Hello, I have a Mid-2010 Mac mini with a 2.26 ghz core 2 duo, and 2 gigs of RAM. It usually runs fine for the most part, and I haven't had any major problems with it since I bought it in July of 2010, until now. I was playing a popular online game as my computer suddenly froze completely. There had been lag in the game, but I realized much of it was client side (coming from me). Now as I tried restarting my computer, I got many different results depending on what I did to start it up. I tried booting in Safe Mode, and got a loading bar beneath the spinner, so following directions from an Apple post, I tried to restart it regularly. This time it did not sound a chime, and the grey screen didn't appear. I tried holding down option to select my hard drive. My hard drive, and a "recovery drive" appeared on the gray screen. I tried selecting mine with my keyboard, but the system froze as I tried to do this (I don't think my batteries died). Finally, I let it cool down a while so I could come back and boot it up. It did, and got to the gray screen and even the Apple w/spinner. Yet it froze again. My gut tells me I need to upgrade my RAM (tried to reset PRAM too) but is there another problem? Thanks.
