Hi guys im currently using a powerbook g4 15" 1.67ghz with 512mb ram with os 10.4.11, i know its a dinosaur but due to financial constraints i cant buy a new computer at the moment, when i bought this it was top of the line, 4 years ago lol, but anyway lately the computer is running like crap, especially the internet, programs load slow, web videos like youtube are becoming choppy and freeze every 2 seconds, i dont have a lot of music or pictures on my computer i have about 42 gb of memory still available on my 64gb drive, i try to run my software updates and java for mac 10.4 is something that hasnt been able to install for over a year now. im a casual computer user so i dont really keep everything up to date but now its starting to get to me. is there anything i can do? or do i have to wipe this thing clean and start from scratch?
