This could be caused by a number of different things. Such overheating, virus, hardware failure, etc.

Does this happen often? Or has this happened before?

this is the first time

You can try disabling the auto-reboot feature of Vista by:

1. Go to Start > Control Panel > System
2. Go to Advanced
3. Under the Startup and Recovery section, click Settings...
4. Under System Failure un-check "Automatically restart"

If there is something wrong, instead of restarting by itself, a blue screen (BSOD) will show up and display a specific error message that could be causing the computer to restart itself.

While you're at it, you should monitor your system's temperature and scan for viruses.

Are those temperatures for load or just idling?

 

[nitro1]

well i downloaded the link u gave and saved it to my desktop and then clicked on it and thats what came up....

if i had to guess i say idling bc the numbers changes every sec but not by much though

Oh ok, then the CPU is a bit warm at 50+ to 60C when it's just idling. So probably when you're doing something more demanding on the CPU, it will probably reach 70C or higher which is overheating. 20-40C is acceptable for idling and 50-60C is good for load.

Try cleaning out the dust in your computer, especially the CPU's heatsink.
