Whats going on with my GPU?

Um. So i was playing some MoH SP and everything was running fine and dandy until suddenly the screen goes black and comes back and the game is running at 10 fps. I have a GTS 360m and its barely 2 weeks old in a new laptop. All games i tried playing were performing horribly afterward.

So anyway I had overclocked it to 600/1600/1900 from the stock of 550/1525/1825 i think. My temps were in the 90s all the time but i wasn't paying attention for a few minutes so i thought maybe it was overheating and it throttled itself down. I doubt that though because my max temp was like 94c and i have seen it go to 95c max in the past.

 

Did you try another driver?

 

um this just happened and im on the latest nvidia forceware drivers. As i said, everything was running fine until this. Also note that i found out my GPU's core/shader clocks dont increase when i start a game so the temps stay really low.

Edit: Restarting my comp fixed it but i wanna know whats up with this issue.

 

Your driver crashed, probably due to your overclock being more than your system can handle.

 

youve also voided your warranty as you overclocked.
if you return it for a warranty repair and they suss out youve overclocked it and you need a new graphics card then expect to pay much wonga.

 

Nice scare tactics there Mr DJ, they have no way of knowing.

 

I think the system simply throttled.. thats y restarting fixed it... was it like a hot afternoon or somethin?? i find that my laptop usually throttles when the ambient temperature is a lil high..

 

It was late at night lol. I wasn't paying attention to the temps. Ill try resetting back to stock clocks and see how that goes. This thing has barely been OC'd for 3 days.

 

This means the overclock was just barely unstable, and after the display driver crashes, the clocks are locked at about half of their stock maximum, hence the lagginess. Whenever this happens just set your GPU clocks back to stock and reboot. It will be able to go back to stock clocks and be fine.

 

so does that mean i should reduce my clocks a bit? Or is this normal?

 

Yes, try a lower overclock, and keep doing so until this doesn't happen, and that means you've found stable clocks.

 

Yeah this happened with my old 9600M GS.

After I OC'ed it by almost 50% it would crash at times and then the performance becomes super crappy.
