Hi all. I recently purchased a 5770 to put in a 2 year old computer that I was given by a friend. After installing the card I noticed that when I turned the computer on the fan on the graphics card would repeatedly speed up and slow down for about 20 seconds, preventing the system from booting up for the entire 20 seconds. This in itself is annoying as it adds 20 seconds to my boot time, but it also makes me wonder if there are other problems with the card. I tried putting the graphics card in my old motherboard and found that it booted up fine with no sign of the fan speed up problem or 20 second boot delay. So I take it from this that my motherboard is at fault or there is some sort of conflict between the graphics card and the motherboard.
I've also noticed that anti aliasing isn't working in any of the games I've tried. So far I've tried Starcraft 2, Civilization 5, Battlefield 2 and found that adjusting the anti aliasing in the ATI catalyst control centre made no difference. I was also unable to turn on AA in the game's video settings with the exception of BF2, but I don't think AA actually came on as I saw plenty of jagged edges. I've tried installing Catalyst 10.6 which is the latest XP driver from the Powercolor website, and also 10.10 from the ATI website, neither have made a difference.
Here are my specs:
Athlon x2 5200 2.7ghz
Gigabyte GA M61PME-S2P
Powercolor HD 5770 1GB GDDR5 DVI HDMI
2GB RAM
200GB WD HDD
Antec TP 750 PSU
Windows XP Professional
Anyone have a solution to these problems?
Thanks
