I believe this is a problem with my video card, but I would like to see if anybody else could confirm this for me.
One day I started having issues with my computer. This problem occurred when every I tried to run some video games. When it would attempt to switch to full screen I would experience a hardware failure of some sort and my computer would immediately loose power and restart. I thought that my old power supply might not be putting out enough power any more so I replaced it and that did not solve the issue.
The odd thing is that when I run never winter nights it would run for a short period of time, until all of the production logos and credits had been displayed and the actual game started.
