Hi Everyone, First off, I want to thank everyone for the advice they gave on my problem, which for those who do not know or remember what it was, here it is:

At that point, I had replaced everything inside, so I stepped back and thought for a moment: "What did I change before the problem began?" I had filled two empty ram slots on my Apple 8*24 GC graphics acceleration card with two 4 MB 64 pin ram SIMMS designed for the Mac IIfx. I immediately removed these and guess what? My system started up! No problems at all now. My question: What is the connection between filling ram slots on my graphics card and my system not starting up? The ram SIMMS prevented the system from starting even when I was using on-board video (i.e. by-passing the graphics card entirely). I would like very much to maximize the ram on my 8*24 GC card so that I can use Adobe Photoshop 2.5 and other graphics programs on my Mac IIci. I read somewhere (LEM probably) that the card uses the same 64 pin ram SIMMS as the Mac IIfx, and they fit perfectly. Can any of you vintage Mac gurus offer any ideas on this problem?
