Ahh... Only managed to last 288 hours, 35 minutes. Have to reboot after a major update - IE8, Office 2007 SP2, etc.
After my "forced" reformat and reinstallation of Windows Vista, it seems more stable now. Am now at 249 hours and 48 minutes...
Yup, my notebook I think the heatsink is probably stuffed with dust right now 48-50C during idle with fan constantly at full speed even though the ambient temperature here is low I wanted to clean it but I don't have any tools to open up my notebook. 557 hours so far.
It already has SP1 pre-installed when I got it, but I haven't updated it since 725 hours 10 minutes so far.
No wonder you have been running non-stop so long - you didn't update!! I had to reboot several times for new updates. Mine's now at 562 hours, 20 minutes and counting!
Damn! That's a record! I'm only at 630 hours and counting... I wonder if I will hit 818 hours before I upgrade to Windows Vista SP2.
