The dreaded kernel power 41 issue

Checked northbridge temps?

If it were a problem like faulty RAM or HDD, your more than likely going to get a BSOD. Not getting one leads me to believe its more internal. I.e overheating (north bridge) or shorting. (Disconnect those FP headers)

Ok so I'm pretty sure its not the northbridge overheating I am sometimes there when it reboots and when it does so the northbridge has always been under 50oc.. About the potential shorting. I did notice that when i'd mounted the board I had used mostly hex type screws but there are a couple of smaller rounded ones, I've ordered some more hex screws as thats always what i'd used in the past. I had none of those cardboard washers but I haven't seen those for years so I'm assuming that's fine.

However let me try to explain something, i noticed one thing. around each screw hole of my motherboard were silver dots, that the screw heads kind of rested on. however on the holes these dots did not go all the way round the hole (this is on a few holes and some others have a full metal ring around them as i've seen previously). I'm wondering if the screws are the issue so here is a picture of one of the suspect screws

Oh and when you say FP headers, I take it you mean the power switches etc and usb. One thing to note is the bios will shut down the mobo if the NB hits 110 but I've never seen it go over 70 EVER ( i beleive Northbridge is SPP)

Ok so I was playing borderlands 2 today (great game) and i'd been playing for two hours and my machine rebooted in game.

The temps immediately after this were

CPU 31oc
CPU #1 / CORE #1 34oc
CPU #1 / CORE #2 34oc
CPU #1 / CORE #3 30oc
CPU #1 / CORE #4 34oc
SPP (Northbridge) 52oc
MCP (Southbridge) 55oc
GPU 33oc

All pretty normal... grrrr

I had this for months.

Removed braided cable extensions, nothing ever since.

I take it you mean your 12v cable extension.. I've removed mine just to check that wasn't faulty (indeed I have an entirely new PSU in there).

The only other thing I have in there are big fans that are plugged into molex connectors which are indeed on extensions, you mean to remove those also ?
 
Currently I have removed the smaller less "traditional" screws that hold my mobo in place and replaced those with traditional hex screws (only 2 of them).. honestly if its that i'm gonna be so ****ed off :)
 
Ok so it wasn't the screws causing it.. Windows was sitting there at the desktop whilst I was downstairs. I'd played borderlands 2 for about 2.5 hours then stopped, everything was cooling down (from the massive 36 degrees it had reached) and the NB and SB were at around 50oc at that point.

I went downstairs was 45 mins into a tv program and hear the machine reboot.. checked the logs 41 power issue, meaning it just rebooted.

I am now going to disconnect both all front panel headers, usb, power everything and see if it still happens with that.

This utterly sucks aside anything else my cpu has never been so cool in the six or so other systems I've built myself :( Was scares me is if I buy a new mobo and cpu and it happens then.

I suppose the only other thing I can do is purchase an SSD load a copy of windows on that and see what happens with all other disks disconnected. if it doesn't reboot time to gradually introduce the other drives back and if still ok its my windows installation I suppose. Never has an issue been so drawn out :(
 
I'd totally missed the older bios version suggestion also will look into that if this latest round of stuff fails

I should mention that after the last reboot I did the following

1) Moved My HDD to a Higher bracket to ensure I could move my GFX card
2) Moved My gfx card to the other blue 16x slot
3) Removed the reset, power and HDD led headers
4) Removed all usb headers.
5) uninstalled gfx drivers in safe mode
6) uninstalled chipset drivers
7) reinstalled 5 + 6

ok so I know that's a lot but it goes hand in hand with the gfx card move which was redetected.

I like your tenacity lol. I had a freezing/ reboot problem once on my p4 system and it took ages to find out what it was and even then I couldn't figure it out, however I luckily tried loosening the motherboards screw a little and hey presto no more freezers and reboots. I doubt you ha e the same problem though.

Best part of a year this has been going on I tried lots of stuff before opening this thread, tenacity is forced by 2 kids and it being christmas, also I don't want to spend just over 500 quid for a new mobo processor and memory for it to do the same :)

I did however get a bsod today it may not be related but that pointed to stpd.sys which is a low level daemon for scsi passthrough used for daemon tools , i no longer have daemon tools and i also tried uninstalled stpd using the online uninstaller but it still hangs around.

Next step will be to run linux for 48 hours (the restarts are getting more frequent these days) and see if it still happens, if not its software related , whocrashed.exe did say stpd was causing issues. but hey it might not be that :)

The good news is I can reconnect the headers as its clearly not them (rebooted without them connected)

I ran Linux mint live cd after my machine rebooted in windows when encoding, lots of stuff in handbrake, and I started to encode the same stuff on the same disks in handbrake for Linux and no reboots, and I then ran prime95 and was browsing my root c drive which is a western digital caviar black, and machine rebooted, and which rules out windows as a cause

Temps on cpu were 50 and sb an nb were also about 50, all fans working.

Next thing to try is to install windows on a spare hdd and disconnect existing disks

Unless anyone has any more clues I will then be saving for new hardware.... What scares me is this may happen again after buying the new hardware... Opinions welcome on how you would now proceed.

I would be very much inclined to run a full scan with HD Tune, and watch the drive temperature also.

Yes amazing you said this I hadn't used HDtune but had done a seatools check, these tests are in progress will report soon.
 
I'd be shocked to discover what appears to be a fully functioning drive that passes tests is the culprit of a PC cutting out and restarting. Very shocked!

Try it out of the case on a motherboard box. Keep everything else in, just take the mobo and all things attached out in one go. Leave the PSU and drives in. Takes less than 5 mins.

it IS coming to that its harder to remove this mobo from the Antec 900 II because before I always had cases where the mobo tray slid out the Antec is fixed :( So it means taking cpu cooler off to get at the screws, nonetheless I will run these HD tests to be thorough then it looks like I'm going to have to do this. I don't have a motherboard box anymore but I take it any bit of cardboard is valid ?

I also like the fact you do judo hehe I'm currently 3rd kyu.

Quick question for you I know its early doors for asking this but is it possible that its because i'm using brass standoffs (they came with the case), might it be a good idea to have some plastic ones on standby ?

For those who wanted me to test my hdds with hd tune here you go :)

Congrats on the 3rd Kyu. Get your frustration out with a throws haha. Brass standoffs are fine providing they're mounted correctly.

If only you were local I'd have popped over and had a look myself. Very annoying issue.

Its really annoying :) its also intermittent so it can do it 3 times in one day or go like 1 week and never do it. Its never caused any damage and the system is otherwise rock solid for everything else.. (as rock solid as a rebooting pc is). As for the brass standoffs, there are nine in and they are mounted in the correct places which i confirmed when i stripped it all down, they are also screwed in properly Not loose)
