Windows 7: Recent BSOD problems - nvlddmkm.sys

Windows 7 Ultimate x64

Hi Rich,

Thanks for the help. I'm not ignoring your advice - I'm totally incapable of getting any video output at the moment. I can't get past POST at the moment, so I'm unable to run memtest86. I fully intend to check the rest of the hardware once I get the video card operating (assuming I can at all), as I've had issues with 0x124 in the past.

I was able to play TF2 without artifacts etc. until this point.

However, what I'm wondering is if it might be an issue with power. The reason I ask this is because this card is a 9800GT "green" edition - it doesn't have require an extra power connector; it derives all the necessary juice from the PCI-E slot. I did a bit of Googlin' earlier and some people suggest that this might be a problem with insufficient power going to the card. Am I clutching at straws here?

Also, am I better off asking this in the graphics card forum? Please feel free to close the thread if I should.
So do I understand correctly the video card failed on both your and your friend's computers? If yes, then it would see the video card is at fault.

Conversely, you can put your friend's video card into your computer. If the card is the problem, then your system should boot right up.

If I'm mistaken about the two computers, please let me know. Good luck!

Windows 7 Ultimate x64

Yeah, that's right. In both systems, the card works completely normally for a random length of time (usually about 45 minutes, though I had it working for most of the day yesterday - I had it working for about 12 hours straight, with absolutely no problems) until something goes wrong, the display goes off and the fan sticks at 100%. Once the PC is shut down and restarted, the fan spins up immediately to 100%, stays like that and there is no video output. Unplugging the PC and leaving it for about 15 minutes seems to fix this, but it inevitably happens again after another random length of time. It's very, very strange indeed.

What I'm wondering is if this might have something to do with the card not drawing enough power. I can't really afford to replace the card at the moment, and the RMA process involves shipping the card to Hong Kong (I live in the UK) which I can't really afford either. So, if there's something I can do to fix it, then I'd like to explore all the options

You're gonna have to rma the card.

Yeah, this is what I suspected. Oh well, it's typical of my luck. That's the second card I've had fail on me since June.

Thanks for your help everyone, it's very much appreciated.
