Heya, im experiencing quite a bit of a problem with my macbook pro and i suspect that i might have something to do with my graphics card. My comp was bought last summer (2009 ) and it's one of the ones with two graphics cards, one for higher performance, one for better battery life. Whenever i run the normal settings for battery life my laptop works completely fine, however, as soon as i switch to the higher perfomance card in energy saving setting my laptop starts freezing up. Sometimes a freeze takes a few mins and eventually u can use the comp again, but most of the time it will be a proper hard freeze and i wont be able to do anything but restarting my comp by holding the power button. Another thing i find very strange is that my laptop will run completely fine, in high performance settings, if im quick enough to start up a game (like world of warcraft, heroes of newerth..) before it freezes. Once i have a game running, ill be able to tab out and use the computer normally (although the screen does flash sometimes :S ) and it wont freeze again until i shut down the game. Model Name: MacBook Pro Model Identifier: MacBookPro5,3 Processor Name: Intel Core 2 Duo Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 3 MB Memory: 4 GB Bus Speed: 1.07 GHz Graphics: Chipset Model: NVIDIA GeForce 9400M Chipset Model: NVIDIA GeForce 9600M GT Since i havent really been using it for much more than uni work before, its not until now ive come across this problem. Ive been googling my problem and the graphics card but i simply cant find anyone else with a similar problem.. Do i need to take my comp to the shops..? Would appreciate all the help i can get!
