What's the best driver to use for my GTX280 video card in Win7 64-bit?  Every version I've tried since installing Win7 and possibly before that in Vista64bit, I'm plagued with "Display driver nvlddmkm stopped responding and has successfully recovered." blackscreens in FSX as FSX is unable to recover from a video driver crash....

 

I'm currently using 331.82, and have had this issue since before 306.23 (the earliest version I've had since upgrading from Vista to Win7, but I'm sure I've had the same crashes in Vista using earlier driver versions).

 

Any suggestions on which video driver version would be most stable in 64-bit Win7 for FSX?

I wonder if your GPU is starting to show its age.  Possible overheating or bad onboard memory could be an issue.  Have you installed the video drivers as per the instructions?

I don't know if it's overheating, Speedfan shows it not getting any higher than 60C (and typically lower than that), and from everything I could find, that's far from overheating (or every site I found was wrong), and I blasted it very well with compressed air quite recently. The only other game I've ever gotten this video driver crash in is Omnibus Simulator. The rest of the hardware-intensive games I use cause no problems.

 

I'm on my laptop now, will have to look further into the methodology of how to completely obliterate one set of drivers before installing a fresh one next time I'm at my FSX computer.

 

Is there an app specifically to test video memory?

Here's something I found:

Run the GPU memtest so far...  No errors in 10 passes and temperatures remaining within its "normal" range..  However, did find one interesting thing....

 

My 12V line is highly unstable and undervolted....  I suppose the next thing to figure out is which component is failing, the motherboard or the power supply....

 

Edit:  Ok, never mind... After a quick google, I see that this OCCT reading doesn't really mean that it's accurate....
