Riba, I do have the original graphics card inside; didn't do any upgrade. W.r.t. memory sticks; they've worked flawlessly for more than three years. How could they suddenly become 'bad'? I once more tried several times to boot from the Apple G4 Cube Hardware Diagnostics CD but this won't work from the MCE DVD-R drive that I installed in the Cube. I really don't look forward to replace it with the original CD-ROM drive merely just to figure out what's wrong. Running TechTool's 4 Advanced Diagnostics doesn't show up any problems with the Cube. I also have run 'memtest for OS X' (http:// www.memtestosx.org/) in single user mode but also that didn't report any issues. Any more help is appreciated. cheers Rob On Jan 14, 2006, at 20:29 , Daniel Galley wrote: > On 14/01/06 17:02, "Riba" <riba at ml1.net> wrote: > > Also a frequent symptom of bad memory stick. > > Daniel > > >> On Jan 12, 2006, at 19:55, Rob In der Maur wrote: >> >>> Hi all, >>> >>> Suddenly my Cube is experiencing loads of kernel panics.
