Comment 17 for bug 153031

I think I resolved my issues. I feel a bit stupid and I'm not sure how it happened as I'm not an overclocker nor do I ever condone overclocking. I took at look in my BIOS and somehow the RAM/memory timings and speed settings had changed. I changed the RAM timings to something more conservative like 5-5-5-12 and 1066. There was also a setting that was set to "Turbo" which I changed back to "normal" and so far so good.

If you're having spontaneous hang ups, lock-ups, crashes, kernel panics or just plain weirdness with your computer despite fresh OS installs then I suggest you take a look in your BIOS and tone things back a bit with the RAM settings and stop overclocking anything if you are.

Ferrazrafael - I'm not sure you'll have these settings in your BIOS since you have a laptop but it's worth a look. If you don't have the specific timings/speed settings then make your BIOS load the "Fail safe" settings and see if that doesn't help.
