I just got a Sapphire 11168-02-20R HD 5670 512MB GDDR5 and installed it on a fresh Window 7 Home Premium installation, and I keep getting these graphic glitches. It seem like if the graphic card is powering down, and needs to warm up, the graphic glitch seem to disappear after a while, especially in games after I get past the main menu.
This is some examples of what it looks like, its like small boxes that just flicking around the screen and sticking around sometimes.
Also this is my hardware at the moment:
Windows 7 64 bit Service Pack 1
Intel Core i7-2600K, 3.40GHz
8 GB DDR3
Sapphire 11168-02-20R HD 5670 512MB GDDR5
Installed the newest ATI drivers found on the website (11-12_vista64_win7_64_dd_ccc_ocl.exe)
Any ideas what I need to do to fix it?
