The mac screen goes black and appears completely dead. No response if you use the back button to try to turn the iMac on. Only method of restarting is to unplug it and leave it for at least 10 min then plug back in and switch on with back button.
Yesterday I tried to remove AVG and the looking at the latest crash report the unistaller crashed at 17.57.
( I appear to still have a disc image of AVG left).
This did not appear to effect the rest of the system at the time. The whole system died when trying to upload a photo to DP review. I cannot see a crash reports for this or any Kernal panics. In all messages the last message was at 21:54 there were some messages with errors leading up to this. I have posted them in case it helps. Also I do not know why it is trying to look at my car insurance document. I was not trying to look at it at the time.
