I've got a 2008 core2duo Mac Mini 1.83ghz that has SL 10.6.8 on it and the machine has served me well these last 8 years. I don't use it much anymore. Just as a file server. But it now it has developed an issue that it will just freeze up. No keyboard, no mouse input. Happens all the time now. When the computer is just sitting idle. Not in use. Power saving is off. No sleep. Have tried unplugging USB stuff. Only thing connected to it is monitor and keyboard. Only way to get it going again is a hard restart with the power button. Tried resetting PRAM and checked disk utility. No help. I think this machine is on its way out. It's not like I haven't gotten my money's worth! Perhaps I could try reinstalling the OS, yuck, but I have my doubts that will help. Also Ethernet port died a few years ago. It has a OWC 128GB SSD & 4GB ram installed by a mac shop a few years ago. No issues in the past with those. Whaddya say? Any last ditch keyboard start up tricks to try before either I reinstall SN or toss this thing in the trash? Thanks.
