Just built a home rig with an A8 5800 on a Asus A88X-Pro. Stock default bios (no overclocking or tuning). Loaded Windows 7 Home. Everything is working with the generic windows drivers. But when I load the Catalyst chipset and display adapter drivers, I get a buzzing sound, screen dithering and a freeze requiring a power button reset. I can do file operations, change system settings, etc... The memory DIMMs have been tested good. So it has to be the CPU or the Motherboard... Anyone seen this before? Did I get a Lemon(s)?
