Back Again With Graphics Issue

It just seems to me that these cards generally shut down around 99 to 100 degrees and that your first post indicates that you are running some of these games at 90 and it has hit 99.

It looks like your card has increased by 30 + degrees from idle to playing a game for 10 minutes. I can only wonder what the temp is when it shuts down but it does seem that temperature may be the issue. Once again I would wait for additional input but these numbers are helpful.

Have you cleaned out any dust recently? It may well be that you need to add a fan or other method of cooling but I am not the expert.

 

The error code you have in your second screenshot (Post 18) indicates the graphics card ran out of video RAM, it seems to have been a common problem for quite a while with the OpenGL library for some games and even when using Adobe software to edit large pictures.

The 70c~ temp, if that is full load is a bit on the high side but nothing to worry too much about as you would be expecting anything between 50-70c while using a game (nearer the 70-80c if using Furmark to stress the GPU), if your case has a side fan mount (so it would be directly over the graphics card) then try mounting a fan there as that will improve GPU temps slightly.

Recommendations seems to be setting the CPU as the main PhysX processor, turning off Threaded optimisation (under 3D settings) & setting power management mode to 'maximum performance' (again under 3D settings), so try changing these under the Nvidia control panel and test your game again.

 

So i did all this and am still crashing in AC:B (not that it is saying much heh). I still need to try it out on other games, just thought that i would through it out there

 

Ok will see how a few of your other games go, if you're still getting crashes could you list down all programs installed on your PC, something must be conflicting somewhere to crash those games as that would seem to be the only likely constant after you had reinstalled your OS.

 

i attached 4 pictures of all the programs i have installed, i wasnt sure of a better way to do it other than that

 

Nothing seems out of the ordinary there either, most installed are games, Microsoft C++ stuff and a couple of other things which I wouldn't expect to interfere with your games crashing.

At this point I've only got a few more suggestions so unless someone else here can think of something that has been missed, I'm as confused as you are.

I would go to the Nvidia site and download past drivers, WHQL ones at first, try going back through the driver releases to see if Nvidia created the fault in a release of the drivers, remember each time to use the Nvidia Installer to uninstall the current drivers, restart the PC and install the new drivers.
Test your games with each driver release since you can reproduce the problem quite easily at the moment.

Also if you haven't already try confirming the graphics card isn't faulty, just try it in a friends PC if possible, assuming they have one of your games as well, otherwise just run Furmark on their PC (maybe 15-30 mins?) as you got a crash with that before.

As a last suggestion I would go with a full reinstall of the OS as much of a pain as it might be it would at least rule out any Windows/Program setting issue, just install Steam and a couple of your games (plus the necessary drivers, try an old version of the Nvidia Drivers Mid to Late 2011 first and then try the latest stable).
