Recently I upgraded my nVidia drivers (or more, it automatically did), and ever since I've been having trouble with my PC rendering Anything 3D, whatsoever.
The Direct3D ALU assessment is the most basic test of it.. it can't even begin before the system shuts down.
It's progressed to the system not even being capable of handling the screensaver coming on.
It's not an overheating issue - All temperatures are fine.
Not hardware related as far as I can tell, have replaced RAM, GFX card, etc. Soon to be replacing the motherboard.
However... I've been looking at so many topics on what could be the cause of these shut downs, not only on this forum, but globally, and have yet to find any solution that's worked for anyone else - that works for me.
Have run endless tests to better gauge where the problem may lie.. & have found absolutely nothing that can explain this in it's entirity.
Have rolled back drivers, even clean installed Windows 7 to eradicate any trace of recent 'new drivers' and run with legacy drivers instead.. problem still occurs.
Also read that it may be nVidia's audio drivers conflicting with the RealTEK audio, and thus eradicated any trace of nVidia's audio drivers too as an attempt to solve it that way - no luck.
On 3D processing the system has an instant kernal error (41) and thus of course, doesn't leave any trace of a minidump.
It shuts down instantly, and I have to physically turn it off at the power source before it will boot again.
I've stress tested the PSU, CPU and GPU - the only one that fails is the GPU (of course, due to the 3D).
But in replacing the GPU, and this problem still being around - I'm at a loss for where the fault may lie, other than with the motherboard itself.
Any help would be much appreciated..
