Well last week I powered up my iMac to discover it had gone deadskies. It'd boot to the Apple logo (Jag 10.2. 8) , and then freeze, and display static. (like a bad digital TV picture, sort of)
I've tried a 10.1.3 CD, it kernel panics. I've tried both OS 8.6 and OS 9.2.1 CDs, and on both of those it will either hang on the Happy Mac or the "Welcome to Mac OS" greeting.
I've tried switching out RAM. I've tried switching out CPU cards. I've tried switching mobos. I've tried using it with an external monitor (all my diagnostics have been done on an external display to nullify any issue with the PSU not putting out enough power). I've tried resetting the CUDA.
Last Saturday when I first discovered this, I pulled the PRAM battery and let it sit for a week without the PRAM battery. This afternoon I got it to boot all the way into OS X 10.1 (booted from the CD) exactly once. It has never done it again.
Anyone got any ideas as to how I can get 'er going again, or is she gone for good this time?
Edit - I neglected to mention, its a tray loading iMac 333 (Rev. D)
