I own an early 2008 iMac running Snow Leopard. A few months ago, it started getting a little buggy and running slow, you know, things you would expect from a computer thats now 2 years old... but then it started freezing and giving me "kernel panics". Of course, the first thing I did was install VirusBarrier and remove any and all viruses it could find, and I repaired the disk and disk permissions and ran all the diagnostic tests from the install DVD. Then I left it unplugged for a day, upgraded the memory from 2 GB to 4 GB, and did everything a second time. After all that, everything seemed to work just fine. Now it seems to be starting all over again!!! This time the virus scan only picked up a few Windows viruses on an old external hard drive and repairing the disk, disk permissions, and running diagnostics turned up nothing. I've done everything I know to do, short of taking the thing back to Apple! Right now, the main issue is this bug at startup thats really just freaking me out. Linked is a video of what happens. The apps that run at startup are BumpTop, HughesNet Status Meter (as of last month), and Brother Printer Utility. http://dl.dropbox.com/u/14131544/VIDEO.MOV Any help would be appreciated. Thanks.
