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..
