I'm using the stock ventirad until I replace it).

Maybe the problem can come from there ?
