Long time user of Windows, and now want to see what's all the buzz over Mac!! This of course means I'm new to Mac. I bought a used g4 (Quicksilver) and decided to upgrade the Processor from 867Mhz to a 1.6 Ghz Processor. I also wanted to have the ability to use HD >127gigs; therefore, I purchased a Sata controller card and a USB 2.0 controller card. This is attached to a 22in Samsung Lcd. I using the original Video Card (Ati 128 rage pro). My problem is that I usually leave my PC 
--okay Mac On--, but upon checking it after it goes to sleep, I have to power it back on because I can't wake it from sleeping. Then there's an error code/info.
