Hello, (FYI- I know very little about computers. Some pieces of information people assume are well-known facts may go over my head... ) I have a mid-2009 MacBook Pro laptop. It is really bogging down (spinning wheel) to the point of being unusable... and I can't afford to buy a new computer. (Besides- I treasure my dvd/cd player which the new ones don't have.) I have 2 questions: 1) How can I get my computer to respond better and stop spinning its wheel as often? 2) Am I able to upgrade any components to increase the machine's capabilities to closer match contemporary specifications? Yes, it has been wiped/reformatted at a place in Cagayen de Oro, Mindanao, Philippines which helped some but not entirely. I work in many countries lacking good electricity, therefore the machine has turned off due to battery drain countless times. Can components get old and overused- slowdown but not die? Processor: 2.26 GHz Intyel Core 2 Memory: 4 GB 1067 MHz DDR3 OS: 10.8 (I tried Mavericks but it bogged down the system too much) Graphics: NVIDIA GeForce 9400M 256 MB Serial #: WQ923ULY66D Any help is much appreciated. Thank you!
