Alright so about a year ago I purchased a used 2009 mac mini off of ebay. It was running great, I was using it as a media center in my living room. I decided that the 120gb hard drive wasn't enough space to hold all of my media, and the 2gb of ram wasn't cutting it either. So i purchased 8GB of 1333MHz DDR3 ram, and a Western Digital blue 1tb hard drive. So I performed the upgrade, installed the hard drive and RAM. I also upgraded the software to Mountain Lion. Well a few days after I performed the upgrade the computer would randomly shut down and restart. Once the computer booted back up again it would show an error message saying "your computer has been restarted because of a problem." I continued having these problems, so I figured the older computer just couldn't handle running mountain lion. So I downgraded to snow leopard. I believe the computer is acting even worse now than it was before. Safari quits un-expectedly all of the time, flash video like netflix and youtube crash constantly, and the computer makes me re-install microsoft silver light everytime it crashes while i'm watching netflix. I'm completely baffeled as to why the computer is doing this. Does anyone have any experience with something like this? Did I mess up something simple? Let me know, because this computer is driving me crazy!!
