Display driver NVIDIA stopped responding, pls help!

Hi guys,

I'm having a pretty annoying problem since a couple of days, I'm not sure exactly when and how it started but here's what I'm experiencing;

When I don't touch the mouse or keyboard for a little while, say 2-3minutes, and then when I press a key or move the mouse again, the screen will go black for a second, come back up and give me this message: "Display driver NVIDIA Windows Kernel Mode Driver, Version 310.90 stopped responding and has successfully recovered." As long as I keep typing or moving the mouse it doesn't seem to happen.
When I play a game however the framerate will drop heavily after some minutes and then I have to alt-tab, screen goes off and on again when I do, alt-tab back to the game then framerate is fine again. But as you can imagine it's pretty annoying having to alt-tab every couple of minutes.
Now I'm by no means a computer expert (like I hope you guys are ;) ) but my little brother is pretty good with them but after trying some different possible solutions even he had to throw in the towel. I really hope someone here can help me find a solution.

Here's my pc specs:
i5 2400 Biostar motherboard (not sure what type but I'll find out if you need to know), 8gb Ram, 128gb SSD, 1TB HD, and probably most important; asus geforce 450GTS. System is about 8 months old I think.

What I've tried so far:

- updated nvidia drivers
- try several older nvidia drivers
- set nvidia power managment mode to 'prefer maximum performance/adaptive' (tried both)
-switched off intel speedstepping

I think that's about it, videocard doesn't get too hot, I can't think of anything else but it having something to do with going in somekind of idle state.. I dunno, I'm totally lost on this.
Please help! Winning tip will get a reward of your choosing :)

  1. usually the "driver stopped responding but has recovered" error message is due to a bad video card, mostly vram. i'd download video memory test
    http://www.majorgeeks.com/Video_Memory_Stress_Test__d5896.html
    or
    http://mikelab.kiev.ua/index_en.php?page=PROGRAMS/vmt_en

    and run that for a few passes, and I mean like 5-6 or longer. if you find any errors I would rma your video card if possible.
  2. Thank you I will try that and report back :)
  3. also because your card has overheated... (the fans on my watercooled gtx680 were stopped... while a ran the crysis benchmark... the watercooler got to 75 degrees before the driver stopped responding... )
  4. I don't know if the card get's too hot, maxes around 50 degrees. Dunno if that is too hot?
  5. okay so I ran a complete test, no errors:

    Changing video mode to 640x480x16...OK
    [5-2-2013 18:28:30] Test started for NVIDIA GeForce GTS 450
    Trying 16bpp RGB:565 mode...NOT SUPPORTED (Code: 887601C2)
    Trying 16bpp RGB:555 mode...OK
    Trying 16bpp BGR:565 mode...NOT SUPPORTED (Code: 80004001)
    Trying 32bpp RGB:888 mode...OK
    Trying 32bpp BGR:888 mode...NOT SUPPORTED (Code: 80004001)
    [5-2-2013 18:35:52] Pass completed (0 errors found).
  6. how many passes did it complete?
  7. I'm not sure :sweat: how many should I do and how do I do that?
