Hello everyone. Long time lurker, first time poster in the iMac section. Anywho, I own a 20" 2.66 GHz CD2 iMac with 4 GB of memory and a 320 GB hard drive. Recently, I have noticed that my iMac is lagging a bit. When I say lagging, I mean that when I go to shut it down, it stalls and nothing happens (i.e. the dock and icons disappear) but I have to end up doing a hard shut down. Furthermore, I sometimes experience the spinning ball of death. Quite frankly, I am a bit confused as to why I am experiencing negative actions from my fairly new machine (purchased in the summer of 2008). I am not doing any extensive programming or anything of that nature; only general web browsing, paper writing and music listening I did a bit of research and reset the PRAM and repaired permissions. I think the next step will be to repair the disks but I will have to wait since I am at college and my disks are at home. Any ideas or same experiences? Any help would be greatly appreciated. BTW, I do not think it could be bad RAM since I purchased it from OWC and had good luck with them in my CD 2.0 GHz Macbook with 2GB of memory.
