G'day all, Over the last month or 2 my Macbook of a little over 4 years old has been experiencing some problems and I want some opinions on whether it is time to move on to a new Model. My laptop is used for university work which mostly consists of typing documents and so on. I do a fair bit of video editing and short film making (which is now not possible as it can't even handle iMovie, even with every other program closed) and I also use it for browsing the web, iTunes and every now and then a bit of Photoshoping as i also am a hobbie photographer. Specs: Early 2007 Macbook running Snow Leopard 2GHz Intel Core 2 Duo 3GB 667 MHz DDR2 SDRAM 320GB HDD 1st issue: Screen Spasm 2 maybe 3 times a week I'll be in the middle of something and this screen will appear accompanied by a flickering noise and the only way of stopping is to hold and shutdown the computer. Any ideas?? 2nd Issue: Freeze The computer will freeze just like any other would and if music is on at the time the sound sounds like when your CD's skip except it doesnt stop until you shutdown. This has been occuring once or twice a week for the last month or so. 3rd issue: Sound fuzzy Every so often i'll be listning to music or watching YouTube and the sound will skip a few times then go all fuzzy and static, there is however a reasonably quick solution to this....pause whatever ur listning/watching, leave the computer for a minute and then resume, usually works. My big question is what will it take to fix these issues and at what cost? Is it worth the expense or will i be needing to fork out money for a new computer soon down the track either way? If i can fix these problems will I be able to continue my video making/editing or is that something that will not be possible on this laptop from this point? Would really appreciate some assistance/advise? Thanks for reading!
