Screen scrambled and freezing up during bootup (no hardware issue)
When I bootup my iMac I get a scrambled screen and after a few seconds the screen freezes.
At first I thought this was a hardware issue but after reinstalling the OSX on a USB drive the OSX booted up normally. I cloned the defceted partition, reinstalled it and everything is working. The cloned one on the USB drive is still scrambled during boot.
Although I have my data there are a few programs I cannot get back so I would like to get this issue resolved. Doies anyone have any advice?
