Hello, all. I have a highly upgraded Digital Audio G4 tower that recently stopped powering up correctly. The power button light will come on, and I hear the fan, but that's it. I have to push the CUDA button, then power back up. I have to do this every time. The only thing I've done lately is remove the processor to put better heat paste on it. I've been doing that for years, so I know it's done correctly. Anyone know what's going on?
