Hi all,
I bought a Sapphire radeon hd 6850 last week to replace my old 4870. Since then the computer has shut itself off thrice, every time when I have been running world of warcraft in the backround and browsing the internet. If I immediately try to turn the computer on, it will start but then turn off again, as if it isn't getting enough power. I can hear the fans slowly starting to spin, and then it turns off. So I'm thinking maybe the card doesn't get enough power?
I have a Corsair 550w PSU, a Intel 6600 cpu, and 4 gigs of ram, running Vista 64.
Also, I'm getting lower FPS in WoW than with the 4870, which I find odd. In crowded cities I can get as low as 5-15 FPS, while there was no lag at all with the 4870. I have the latest drivers installed. I've checked the temperatures of the graphics card and the cpu, they are fine.
Any suggestions?
Thanks
