Minecraft Shuts Down my Computer

[Sketchy]

So basically, I run MC and after about 10 seconds my computer reboots.
I have no idea why, but it doesn't happen for anything other than MC.

Windows XP 32-Bit
512MB RAM
2.66Ghż processor.

Maplestory's on server maintenance so I have absolutely nothing to do

I don't have any idea why this happens. Maybe go to the minecraft forums page

There is your problem. Minecraft is a huge memory hog.

yeah upgrade ur ram
with that little amount of ram it will take forever to load anything

get as much as possible and u'll see a huge difference in computer performance

Thing is, I was running MC with no lag about a month ago.
But now it's crashing my computer.
