Hello, It seems that my MB(unibody 2.0Ghz) has some problem. I recently reinstalled leopard (and some softwares). It takes a little bit more than 2 minutes to boot. Worse comes with Windows 7 beta. I tried both 32bit and 64bit versions. It takes more than 5 minutes to boot! I saw some guy showing some comparison of boot time on youtube. It seems that Leopard should take < 1 minute and Windows 7 takes < 2 minutes (with the same hardware!). My MB takes around 3 times more than other MBs. Where should I start? I recently ran memtest and it turns out to be okay. HDD S.M.A.R.T also reports 'verified'. I'm not sure what would be the next step. Thanks in advance.
