weird restarts when compiling

[Aggelidis Nikos]

Since i can't buy a new PSU today... I kept testing:

i tried compile


and i got a reboot again:

this time i checked /var/log/messages and i have this:

...

i also installed xmbmon to measure temperatures... i haven't seen
anything above 60C so i guess it isn't the BIOS rebooting the computer
due to cpu temperature..
