I was playing Oblivion with a Radeon x1950 crossfire ready card and it was doing fine at high settings,but when I added a x1950 crossfire edition and set them in crossfire mode the game looked like a movie, for about half an hour then crashed. When I rebooted and tried to load the game again the screen looked like something out of the movie The Matrix and then rebooted itself. Now one card won't work at all and the other still has the same problem. I have rolled back the drivers using driver cleaner.net each time and still no help.I also reinstalled the game. I tried setting the game at low settings and it still crashes.
I have also run dxdiag.and when the test gets to full screen mode "BAM" reboot!
Any idea whats going on here?????

You are both right on
I have an alternate power source called "booster X3( a waste of $90) I unpluged it and pluged in my PSU and that solved the graphics problem but one of the cards is still dead. I have to try to get a replacement from HIS.
