Hallo,
I am using a 15" MacBook Pro early 2008 with 2,5 Ghz C2D. Beside a 160GB Intel SSD the hardware remained in original configuration, including the battery. Furthermore I am using Mac OS X Lion with all updates. I am a bit brief on this since I can't boot my Mac OS X partition at the moment (see below) and access the data I wanted to post here.
Since a couple of weeks I had a recurring problem. In the beginning the problem occured only every now and then. Since two days the problem accurs very often (after a few hrs). The problem is as follows. In normal use in Mac OS X the screen starts to flicker, show coloured lines across the screen or grey blocks. Shortly after (<3 sec) the system stops working at all and only a forced shut down (pressing on button for 5 secs) helps. When rebooting the apple logo appears and the grey progress "bar" turns. Then the screen freezes and reamins frozen. However one can hear programmes like skype starting (I also heard when someone wrote me) and the fan speed increasing. I checked with "cmd+v" when it stops and it stops at different steps. When turning the macbook off and on again the problem presists. After numerous shutdowns the OS finally boots all the way. First I thought that the battery might be the reason since it hasn't been changed so far and it started to tell me that I have to change it soon, but the problem remains with removed battery. I also have a Bootcamp partition that works fine so far (used it already a couple of hrs to check this).
I have a backup so I considered a reinstall, since the problem seems software related to me. I wanted to check first if there are maybe any other easy solutions or steps I should try before reinstalling though. So far I didn't find someone with a simular problem.
Has anybody a good idea or a hint what I might try first?
Thanks a lot for your help!
Florian
