My graphics card might be faulty. PC kept shutting down and refusing to boot up until after a few minutes, only to die again. Each time it recovers I need to reconfigure my BIOS. A quick google search showed a huge failure rate on GTX 280 cards, with them hitting 110 degrees only after a few minutes of use. I need to go back home and verify that my card is indeed hitting those temperatures, and if it is, see if I can mitigate the problem by improving airflow. Anything to avoid sending the card back to the US for RMA and possibly getting another defective card anyway.
Ended up having to raid on my notebook last night. 🙁
