My emachine shuts itself off, fan working ok, help help

The machine boots itself up fine i'd use it for maybe 4o minutes then it suddenly looses power. id wait a few minutes and id power it back up and it would shut down after another few minutes about 10 minutes. if i leave it off for a few hours it will run a little longer. ive just put a new fan with heatsink, the fan runs fine at start up and continues to run. the yellow light on the front seems to blink alot but im not sure what that means. some one told me its the power supply but im not sure because it does turn on the machine. it doesnt seem to overheat, but it did overheat before so i installed the new fan. please help me id appreciate any advice.

    hi guys thanks for the quick responses, well here it is i went into the system bios and this what it has for settings.

    cpu shutdown temp 85c/185f

    smartfan temp 55c/131f

    tempature tolerance (c) 5

    im not sure if those are the proper settings and if thats causing the problem. i then checked the temp and these are the reading

    i also checked the heat sink and its on correctly. should i change a setting. please advise. thx

    that heatsink fan is brand new, i just installed it. it runs perfectly, the one i had before was making some funny noises and not running. it seems to be in excellent condition. before i changed it i could feel how hot the pc would get, now it doesnt get as hot since i replaced the heatsink. it doesnt seem to how when it shuts itself off. could it be given bad readings. should i adjust the bios temps.

    thanks again

  • CESAR COLLAZOS Apr 20, 2009

    it seems to be running the right way, clockwise. i dont beleive there is anyother fan, this is the only one i see in the casing. is their a way to speed up the fan speed. it doesnt seem hot in there at all. before it was very very hot in the casing. thanks again.

    sure i can get that, dumb question on my part, but what is the fsb speed.

I think the problem is with your processor heating. just download the following utility and see that the processor temp is not going above 65 deg. if so then check the heat sink. your fan is not correctly placed. also when replacing the heat sink did you correctly put the thermal interface material.

check your cpu heat status with this tool...
http://www.cpuid.com/hwmonitor.php

if the heat is very high then try to replace the heat sink or see that it is fitted correctly

Hi there. When you turn on your system, enter the BIOS setup screen. Depending on your BIOS, you may have a section that tells you the PC Health Status. If you do, you can check what temp your processor is, and it may even let you adjust the warning temp, (it may be set too low). Some BIOS's will shut down a machine automatically if this temp is reached, to save the integrity of the system.

Yes, you may have a faulty power supply. Try testing it with another and see if the same thing happens. Also, make sure that your power supply is connected to your motherboard properly. Easiest way is to just disconnect it from the motherboard, check for any bent/broken pins, then just click it firmly back into place.

If you need me to clarify anything, just post a comment.

    Can you re-list the readings you took of the temps, please. They haven't shown properly.

  • Timothy Farley Apr 20, 2009

    You CPU temp is quite high, and your Fan speed is quite low for that temp. It could be that your heatsink fan is sticking.



    Open your system case, look at your heatsink above the CPU. Is it caked in dust? I would imagine it is. Clean it out. Just be careful of your CPU. Make sure you have disconnected the power lead, and you and the pc are not touching anything that can conduct a static charge. To be even safer, take out the heatsink (if you can), it'll be easier to clean too. Once you have done this, put it all back together, turn it on, and check what speed the Fan is running at.



    Let me know how you get on, and let me know the results.

  • Timothy Farley Apr 20, 2009

    If the heatsink is brand new, it seems really strange that it's only running at just over 2300 rpm On a CPU running at that temp.



    On the readings you listed, you only 7 degrees of heat left before the system will shutdown. That's not alot of leway. You can increase the CPU Shutdown Temp, but you will run the risk of a CPU meltdown. I doubt it is giving false readings, but it is possible.



    One thing I'd like to ask, is the CPU fan spinning the right way, pulling the air away from the CPU? I know it sounds like a stupid question, but I have seen this done. Also, are you running any case fans?

  • Timothy Farley Apr 20, 2009

    I think there maybe a program or 2 you can download to regulate the fan speed, but I'm not sure. Normally you can't change it, as the BIOS senses the temp, and then increases or decreases the fan speed accordingly.



    Under normal circumstances, I would suggest updating your BIOS, but in your case, DON'T do it. If you lose power at any point during the update, your motherboard will be rendered useless. The average temp inside a system is between 27-32 degrees. The reason I ask about case fans, is that, although your case temp is fine, you could run a case fan or 2, which would drop the temp, and in turn, drop the temp of the CPU.



    Can you tell me what motherboard you are running, and in your BIOS, can you tell me what FSB speed you are running at? Also, what speed is your CPU?

EMachines eMD620 suddenly shutdown and not boot anymore


When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.

I have an e-machine T2792. It boots up fine then runs for 10 to 20 min. then shuts down. Could this be my cpu going bad? Thank You Scott


CPU, the motherboard and the rest of the chips in it is subject to wear and tear. This is in addition to the high temperature it is operating with. The sudden shut down is cause by a failure of one component (usually the Processor) who's burned out.

1 Answer

Starts up fine after couple of minutes its shut


Your system sounds like it is either overheating or has a bad power supply If you remove the side panel on you desktop and look at the fan above the processor, it should be running at all times. If not your fan has blown and you must replace it. Please find out what version processor you have before making a purchase, as there are many different types of processors and fans.

Another issue could be poor circulation or inadequate ventilation. Hope this helps.

Good Luck!

Hello, a friend recently brought me a Presario c700 asking me to fix it. When I inspected it, it has occured to me that the entire thing looks completely fine, inside and out, I've checked this thing with...


What I recommend is you remove everything you could possibly remove from the laptop (HDD, mems, cd rom, wifi cards, etc) just to check if it will turn off even when it's not booting or posting. Try turning it on with just the charger and WITHOUT the battery and see if it stays on. If it doesn't, then most likely the mobo itself is the problem.

Check on the processor installed inside the computer's motherboard, it might be loosen and make sure it is properly locked. Also check for the fan. Make sure the cpu is properly ventilated to avoid overheating that might cause the shutdown.

Bad capacitor(s) on the motherboard can cause this problem, corrupted BIOS maybe... try flashing BIOS.
Probably the CPU if your not getting any error code beeps on startup.. NO Processor for the BIOS instructions thus no Beeps !
