PC Randomly Reboots

gimp_hunter · 10 Nov 2013 at 20:30

Hi,

Hoping that someone can help shed some light on my PC troubles.

About a week ago, my computer suddenly began to restart randomly. At first, it was just once or twice, but now it's become very regular, but happens randomly. There is no blue screen, it simply powers off and then it starts back up again. More recently it boots into Windows and everything seems OK for 15-30 minutes and then reboots.

This also happens in Safe mode and has sometimes happened during start-up before the login screen comes up.

The only error in the log is that the system didn't have a clean shutdown.

Any help or ideas would be greatly appreciated.

Thanks

Spec:
Asus P6T Deluxe
Core 7 @ 2.66Ghz
24 GB ram / 16 GB / 8 GB (I've swapped/changed RAM to see if his was issue)
1x Samsung SSD 840
4 x Samsung in Raid 5

Windows 8.1 Enterprise

I had a similar experience a while ago, it turned out to be loose psu connector to my graphics card, so you could check that all power connectors are pushed fully home

Thanks for the suggestion, have double checked all the power connectors are pushed in, but problem has just happened again

Could be failing psu

Can also be memory or CPU memory controller voltage CPU vtt it might be labelled as

On my x58 I ran it at 1.35v with 6gb of memory

I've noticed under the hardware monitor, 3.3V and next to it, it says 2.917V (and is coloured in red).

Does this hint towards a broken PSU?

doesn't look too healthy

should show 3.3v constantly

It would also be worth checking temperatures.

Thanks for all the help and hints to solve my problem.

Received a new PSU today and all seems to be working fine
