Graphics card dying or underpowered.

Hi there,

I have what I thought to be a perfectly operational graphics card until recently when it started to majorly malfunction during one game, Arkham City.

The malfunctioning starting when I was about 15% into the game, I didn't have one issue before that (about 5 hours of game time). What happens is the game locks in random areas after 3-10 minus of play, if I attempt to alt-tab or ctrl-alt-del it will most likely flicker a few times then BSOD.
Smetimes it will go to jthe desktop successfully and generally there will be corruption of some kind on the screen until I restart the computer.

Since this started happening I have changed video card drivers several times, reinstalled my Wndows 7 operating system completely, pulled apart the video card, reapplied thermal compound and cleared it of dust. For some time I thought it was temperature. I did get up to the low 80's during gameplay. But after forcing the fan speed to 80% and seeing it crash at 45 I decided that wasn't the problem.

Obviously the likely event is that the card is dying, however I thought since it's only occurring in one game it could be a power supply issue, which has happened to me before.

Any thoughts would be appreciated.

Thanks

Before you conclude that it isn't heat, try installing a case fan and directing the air at the video card.  Failures occurring only in intense game mode usually mean excessive heat; power is only a factor for high-end gaming cards  that don't have a decent power supply.  Also, the temperature you are seeing may not be correct.

Hi guys,

Just an update.

@jamietoner - I'll obtain this soon. It is a 500W PSU. I'd be surprised if the wattage was insufficient as there were no changes to my hardware for several months from when i started playing the game (with no issues) until the issues started occurring (6 or so hours into the game).

@althakar - Have tried the most three recent NVIDIA drivers and have used Driver Clean to remove the existing drivers before testing.

@nobus - I've investigated specific problems with the game and there are many (as per usual) but not too many pointing to BSOD crashes.

@callandor - I'm confident that its not heat. I understand your reasoning but i cranked up the Video Card fan to 90% (from 20%) and it significantly dropped the heat. Even if it is reporting low there is still a good 40 Degree drop with the fan on full.

that points to :  nvlddmkm.sys    GRAPHICS_DRIVER_TDR_FAULT
so it can be a bad video card, since you have updated drivers and OS
