I purchased a gateway with an Intel® Core™ i7-920 processor; 3GB DDR3 memory, and a ati radeon 4850 2 days ago and I am now getting a crash coarse on video cards. My card overheats and crashes my computer. I have changed settings of the fan speed to manual and 100 and have added a vid card fan cooler that sets next to the video card. I can open one copy of world of warcraft and it works fine but when i open more than one version the temps still run up to 80c and crashes the comp. My 2 year old computer could run 4 versions of wow and i never even knew you could check vid card temps. Is this card faulty? I have found similar posts of overheating with this card. What to do......
