iMac 8,1 Slowdown
My 2008 iMac 8,1 has 8GB RAM and is running on the ATI Radeon HD 2400 video card. The machine runs pretty much 24/7 unless I have to reboot which I do at least once a day.
It is running Snow Leopard and for whatever reason, after it runs for 5-6 hours, I have to reboot because performance becomes so slow that It's almost unusable. I have tried closing and reopening browsers, apps, clearing browser cache, doing a complete erase and install, restoring from backup and even running the utilities on the Applecare CD which never found anything wrong.
It has been in to the local Apple store twice. Once to monitor performance and run diagnostics (which found nothing) and a second time to replace the Hard Drive which I thought was the problem. Well, it wasn't and I am still having to reboot at least once a day.
Has anyone else experienced this issue and resolved it?
