[QUOTE="BigDWeav, post: 1539939, member: 231720"] MacBook Pro 15,1 (late 2008) 2.4 Ghz, 4 GB, 750 HDD, Lion 10.7.5 My machine has started some unruly behavior. It started to periodically freeze, mouse control becomes erratic (selects and drags everything it touches, left button does not work, etc), After reading several posts and using the DriveDX utility to check my hard drive, I thought the problem was my HDD so I replaced my HDD with 750 GB WD. I then thought the problem was heat related and downloaded a copy of istat pro to check temps and fans. Fans are both running at about 2000 rpm seems normal. CPU is heating up to 75 deg., which I am told is not outside the normal range. I thought the issues could be caused by low memory but the last time the system became unresponsive, I had 2GB of free memory. I recently cleared my system caches and did an SMU reset which resulted in no changes. I used Time Machine to restore the system when replacing the HDD. If the issue is software related, then I would have copied the bad files onto my new HDD. Any other troubleshooting suggestions I could try. [/QUOTE]
