I purchased a 2011 Mac Mini yesterday with the i5 and 500GB. I immediately upgraded it to a 7200 750GB HD. I also changed it's memory from the measly 2GB to 8GB using brand new corsair memory purchased off amazon. For some reason at random times using the computer I get the black screen of death asking me to restart the computer. I have tried to narrow it down by only putting 1 stick of memory at the time to see if it does this as it can be a faulty memory stick but since it happens at different times it's difficult to narrow it down. What do you guys recommend?
Thanks
