Hello everyone. I've had an NVIDIA GeForce 9800 GT card for 2-3 years, and today it decided to stop working. First thing that happened was my computer froze. After rebooting, it would work for a short while (2-3 minutes) before doing the same thing. Now it doesn't do anything at all. I took it out, and reconnected it, and it didn't help. I'm now using the onboard graphics card. Is there anything I can do to troubleshoot my card, or is it done for?
