Problem running ALL games with DirectX 10-11

Oh dear me... it does sound more likely there's some hardware instability on your system...

Time to narrow this down further... do you overclock your CPU and/or your graphics card using software like MSI Afterburner or the like? If so, can you try and revert all your clocks back to default....

Another set of stress tests i'd like you try to rule out hardware instability would be LinX (LinX - A simple Linpack interface) for your CPU and RAM, and also Furmark (FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net) for your GPU.

For maximum stress run those two applications seperately first to isolate which component is cause, and then together (for at least an hour or until they complete), side by side while monitoring your temperatures... If your system passes those tests (i.e. doesn't crash or hard lock) then we can safely rule out hardware instability and blame it on the software 100%

I eagerly await your stress test results!

I did a clean reinstallation of Windows however,so I get a fresh OS to play and to make sure that there is no other software that might interfere when I'm playing.

Done installing Windows,I proceed to install essential drivers and 2 games: Just Cause 2 and Max Payne 3.

Even worse,this isn't solve anything. I could only play Just Cause 2 up to 45 minutes and Max Payne 3 (DX11) only 15 minutes. BUT there is a notification pop up message when Max Payne 3 exits itself saying something about "Nvidia driver error has crashed and recovered" (I don't really remember the exact message because it disappears so quickly).

So I used Driver Sweeper again but still no luck.
Next, I run the FurMark software and these are the results:
1920x1080 0xMSAA
FPS: Min 17,Max 29,Avg 22
Temperature: Min 34 degrees,Max 68 degrees (in celsius)
Time: 1 hour 5 minutes.

However I don't know how to use LinX because when I press start,nothing happens..CPU still 0-1% load and there's no increase in RAM use. And once I click start,the stop button does nothing when pressed..strange..
SO I used hyperpi and it runs without problem (I don't know if this equivalent or not).

EDIT : I managed to play around with Unigine Heaven and this happens :

Thanks for all the effort fnnoname!

That's really good work there refreshing your OS to exclude all other software possibilites... hmm if Furmark runs for an hour without any issues, your GPU should theoretically be in the clear... BUT that fatal error for Unigine still makes it suspect...

There're two last things i'd like you to try before i recommend a GPU replacement (I'm sorry =(),

1. Can you take a screenshot of GPUz and your game in windowed mode side by on your desktop with the sensors tab selected (e.g. for Max Payne), like below? (before it crashes of course)




2. Download MSI Afterburner (event.msi.com/vga/afterburner/download.htm) and either reduce the clocks (core, shader and memory frequencies) or increase the voltage of your graphics card slightly?

Your default clocks should be:-

732/1464/950 for core/shaders/memory respectively

(You mentioned your card was factory overclocked, perhaps the supplied voltage is not enough to run DX11 games stable enough)

How to: Once inside the program go to settings then check two boxes saying "unlock voltage control", and "unlock voltage monitoring"

After that just bump up your voltage and hit apply.

Try running the games after a small voltage increase?

Once again, thank you for your patience mate!

MSI Afterburner works with most dedicated desktop graphics cards from AMD/NVIDIA, so it should be okay...

Don't forget to post screenshots of Max Payne and GPUz, plus the MSI Afterburner windows of your detected clocks and voltages, and the lowered clocks too!
