Rockystar Posted January 18, 2014 Share Posted January 18, 2014 Ok heres the story. I have an acer aspire 1830t. I had an intel i3 330m processor with original intel HD graphics. I had mavericks up and running with graphics working. The motherboard went south so when i purchased a new motherboard i upgraded to an i5 520um. Now all the hardware is the same with the exception of the i3 to i5 change. I however can now only get the laptop to boot mavericks in safe mode. When i try regular mode i get a kernel panic and no matter what flags i use i get the same kernel panic. Below is an image of the kernel panic and a dump of my system info from CPUZ. Any ideas would be great. Thanks LITTLEGUY.html Link to comment https://www.insanelymac.com/forum/topic/295393-i5-520um-hm55-chipset-safemode-only/ Share on other sites More sharing options...
