Hello,
I recently downloaded Snow Leopard 10.6.1-10.6.2_SSE2-SSE3_Intel-AMD_by_Hazard
and I have many problems to install it. The installer does not start, start out thousands of colors and the monitor is grated ... I've tried several DVD's of Mac OS, the one I started the installation was Leopard install 1.5.8 but after I boot the system and when the apple appears on the frequency of the monitor goes crazy and apparently gives an ACPI problem .

My laptop is as follows:

Acer Aspire 5253
AMD Dual Core CPU C-50
Chipset: AMD K14 Hudson
Ati Radeon HD 6250

Can you help?

Thanks!
