System randomly rebooting

[Sicone]

My system has been randomly rebooting for the last coupe of weeks. Having search the forum as best as I can, I have updated from 9.10 to 11.1 u6 but it hasn't resolved the problem.
I can't see anything in /var/log/messages (posted below - I know there are a couple of unreadable sectors but those appeared after the rebooting started happening), there is nothing in the IMPI event log and there doesn't seem to be a consistant time of day that it occurs.
What else I can check?

Have you monitored temps?

500W Corsair CP-9020059-NA/RF PSU

Was this a new supply to this build?

I have updated from 9.10

How long has this been running?

I know there are a couple of unreadable sectors but those appeared after the rebooting started

Probably want to address those after the rebooting issue is cleared up.
I have seen bad power supplies cause reboots. That is probably the thing I would look at next. Do you have another power supply that you can test this with by swapping it out?

Yes

Since Feb 2015 - Updated to 11.1 U6 on Saturday

Agreed!

Don't have one to hand but I guess this is a good suggestion

Getting close to four years, it might be time for a power supply.
If you are going to buy a new power supply, I suggest taking a look at this guide before you go shopping:

Thought I'd come back to mention that my system has been up for just over 2 weeks without any reboots since changing the PSU, so I think it's safe to say it's been resolved

That is great.

Did you address the hard drive issue yet?
