Desktop reboots randomly

My pc reboots randomly without any warning or error. So, i checked the event viewer and found this : Microsoft Windows kernel power event id 41.


My specs are :

Pentium dual core e5700

integrated gpu

a 400w psu.

how old is your psu? is it bronze rated? sound like your psu is malfunctioning.

About 2 years old. And no i don't think it is bronze certified..
