Hi Guys

I am having a small problem and i just want to pinpoint or just get a general idea of what the problem could be.

On occasion when playing game COD4, SC2 ect, my PC would halt, show a black screen and come back after 2 seconds. When it comes back, the frames almost drop by half, its like I'm getting massive FPS lag and i cant understand why. When i restart my PC its fine.

I have overclocked the card and my CPU, but the temps are fine and far from overheating.

My card reaches about 70 degrees under load, with 60 % fan cycle, which is fine. CPU reaches 40 degrees under load, but i have a cooler master cooler on it.

I had a mate of mine reckon its a driver crash on my graphics card, as he has had a similar problem before.

So after all the nonsense I have sprouted here, I just want to know from you guys is there anything else that would cause this to happen, and would you give me other suggestions on what it could be.
 
VPU recovery is kicking in. Try disabling it & back off on the gpu OC.

I'm guessing its an ATI, no? (Weird that you didn't even mention brand btw)
 
I've seen stuff like this happening on my brother's Dell laptop when his graphics card temperatures exceed like 80'C, then it switches to a low speed profile, which makes gaming impossible.

Could you tell us more about your system specs: CPU, RAM, GFX, PSU
as well as your operating system and graphics card driver version that you're using?
 
Soz guys, posted half arse.

Gainward GTX275 (nvidia) (OC) but only a fraction
Q9400 2.6 GHZ (OC) to 3 GHZ
4 gig axe ram 1033mhz
730 watt PSU (Raidmax)
Windows 7 64 bit

Thanks ;D

My nvidia will do that on unsafe OC's, well backs down to stock. Also 460's sometimes get stuck at 400 core which requires a driver re-install. Both ATI and Nvidia have their problems.
 
I'm 100% sure it's an overclocking issue. I also overclocked my GTX280 but I went a bit to far and my games keep on crashing. Sometimes my screen went black omes back after a few seconds and my gpu is in power savings mode. So maybe tune down the overclocking.

also temperatures is not everything. You card can be sitting at 20C under load but doesn't mean you can overclock it till it reaches 80C.
 
I think your card is not getting enough volts for your overclock, so when it really hits full load it becomes unstable. Try running furmark with your OC and see what happens, or the msi kombuster that comes with msi afterburner (free downloads).

Or a driver issue is always possible.. You never know..
 
I have taken of the OC for now, I do remember at one stage I had artifacts and started pixelating. And since then it seems to have given the issue. I have also updated the new drivers, has not given the issue since. But again it still worrying. Would you say its time for a new card maybe? its already been three years.
 
So i managed to get my hands on a GTX 560 TI, and its seems nothing has changed, I still get decent frames but still not what at should be. I have a mates i running smaller Rigs and managed to get more FPS than me. Now I'm starting to wonder if it could be my CPU?
 
Run Process Explorer, and monitor each CPU Core individually.
Then also run like MSI Afterburner, to monitor the GPU usage.

The framerate shouldn't drop like you've described in your first post.
If the framerate is consistently lower than you're friend's rig, then perhaps you should make sure that you're using the same level of detail in the game, as well as the resolution - and post his CPU model# :)

had to rub it in lol :P its the house we stay in . ambient air is ALWAYS cold + tiles + card gets cleaned frequently + no OC.

OP must underclock the gfx and check if it helps, if not , set alles to default (ram, gfx , cpu clocks) and check again. Also check gfx detail in game (as pada said) and also your nvidia custom profiles for games. I remember back in the day a specific game was lagging insane, but i had some settings that werent supposed to be there as my card couldnt handle it lol IE (vsync + lots of AA)
