I don't know if this has been brought up before,but I'm having problems with Panic always seeming to come up when I boot up my iMac. I have had Snow Leopard installed when it first came out. I honestly don't know why it keeps going into panic mode. I've used the disk utility from the install disc & I've used system restore twice(right now is the second time I used system restore). I obviously am not computer savvy. If someone was to ask me if I could recreate the problem causes the panic,I can only say,"every time I boot up it seems like." Sometimes I'll have three panics in a role with each reboot. It is the most vexing thing & I end up putting cursing rants into the comment part of the report sent to Apple for each computer shut down due to panic. I just want the damn thing to work without headaches or "Panic."
