Problem
 

alrite ive had this problem going with my wc3 for awhile now, while im playing a game custom or bnet, sometimes my computer will just reboot for no reason, this doesnt happen with any of my other games, anyone got any ideas?

Insufficient wattage or voltage.
Add any new hardware recently?

EDIT: Actually there's another thing you could do, press windows key + pause, click the Advanced tab, click the Settings button under "Startup and Recovery", and uncheck the "Automatically Restart" box.

ive done that, and instead the game will just freeze , orignally this happened a year ago after i had just got done building my new comp, and i thought it was overheating, so got thermal gel and 3 fans in the sucker and the problem still happened, but for some reason after a couple of months the problem went away, i dont know how and here we r now with the same problem a couple of months later

i think ill take off auto restart again and give it a shot
