I've had my Mini for about a year and I've been running OWC RAM since say 1 (2x 2gig). Just before Summer I started getting the gray screen of death periodically when I'd boot up the Mini and would have to take several tries until it would boot up. I put the stock RAM back in and it worked fine again so I RMA'd the RAM back to OWC and they sent me a new set. All was well until yesterday. The same thing happened to me for the first time in ages and it took me three hard resets today when I got home from work to even get it running. I have a bad feeling the same thing is happening all over. Is there anything I can do to examine the RAM (software tests, etc.)? I've been running OWC memory in my Macbook Pro for probably almost 2 years without problems so I don't know if I'm just unlucky or what... If anybody thinks it could be something other than RAM I'm all ears.
