Hi ! I'm running 10.6.8 on an older macbook (maybe 2007 version). About two weeks ago it restarted for no reason. One week later this occurred again and since then has become a more and more frequent occurrence. I can almost guarantee it will re-boot if I do one of the following: - open to many applications or internet browsers - plug something into the usb port after it's been on for awhile - unplug my power adapter (even though battery is at 100%). I've tried a few things such as holding down OPTION+APPLE+P+R when restarting. I've also reset the SMC. And I removed spotlight function. Some days the macbook will stay on all day and be fine. Others, I can't even open up an internet browser. Yesterday I worked on it for approx 8 hours in a row, left for 2 hours and when I took it off sleep mode it immediately re-booted on me. I purchased extra RAM years ago so it shouldn't be lack of processing power. Below is also the most recent CONSOLE report. here: http://pastebin.com/D5udyp8J My console report is about 50 pages long from the last day so I've only included the most recent stuff. Any help is greatly appreciated. Thanks.
