(NT) Sounds like an overheat issue.
Sounds plausible -- now where do we go.
1. Okay -- why would it do it when not "doing anything". I've sat and used it for 8 hours straight but as soon as I leave it alone it dies. I'm not arguing, I'm just puzzled. (I did use a very good thermal grease when I installed the Cpu/heatsink fan. I don't rememeber the name but it was silver and I bought it from the local computer store)
2. What do we do to fix it? At this moment cpu is 106.7 F, fan speed is 4440, and pwm temp is 82.4. The case has a side panel fan, and the fan on the power supply is working. I think I'll leave the monitoring program up and see what happens when I don't touch anything.
In the event that you did not know
those temps for the CPU aren't even close to being too hot.
Are you sure that the settings for shut down in the BIOS are set way too low????
I checked the bios
Bios is set to shutdown when it reaches 258F. I updated the bios and changed the behavior from "smart fan" to dumb fan and that has helped.
I'm still not sure it is shutting down due to overheating -- I just know that when I leave it alone for 5 minutes or so the temp starts spiking by 30+ degrees.
Thanks for the great ideas.
That is way too high a setting
If your AMD and mobo are fairly recent it should be shutting down by the time it gets close to 70C [158F]. I would set the warning to about 61 to 63 C [142 to 145.5 F]]. I do not think that you have been getting close to that.
A 30 degree F increase is 16.7 degree C increase. For temps we must be sure what scale we a re using.
The weird thing is why it spikes when not "being used".
Do you have a graphics intensive screen saver running?
Check to find out what tasks are running in the background.
Got any of these programs running that shares your free CPU time for listening for signals from outer space or cancewr cures??? Not kidding, I just forgot what they call them.
Seti at home
I was running Seti at home and Einstein at home as a screen saver but have stopped them until this little problem gets fixed. So right now there is no screen saver in use.
I think it's definitely a power regulation problem -- see next post.
Thank you for your help, this is about the weirdest problem I have had in seven years of building systems. I learned something new...;)
You reported in another
post, the readings from a monitoring program. The setting for warnings in there have to be looked at for temperature. Possibly that program is causing the shutdowns. What program is it???
I am only discussing temperature. If some of the voltages are out of spec, then power supply replacement is certainly in order. A reasonable tolerance on the nominal power supply voltages, [the 5 volt, 12 volt and 3.3 volt] is +/- 3%.
And, again, why it spikes when not in use is not fully understood by me. That is, UNLESS the smart [not so smart] CPU fan slows down drastically when no activity is detected. Did the spiking cease after you changed the fan mode???
No real changes..
I didn't start using the monitoring program until after the machine had been shutting down for several days. Program came with mobo ad is call Abit eq. It is set to shutdown the machine at 75C cpu temp.
It still spikes after changing the fan settings-- it is just a slower upward curve.
According to advice I received from another member, I took a gander at Tomshardware and based on what I read there I do beieve it have something to do with the power supply. My computers syptoms were described and evidently AMD boards don't have a power regulator to protect the CPU if the power supply is wonky. While in use the power levels out but while idle it causes the cpu to overheat... Others who purchased this fan/case combo reported problems with the power supply.
A new power supply is not that expensive, I'll pick one up next week. Until then I'll just shut down the machine when I am not actively using it since the temps and voltages stay good while I'm playing with it..
Thanx for the info and good luck
with the new supply. It is sad that so many power supplies that come with a case are crap.
I always buy the case sans power supply and buy a good supply separately.
Another genius diagnosis -- how do I fix it?
I left the montoring program on and just sat and watched it. As soon as I stopped using the mouse, the cpu temp climbed from 106-112F, then the system seemed to catch it and it went back down to 108F. After a few more minutes the temp started climbing again. It was at 123F and climbing when I jumped in and started using the system again. It's now back to 106F.
I want you to know you're brilliant. LOL. Hopefully this problem has an easy fix???
Tell more about the heatsink/fan and..
What heatsink paste or pad you used. Does the CPU fan work?
Heatsink fan works
The monitoring program shows it runs from 4440 to 4850 rpm and I can visually see it turning through the clear side panel. Heatsink brand is Ultra / Socket A/370 / AMD Athlon XP up to 3000+ / Ball Bearing/Aluminum Fins / Copper Core / CPU Cooling Fan purchased new and conencted directly to the mobo. The thermal paste was spread evenly on just the center chip, leaving the green parts uncovered.
Said heatsink has to be "just right" sitting on the CPU.
