I've been seeing this in the past 2 months. 3 so far. There appears to be a pattern. After a cold boot the computer seems to work for about 13 minutes then restarts on its own. After that, the amount of time it stays on seems to reduce more and more until it is rebooting even before windows loads. Also rebooting in safe mode. I am pulling my hair and mind out (not literally). No amount of research has helped so far. Malware scans have not helped. I am wary of system restore since the computer might reboot right in the middle of it, but I have done that for one of the computers, successfully, and that did not solve the problem. I have not specifically removed Windows updates, but the system restore would have done that for me right? Opened one of the computers that had this problem and blew out dust. Reseated and even swapped memory chips. My current specimen is having it's main board replaced today, by Lenovo. My fingers are crossed. Any ideas would be cool.

yes, I have seen that, with desktop computers.
in that case, it's usually too much dust inside the box.
solution : open the box, get the dust removed, and you are settled for another couple of months.

Could be any of the following:

1. Too much dust not allowing proper air-flow
2. Defective power supply or main board
3. Defective heat-sink fan or lack of thermal paste on the heat-sink

Event viewer only says "hay, your computer rebooted abruptly at 0800 hours!". That's all it says. My current specimen is a new computer - less than a month old.

You can try booting a live CD like Knoppix to see if the problem is hardware or software.  I'm leaning towards the hardware side but if the live CD runs OK without reboots then its a Windows problem.

install speedfan - to monitor the cpu and video temperatures
if they get too high, dusting out may not be sufficient - you may need to replace the heat paste on the cpu

check also if ALL fans run ok : CPU, PS, and case
