ubuntu restarts for no reason
 

sometimes Ubuntu will just randomly restart, it happens about every hour, does anyone have any idea to a fix?

Hardware overheating?

i dont think so i have the antec 900, i added a fan, so now it had 5 fans, so yeah lol

I also have that problem.
1st time i want open movie.avi, i try 2-3 time , it keep restart. next day, it do not restart again but i try open file.mp3, it restart again ..........

Bad RAM, probably. Leave memtest86 running overnight.

i have 4 gigs of ddR2 all exactly the same, corsair,

the sound will also turn off sometimes

Two top reasons for behaviour like this are faulty RAM and out-of-spec PSU. Did you run memtest86 as I suggested? Let me guess, you didn't.

i havent had time

You've got it wrong. Your time is not needed, memtest86 uses computer time. You can sleep meanwhile.

i know, im 14 years old, i have school to wake up to, my parents are split, so when i said i havent had time recently i was serious lol
