I don't know howthe situation occured, all I remember is iTunes failing on me and word encountering a problem. So I restarted my macbook (1.8 core duo) instead of running disk utility. Now when I restart my computer it goes to the desktop and my finder app folder appears. If I were to click on it it would beachball makign it take longer than it should to scroll. Applications does not seem to start, even after right click>open it won't even bounce in my dock. I tried quicklooking for Disk Utility to repair permission and the problem persisted. It could be a RAM problem, is there a way for me to check the RAM at startup, again I'll be unable to get to about this mac. In the past doing a reinstall fixes everything. I no longer have a working disk drive in my laptop, so I would be forced get a external drive. I have 10.6. would a dvd drive possibly fix the problem?
