Yesterday Nvidia released the new 196.75 drivers, which gained quite a bit of attention due to the substantial increases it offered for graphics card (I believe it was 10-30% for all games tested, the page has since been removed). However, today it turns out that this update has the potential to kill graphics cards
Nvidia had this to say:
Some users have claimed to have found a fix, but so far this is unconfirmed.
I consider myself extremely lucky. I thought it was bizarre when Dragon Age suddenly started demanding 98% CPU and the temperature of my computer skyrocketed. Others have reported that after this happened, there was a burning smell and their computer crashed. Mine seems to be working fine, hopefully no long term damage was done.
