Nvidia GeForce GTX 460 - Crashes when using videogame application.

[Frostnight256]

Whenever I start up my computer and play any video game, I can run everything perfectly at the usual FPS of 60. Within ten to thirty minutes, the game starts to slowly lag, and my my audio starts to sound all static-like in which my frame-rate drastically drops to 5. Shortly after this happens, I close the application but the video lag and sound static still persists, in which I restart my computer. After restarting, I do not encounter this problem again until I shutdown my computer for the night or take a large break (One-Two Hours).

(The bottom paragraph is exactly what I did in order.)
I removed, and reinstalled my graphical drivers, but that didn't solve the problem. I rolled back to a old, yet useable driver but it didn't solve my problem. I then re-formatted my computer hoping it would solve it, however it didn't. I found out my motherboard's chip set and Wired Networking, and RAID were out-dated, so I updated them. Still no solution.

Operating System is Windows 7 - Ultimate.
Ran the cmd -> sfc.exe /scannow and received no errors.
Didn't receive any blue-screens, nor "Driver has stopped working."

I apologize If I have a lack of information.

Go ahead and follow the bsod posting instructions, a copy of the app and system logs may help shed some light on the problem.

Heat is of course a possible problem as well. When was the last time you cleaned out your system?

Cleaned it out a week ago, using compressed air. Before that, cleaned it a month ago when I first started having the problem. It's not a heat issue, It would stay at a constant 34-40. Here's the system logs.

hmm... nothing extremely telling outside of a bunch of app faults/hangs mostly related to wow and saint's row apparently.

To be honest this is seemingly all software side, so let's try snoozing/disabling your active av while gaming and see if it still occurs.

Sorry for this question, but what is "av?"

Active Visual? And where can I find it?

 

[Maguscreed]

sorry , meant antivirus, I believe you are using AVG right now.

The problem happened to me again. Took a long break from the computer in order to start the problem again. This time, It started when I was playing Saints Row, and it came to the point where I couldn't use the SF Diag tool to take the logs as it froze the computer and I had to restart it.

Here are the logs I got from using it after the restart.

Also did it without Virus Scanner.

Ran the cmd -> sfc.exe /scannow again, didn't detect anything, but I know this problem will happen again when I start my computer up again.
