Why is my computer running slow with new upgraded logic board
I'm working on a friends computer, i ended up having to replace the logic board. i opted for on suggested by ifixit that had a faster processor on it. i don't know how fast the computer ran before but compared to my own mac that's 2 years older, it's running really slow.
especially boot time, it took a minute and a half to boot compared to my 31 seconds. I've already repaired permissions using disk utility. then i took the HD out and used my sata connector and using drive pulse de fragged the HD.
reinstalling and boot up and still slow. just wondering what steps i should take. and what other people might think.
