Hi guys, the problem is that my computer shuts down randomly. For example I played Sniper Elite III and it just shut down . My gpu is not overclocked but CPU I5 2500K is overcloked. My motherboard is Asus P8P67 Deluxe B3. I ve tried to run OCCT software test, maybe someone of you uses this program and I chose to do power supply test. After 8 minutes it stopped automatically because it detected error and this is what I got zip file http://www.filedropper.com/occt . Can you look at the photos and tell me is this because my cpu is overclocked or this is because of other reason. In windows event viewer it detects Kernel Power Error 41. All temperatures are fine, tried to do logging with Aida x64 and when I open log it seems everything ok. Thanks guys for your help.

UPDATE:

I just was on my desktop and was holding F5 button and the desktop was keep refreshing and the pc just shutdown. But before it went black I noticed on the OCCT graph that the cpu speed was going up and then it shutdown.

UPDATE 1:

Just checked CPU with CPU-Z and the speed of CPU keeps jumping even if my pc is on idle. The same on OCCT the speed keeps jumping and jumping and on the line where it says overclock sometimes it shows -50% and then jumps back to +31%

EDIT..
On second thoughts, possibly a PSU problem, check the PSU for dust clogging it up, if it is clean the PSU could possibly be on it's last legs

ok just turned off cpu overclock and did test again and it seems fine, but my question now is why everything was ok before with overclocked cpu and now suddenly its start to shut off? just confused now... by the way I do dust cleaning regularly for all hardware inside my case so I believe is not dust clogging. I will do another test just to make sure it was overclocking problem

Are you in the UK?
I have had 6-8 degree higher temps the last few days due to ambient temps (20+ degrees here today)
That few degrees extra could be enough to push a stable OC just over the edge.
Also after reading your OP again the fluctuations of the CPU could certainly be the PSU or even the VRM's on the MB

How long have you had the MB and how long have you been running it OC'd?
 
just try raising voltage a little see if stops the crashing
stuff can degrade over time

what was it overclocked to anyway?
 
4,5ghz
CPU Manual Voltage 1,350V
DRAM Voltage 1,6V
VCCSA Voltage 1,0V
VCCIO Voltage 1,103V
CPU PLL Voltage 1,890V
 
can u still get 4.3/4 stable with 1,35 or nup?
what you back to now?

i think 1.4 is safe them cpu if u rly want 4.5 but id just drop it down a little see what its stable at now ><

just work it up slowly again

A couple of years does seem like nothing, but truth is components do fail and there is a reason most companies only offer 1, 2 or at most a 3 year warranty.
If you want an interesting read check out "planned obsolescence"

My mate runs an Electronics firm and has informed me on numerous occasions that certain "big name" companies are well known to use underrated capacitors in their TV's :)

I will try to play with voltages again and will text again the results. Now I'm back to factory reset to 3,3 Ghz
