Is it some driver bug or dying hardware? The card is not overclocked (Gigabyte GTX 275)

Everything went back to normal after rebooting.

Wow I never seen anything like that before. Did the same issue happen to other games or just one game L4D2?

Re: I was playing l4d2 and suddenly this happened...
 

Might of gotten hot? or maybe there was a memory leak in the graphics ram? never seen anything like that.

Looks like some crazy interference to me. Got a mad scientist in the house?:D

Are you using the 197.13 beta drivers? I'm using them as well and getting the same results.

I was about to create a new thread about this issue. I have an EVGA GTX275 and today I had this issue when I was playing a flash game. It happened only once. But when I play games like Splinter Cell Conviction, the game will have sound issues and eventually freeze my computer.

Re: I was playing l4d2 and suddenly this happened...
 

I switched to a different set of drivers, and the problem is fixed.

Re: I was playing l4d2 and suddenly this happened...
 

Problem was fixed in my end as well. All I did was get rid of all the dust that accumulated in my graphics card. If it happens again it may be the drivers I am using, but so far all is good.
