Mac 8gb RAM upgrade doesn't let me run source games >:(
Ok, so I have Garry's mod, TF2 (team fortress 2) and CSS (Counter Strike Source). So on my birthday I went to go pick up a RAM upgrade from Mac Mall. So Mac Mall installed the RAM (im trusting they did it correctly) and it read fine, so now I go home and start playing TF2 when my computer freezes and a sign comes up and says "You need to restart your computer. Hold down the power button for several seconds or press the restart button." So first off, This only happens with the games I listed above, but I can play any other game I like and this won't happen. And Second off, WHY DOES THIS HAPPEN TO ME IT HAS NEVER HAPPEND BEFORE THE UPGRADE!!!!!!!
Heres the specs of my computer, 2.26 GHz Intel Core 2 Duo, 8GB (it was 4GB) 1333 MHz DDR3.
