Game crash prevention help

kwohld​  For future reference, LiveKernelEvent refers to a broad category of error, "Live" being in contrast to the BlueScreen of Death.  As in, BSOD means Windows initiated an emergency shutdown to protect the computer, whereas with LKE, the error was serious but not critical enough to require a shutdown.  The question is then what type of error it is.  In your case, it's 141, which is a timeout of the video driver, and your dxdiag lists several, along with a couple BSOD 119 codes; 119 is an error with the video scheduler.

So under normal circumstances, pulling the graphics driver is absolutely the right move and really the only one to make here.  Display Driver Uninstaller is the safest way to cleanly remove the driver.  I'm not sure where you read that it can damage your computer, but that's not true in general—even Nvidia forums recommend DDU quite a lot.  When it does cause problems, the cause is typically user error (e.g. installing the wrong driver, not reading directions), or there's a hardware error that was crashing the driver, in which case DDU isn't going to solve it.

However, in your particular case, you've plugged your 4k monitor (or TV?) into the motherboard rather than the RTX 5070, and that is likely the problem here.  So please plug the monitor directly into the GPU.
