I have a Beige G3 and Tiger running on it through XPostFacto. Randomly (mostly when the HD is reading/writing more often), the video blanks out and the monitors LED turns amber.
I have tried this: http://www.applefritter.com/node/6968
The last one (the easiest) didn't work, upon using Spotlight, the video blacked out.
I also tried the one using Pico in the terminal and replacing entries in the .plist, and that still did not work (matter of fact, now the Mac won't boot. It boots to the grey screen, and as the spinning thing appears at the grey screen, the video switches to 48 Hz, and looks ALL corrupted.
Any help? I am right now booted to OS 9.2.2..
