I recently got back my 15" 1.25 from repair for the second time...arg!! Finally they seemed to have fixed everything [knock on wood]. I purchased a 512mg RAM chip from OWC. Unlike the chip I had previously purchased from 18004memory, it has not caused kernel panics or any problems during 90% of operation of the computer. However, I have noticed that anytime I try to play a game (demos like unreal, ghost recon, nascar...etc) the computer freezes during the first few minutes of game play and the screen turns black, forcing me to restart. I am running OS 10.3. I am wondering if people think the freezes are likely from the RAM chip or maybe something else is at fault.
Any suggestions would be helpful.
