Hi there! I'm new to this forum and I will try to explain what's happening to my iMac lately. I am really upset and desperate about this issue so please HELP!!! I've switched to mac around December and everything was working so fine till 5 days ago. First I can say I have the 24'' 3.06 processor 4 gb of ram and 500 gb hdd from which 40 gb free space. 5 days ago I've noticed that when I was watching movies with vlc the program was pausing, chocking and I was soLving the issue by ff a few seconds. The next couple of days was the same and I've noticed as well that mac os x v.10.5.7 was loading slower and slower. Last night I've restarted and the startup screen came up with the apple logo and the little dots circle that was showing it's loading. Waited more than one hour and nothing happened. Restarted with the mac os install disc and went to disk utility. Done the disk verify - all ok, no problems. Did the permissions verify and found some of them but after I did the repair permissions I did another verify and was finding the same problems. Anyway shut down everything got upset. Restarted this morning and I took like 10 min to load up and finally the icons showing up. But now evrything I do the beachball is keep spinning and when it stop and I try to click something it's spinning again. For ex I've deleted an icon from dock in 3 min, i've openned a finder window in 5 min, I'm trying to install onyx.dmg and I've clicked like 10 min ago and it's still loading. (( Btw I have the windows as well in another partition and everything is working fine there as it supossed to work. Can anybody help??? I dunno what to do... Was thinking to reinstall mac os from the disk but I don't have anything backed up! On the cd install says that I can reinstall mac os as duplicate and will put the old one in a separate folder or something but I still don't know if will erase all my data! Can anybody help? Thank you.
