I'd been noticing recently that my mini would periodically give me the gray screen of death when I'd boot it up, but after holding down the power to shut it down and restarting everything would be fine. I didn't think too much of it. I just moved out of my old place and into my new place and now my mini is doing it much more frequently. I just hooked it up for the first time since moving and I had to do the shut down/start up process three times before I got into OSX. Then I shut down OSX just to try it again... same exact results. It took three restarts to be able to boot up again. Does anybody know what might cause something like this? The only thing I can think of is that maybe something is up with the RAM. I did upgrade the RAM to 2x2 gig of OWC memory a few months back, but never saw anything like this happening. When the computer is running I haven't noticed any strange issues. HELP!
