My Intel Core Duo MacBook Pro 15" has been crashing more and more. Previously there were various types of screen-freezes. Now the screen-freeze is being followed by an auto-reboot, which suggests to me a serious memory fault. Auto-reboot is a 3-5 second freeze followed by sudden system reboot, that reloads the OS like normal. I have backed everything up and run Drive Genius programs to defrag and verify the drive, but the problems have come back. My current plan is to replace the hard drive. My question is: what else could be going on here? Can RAM or CPU chips be the of cause this? Is there any way to check that?
Screen-freezes include any of the following:
- everything but the mouse freezes
- everything freezes but no graphics distortion
- all graphics distortion (whole screen; couple times with trippy mouse tracer effect)
- all graphics fade to an eerie pale blue color (3 second fade time)
- Processor 2.16 Ghz Intel Core Duo
- Memory 2 GB 667 Mhz DDR2 SDRAM
- 100GB hard drive (profiler doesn't show me the model)
- This is the first generation of Intel MBPs; purchased new in 2006 I think.
