I am getting out of ideas to fix a graphics card problem, so I'm posting here, in case someone has an idea. Not so long ago, I started to have instant BSODs whenever I tried to log in. I can't remember what the code was, but it mentionned nvlddkm.sys. My card was a 8800GT. I looked up on the internetz, and came to the conclusion that maybe my card was faulty, so I decided to bought another card.
I bought an EVGA GTX 560 Ti with 2GB of memory. The card runned with absolutely no problems for a day or two, then, whenever I play a game that is kinda gpu-intensive (like Starcraft 2, Skyrim, etc). When I run games such as Diablo 2, I get no problems. When it crashes, the BSOD code is 116.
Here's what windows is telling me about it:
OS Version: 6_1_7601
Service Pack: 1_0
Sometimes, when I'm not running anything intensive, my screen goes black for a few seconds and then comes back and Windows tells me that the driver wasn't responding and recovered. When this starts to happen, it does so every 5 minutes or so and eventually my screen begins to tear up.
I should also note that when I use a Quadro FX 570M, I get absolutely no problems, even when running SC2 (however I have to run it at Low settings with that card)
Here is my current setup:
Windows 7 64-bits
EVGA GTX 560 Ti 2GB
4x1GB DDR2 RAM
Intel Core Duo E6850 @ 3.00 GHz
2x2TB Barracuda Seagate Harddisks (setted in RAID 1)
CoolMaster Silent Pro M 850W
Things I have tried so far:
Changing the PSU (had the stock 375W that came with my Dell XPS 420)
Uninstalling and reinstalling drivers
Trying other RAM (tried 2x1GB DDR2 ram)
Ran memtest for a while and no errors reported
Updating the graphics card BIOS
Reset the CMOS
With my 8800GT, formatted and reinstalled windows.
All of the above did not worked. Anyone out there has an idea?
