Unwanted Windows Shutdown possibly due to CPU overheating

[Uncle John]

I have over the past few days found my PC shutdown in the morning. A number
of maintenance tasks are done every night after midnight and I can tell
roughly when the shutdown happened because a scheduled backup at 0400 AM has
not run. Computer boots without any hitches, except Heartbeat asking what
was the reason for the shutdown, and there are no errors in the Event Logs.

My System is briefly:

DirectX 4.09.00.0904 (DirectX
9.0c)
CPU Type Intel Pentium 4,
3133 MHz (23 x 136)
Motherboard Name Gigabyte GA-8PENXP
(5 PCI, 1 AGP,
System Memory 3584 MB (DDR SDRAM)
BIOS Type Award Modular
(09/06/04)
Video Adapter NVIDIA GeForce 6800
GT (256 MB)
Monitor Iiyama ProLite H510
[20" LCD] (140510002169)
Audio Adapter Creative SB0240
Audigy 2 Platinum Sound Card

I suspect that though the machine is very well cooled there may
nonetheless be an overheating problem because when working hard the CPU is
nudging 78C. I would like to know how I can LOG the temperature.(I can
watch it with MBM 5 but do not have a log capability.)

Shutdown ? - Normally, A system halt will cause an automatic reboot.
Unless you've disabled that option in System Properties. The fact that
you find it "Off" sort of eliminates a BSOD. A power loss (Brownout)
can leave it in a power off state if BIOS is configured that way. Does
the PC work off a Universal Power Supply ?

78 C is too hot, What is the quiescent temps in your PC ? How many
fans and monitors are active ? Everest Home edition has a good hook
into Thermal monitoring. What wattage PS does the PC have ?

 

[Uncle John]

Room ambient temperature is 22C, Motherboard 25C CPU Quiescent 60C. Power is
supplied through a large Smart-UPS with one hours reserve power.
It does not restart because the fault completely shuts it off, it is not a
system halt because it is logged off. The system has six fans and a deep
gigabyte cooling fan on the processor Mind you this chipset has always run
very hot when it is working hard, (I had to replace the Intel fan because it
was so noisy). the Gigabyte Alarm point is 80C.
I could be wrong about the shutdown being due to heat but I would love to
have a temperature log to know!

Hmonitor provides a monitor for this Gigabyte motherboard. It can
be downloaded from http://www.hmonitor.com/. There is a technical
note regarding a temperature offset. But for short-term use, it can
be run as a demo.

Is there a chance that one of tasks you run at night turns PC off after its
completed?
CPU wouldn't shut down OS when it's overheating. It would throttle down.
look for software called ThrottleWatch.exe
it has option to log CPU freq, temp, throttle and voltage. (created text
file with data)

Thanks I have tried Hmonitor in the past and had a lot of grief with it,
every time I restarted the PC it asked for a new license. I do not remember
that it had a log facility and it wasn't fully functional until registered
for about $30.
I will give it a shot again.

 

[Uncle John]

No, then nighttimes task are all maintenance and of the kind that if they do
not run successfully because PC is down they will run when it starts up.

I will look for the software you suggest ThrottleWatch.exe

Hit F5 and it will start logging. Go to options and it will show you where
file is written. You can also change destination

That is way too hot to be running that CPU! No doubt it's hit 80C and that
probably shut it down. I don't understand why it is running that hot. Have
you tried reapplying some thermal grease and reseating the cooler?

Cheers.

Thanks for your comments

I have put an S&P extractor fan on the PC enclosure venting to the exterior
and the CPU is now running around 66C at 50% load which I hope will fix the
problem.

Still running too hot.

I checked with Intel and was told not worry as the chipset should have no
problems up to 80C! They claim that if the dual CPU is getting too hot it
auto throttles and if this is not happening the system is OK.
I have logged the throttling and it is zero over 24 hours.

The NVIDIA Geforce 6800 GT is showing an ambient 39C and core 58C (shutdown
threshold 120C)

So I am going to have to leave the CPU running 65-70C

Thanks again for your help.

Just in case I missed, what do you have for heatsink? Stock Intel, or
aftermarket?
I use Thermaltake Sonictower with 12cm fan in middle of it.
12cm fan for intake and 12cm for exhaust.
P4 (660) 3.4GHz overcloced to 3.7GHz I get temp idle 45C load 49-50C

 

[Uncle John]

I have a Thermaltake XaserIII and a Gigabyte 3D Cooler Pro which is similar
to yours.

Duh, of course they told you that. I wonder why? Hmmm, maybe because they
sell cpu's? Do some googling and you'll find how much the lifespan of a cpu
is reduced by running it hot. Why would you want to push this cpu to that
temperature when any decent cooler PROPERLY installed should run at a
significantly lower temperature than what you're reporting now?

 

[tjoy]

Recheck your heatsink. Make sure its settled correctly, also reapply thermal
paste.
Remove old one, use rubbing alcohol to clean surface (cpu and heatsink)
Drop small amount on CPU and use credit card to spread it.
Don't overdose, use your judgment. Best way to test is to mount heatsink,
and then lift it off and see how paste was spread. (after that redo whole
process)
Don't use fingers, as it will contaminate paste with oil from your
fingers!!!
Some paste brands will need few days to "burn-in" or "cook"
What that means, after few days CPU temp should drop.
Like I said, I overclock my CPU. It's only air-cooled and keeps temp under
50C.

You are both right that it should run cooler and your comments have prompted
to look at it another way. I closed all non-essential processes in Task
Manager and the CPU temperature dropped to 48C. Some further investigation
revealed that a process called StatusClient.exe was using about 50% CPU time
on one CPU and when stopped the temperature dropped to 47/49C.

This process belongs to a new HP Color laser printer Model 2550Ln and likely
monitors the supplies status: I will now have to investigate the problem
with HP.

However my CPU problem is solved and thanks for the help.

Wow, another crap from HP. Well, I'm glad you solved your problems, well
partially.

Is that one of the laser printers the EFF exposed this week as leaving
secret dots on every page printed so the US government can track what
printer was used to print something?

If the printer manufacturers are in cahoots with the government invading
people's privacy like this, one can only imagine what companies like
Micro$oft have been doing in this area. Mind you, we'd never know as all
their software is proprietary and the source code is hidden.