There are other issues such as airflow in the case. That's what we remove the case cover until we sort out that the machine is in tiptop shape.
Also, a less than monster power supply can be an issue.
This case was sent as a replacement for a cheaper and worse one. (I now solumnly swear I will never try to save money by buying a cheap case....) I read the feedback on in and about 50% of the posts mentioned the power supply being bad either right out of the box or shortly thereafter. The monitor program is throwing errors due to the "vcore" and cpu....

I'm thinking I should go ahead and get a monster power supply since I have about a 50% chance this one is faulty. If that doesn't work then should I replace the cpu fan? I can also install another fan at the back....
Can't guess, but ...
I always leave the cover off until I know the heat can be controlled. Also I have yet to buy anything under 450 Watt since... it costs no more and while I know nothing we've built uses that much... they lie about the numbers.
Articles galore at tomshardware about that issue.
I have a direction to go in now....
It's strange having a toddler computer who needs my attention or it will throw a tantrum....Oh well, it's only a week old -- hopefully it will grow up soon!
Tomshardware is a great resource
Thanks for pointing me there -- I saw my problem and it is related to power supply being "wonky" (my words.) AMD boards don't regulate for the problem so temp spikes when system is idle...
I'm a poor college student until next week when the money fairy comes. LOL -- so will go buy the most reliable power supply I can find then. Temp and voltages are good as long as I don't leave machine alone...so will shut down when not using it...
Check up HAL
Try this pages & see if HAL is correctly installed & not damaged. http://www.kellys-korner-xp.com/xp_haldll_missing.htm & http://www.annoyances.org/exec/forum/winxp/t1006151611 If it's damaged or not correct working in any way, you probably should see something about it in the logbook. Start/All programs/Accessories (I hope that's the rigth word)/Administative tools/(Loggbook) Check all 3 logs to see if there's anything about this HAL. HAL= Hardware Abstratcion Layer. This is the "guy" who is responsible for your hardware & thier powersupply & so on...
Thank you for this idea --
I checked the logs -- nothing regarding HAL. I had to go into the logs a different way then you mentioned but I got the idea. I tried the repair console, the first time the computer crashed just as I was typing in the commands. The second time I did a fixboot, and it died while trying the scan. I don't think I'm going to get out of spending more money on this problem...
Lonely Computer???! Computer shuts down when left alone
I have had this problem also, have you tried the following steps?
1. Right Click on your desktop and go to properties
2. Click on the screensaver tab
3. Click on the settings tab under 'Energy saving features of monitor'
4. Set them to
Power schemes - Always on
Settings for always on -
System Standby - Never
Turn off monitor - Never
Turn off hard disks - Never
hopefully this should fix the problem you are having
Great idea -- system more stubborn
I swear I'm dealing with a toddler computer!
I did adjust the settings as you said. Temp dropped to 94F and stayed there for 5 minutes while I touched nothing and watched. After 5 minutes the cpu temp spiked to 120F over the course of 2 minutes...after typing this message it has dropped to 105 and is falling....weird.
Thanks for your reply.
Win XP? Try turning off the hibernation mode
Hibernation mode has cuased some reboot and shutdown issues wth some of our systems in the past.
Right click on desktop
Screen Saver tab
Hope this helps
Thank you -- we think alike...
This was one of the first thing I tried.
Still fighting the toddler computer..:(
Go to your control settings and click on the display settings. click on screen saver setting and at the bottom of box where the energy saving settings are click on the settings. click on all three boxes and enter never. click on apply
Unfortunately, what you have here, i believe, is a faulty motherboard. I had the same experience with a Shuttle motherboard. No fewer than 7 people who build their own systems have tried to get that turkey to work, to no avail. It's a bummer but you know sometimes, crap just happens. Try to get some compensation.
I haven't been thrilled with abit anyway -- any reccomendations? I'm willing to ditch the mobo and the power supply at this point....
I'm not a hardware guru but...
Could it be that the CPU fan and the case fan are plugged into the wrong place on the motherboard? They might just need to be swapped.
That would explain why the CPU fan thinks it's a smart fan.
.. I had it too! I'm sure the fan is plugged into the correct place. Tripple checked it! I guess I get to throw a bit more money at this system. I'll chalk it up to experience -- I have a lot of pricey items in my "experience" ledger. LOL
(NT) mini-doug. Most newer CPU HSF's are smart type.
Change the power supply
Change the power supply, trust me, nuff said
