Inserted a cd-r that was full of camera pics--system froze,no cursor no keyboard response.
Waited 10-15 mins but still no go-resorted to reset switch on PC. After this I was unable to complete the boot process--message on screen asking for administrator pass word to continue.
Ended up re-installing and using live disk to delete most of the dot files then went ahead without reformatting /home. Success!
This time I have enabled Admin Password!
Anyone else suffered this problem or know of possible cause??
