Hi all,

For the last week or so i have been having unexpected shutdowns with my PC.

At first I thought it was due to the inevitable weekly xp update but then i noticed that the shutdown would occur midway through a virus scan, so i ran the scan again in safe mode and cleared the two items it found, hoped this had solved the problem but two days later the pc shut down again.
I reinstalled everything from scratch after formatting the harddrive, but sure enough the pc shut down again, this time in the middle of the day whilst on idle.
I did the usual, cleaned out the case, checked the ram, checked the fans and then ran an enviroment monitor with sandra soft, I notice that the results indicate random peaks in the psu temp, in the range of 6-20c averaging at 16, could this be a faulty psu or is this caused by the gulp effect of the psu on the current?

The temp guide shows two peaks which reach as high as 35c average rose to 20

The power supply is an enlight rated at 300w, crap generic rubbish but came with the system

OK back again i'm afraid, system just shut down again.
the system was running in idle again and i turn away, it shuts down.
I noticed that the display goes off first (sleep mode no imput) then the whole system shuts off, no error messages and no error on restart. when i turned the system straight back on i hear 2/3 beeps from the board and nothing happen except that the light comes on at the front, no fan, drive sounds.
5 mins later tried again and pc booted up normal, ran enviro check and cpu temp is 41/42 average, board temp constant 28 but psu temp started at 56 before dropping to 28 and now fluctuate between 28 and 42. sorry to keep updating but thought that might give you more info

If you are getting temperatures that high is more than likely that Windows is shutting down to protect itself.

Download Speedfan and report back to us the temperatures. After you report back to use we will look deeper into how components may not be installed correctly, fans not spinning or clogged up with dust.

ok.
Temp 1: 32c
Temp 2: 48c
Temp 3: 19c
HDO:33c
Temp 1: 51c
anything else that will help let me know.

I've given the program a little time to run and temp 3 (psu) is reporting as follows:
Last: 26
Min: 0
Max: 37
Mean: 24.8

the other temps are pretty constant +/- 3C

carsey

Two things immediatly strike me:

Temp 2 at 48C and The 2nd Temp 1 at 51C.

If you feel confident open the side cover and look around the fan and heat-sink for dust and also that the fans are spinning freely. Of course do this while the computer is UNPLUGGED from the wall and you are properly grounded. Also, another good idea is to point a desk fan inside the case and check the running of the system. Does it still shutdown?

MONSTERMONSTER

opened and cleaned the system best i could yesterday. i am currently running it with the case open in a cool room. fans were spinning fine with out intrusion.
A little dust still in the case but major areas are clear
Fanspeed is only reporting speed for 1 fan and that is running at 2909-2860, other fans are spinning, i can see and hear them

Hi,

Give the Sensorview program under my signature a try to see what the comparision is on temps, fans speeds, and voltages. Some times a sensor will just not report correctly.

After you have done that, take the side off the computer, blow a house fan in there on the CPU area and see if it shuts down with that running.

Post back with questions/concerns.

MONSTERMONSTER

ok, i took the computer to my workshop and used the airline to blow duck and crap out of the fans, power supply and from the heat sink. temp1 is currently 26c according to fan speed although its only be running a little while.
I will give the system time to warm up and then run sensor view before reporting back

here's the log, as you can see the cpu temp is fluctuating from 54 - 15c

Hi,

To be quite honest, except for the three I have marked, these are considered average normal temperatures. In the instances I have marked with a red mark, then the other components are still consistent with good temperatures. Therefore, I would suspect maybe on these three a glitch in the sensor (not reporting correctly) because the others are so consistent. I have given you both Sensorview and Speedfan, so run the other program as a double check and post those results back.

Did you get much dust out of there and are you still getting shutdowns? If so, have you tried the fan trick?

MONSTERMONSTER

system has not shut down since i switched it back on at 4.15
currently running it open with a deskfan blowing in there and still getting similar readings.
Didn't get a great deal of dust out but then i tend to clean the inside of the case faily regular so not too much builds up.
I have kept sensorview running and put the cpu under full load stress and still the temp tops out at 63, bottoms out at 9. these results are consistant with those provided by fan speed

speed fan log agree's all down the line with that posted, within a margin of +-1c

Tumbleweed36

Hi,

I still think you are getting some readings that are inconsistent. However, if your temps go up to 63c with a fan in the side, we need to look at another issue.

If this were my unit, I would take the Heatsink and fan off the CPU, clean both as per the Thermal Paste Instructions under my signature and put it back with Artic Silver 5. That should lower the temps again for you and you are not far out of the ball park at this time. I always use 63c as the max I permit a CPU to be at under-stress. I just won't run them at a higher temp although they are capable of slightly higher temps. Therefore, you need to be in the 50c range or less than 60c without that fan on the side. I like them even lower than that and my rigs never get over 50c regardless of the stress it is under.

A rundown that might help:

> Make sure you have a fan in the back pulling hot air out of the case.

> Make sure you have a fan in the front pulling in cool air.

> If you have a top fan, it should pull hot air out of the case.

> If you have a side case fan, it should pull cool air in.

> Your heatsink fan should be blowing down on the heatsink.

> Move ribbon cables away as much as possible from the CPU area.

> Use Artic Silver 5 instead of the factory thermal pad.

This should give you some things to check.

Post back with questions/cocerns/answers.

no shutdown since 4 yesterday, temp are pretty consistant in the range of 10-40 although occasionally rising as high as 60. the comfusing thing is that it is not hitting those temps whilst under strain but when idle, maybe a faulty detector.
I am going to take yourr advice re thermal paste when i have the funds

Thanks to all for the help, now if i could just stop my internet connection going screwy
