Over heating valiant 671 dp

My system is overheating. i think the cpu fan is inoperable. i also noticed the power supply was extremely hot. i was wandering if the system overheating because of a bad fan can also cause the power supply to be overworked because of electric load change durng overheating? i would appreciate any insight. thanks.

The power supply and laptop are both hot because your fan isn't working. You'd know if it was working by the whirring sound it would be making. Send it in for service.

My acer aspire 9300 overheated and donno what to do


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

I turn the laptop on but it immediately turns off within seconds


1. First step is to check if the laptop is overheating:
  • Does the bottom feel very hot to the touch
  • Is the CPU fan not spinning up
If it is hot to the touch and the CPU fan is not spinning up, this will cause the system to overheat and shutdown as a safety feature. In this case the fan would either need to be cleaned or replaced.
2. Failing hardware can also cause this (i.e. a failing motherboard, CPU, Battery, Power Cable, internal PSU, etc.):
  • Did you notice any system freezes or slow down prior to this happening
  • Have you noticed a sharp decline in battery life
Try disconnecting the battery and then only use the power supply cable to power up your laptop. If the problem still occurs, then reinsert the battery and remove the power cable and attempt to start up the laptop with only the battery inserted.
3. In some cases this can be caused by a malware (virus) infection. The infections that cause this can sometimes be remedied, but usually require expert assistance and the remediation process is very specific to that type of infection.
  • Does it get to the first splash screen (i.e. the BIOS splash screen)
If it doesn't get past (or even to) the BIOS splash screen (usually a Dell Logo) then that would point towards it being a over heating issue or Power issue.
Having said that, it's more likely a hardware issue (i.e. dead to dying Battery, failing Power cable, broken CPU fan, etc.) instead of a virus infection. Make sure to check the first two steps to get you closer to properly troubleshooting your issue.

Laptop seems to be overheating


Best thing to do, take a can of air and where the air vents are, blow the air into there and it should remove any dust or dirt that could be blocking the way. If there is debris in the way, then that would cause the fan to run louder then normal cause its taking more for the fan to cool off the laptop.

The absolute best way is if you could take the laptop apart and where the heatsink is on top of the CPU there could be a big piece of dirt blocking the air vent and where the cpu heatsink sits. You could physicially remove it.

Either way if you go thru both of these steps and the laptop is still overheating then you know at that point the motherboard is bad and would need to be replaced.

Since recently i notice am hearing the sound of the fan on the laptop spinning louder than usual. the computer these days is very hot all over. the heat that comes off it is extremely hot.


i think ur system fan cable need resolder. for this it cann't run freely or the other things for many dust in ur fan it can run freely. so check these if everything are ok then plz change ur system fan. u computer shut down bcoz when ur processor doesn't get sufficiant air then it become so hot and ur pc will off. its so dangerious.

Light comes on, flickers once after 15 seconds then after 10 more seconds shuts off.


Could be a loose or shorted wire connection on the motherboard to the power supply.

Or your power supply fan may be non-op and causing system overheating and the system to shut down.

Acer 5570 southbridge overheats and shutsdown


well,if you r able to get to bios then check power managment sction and reduce CPU speed and try to deactivate one of the peripherals that is responsible of thi shorting out= over warming.


as long as the southbridge chip over warms every time you turn on you laptop thats mean the S.B is facing a shorting out on it IC.

you can clean underneath/surround it.

Could me many things. Let's think. I installed an antivirus once that would get stuck scanning some file, the CPU-- the main processor in the latop-- would go to 100% and would get so hot that the fans would go crazy cooling it down. It could easily shut down if left on all day from heat.

Another laptop I had- I read on the support boards (it would get hot and the fans would be very loud) that the thermal last between the CPU fan and the CPU would degrade, causing the heat dissipation to decrease-- the heat of teh CPU was not being wicked away through the paste to the CPU fan. Boom- the laptops would shut down from too much heat.

Did you install any new software lately? If no, it could be a hardware problem like I mentioned above.

Third, a friend of mine had a gateway laptop that would get very hot-- he could hardly use it. It was a loose/faulty graphics card that would get very got, causing teh fans to go on, and then the computer to **** down.

Many of these hardware problems are tough to solve over email like this because you need technical knowledge. Further, most of these require the unit to be sent in to fix, really, especially in the case of laptops which are tougher even to get at than desktops.

Call the manufacturer, as they might be able to talk you through a fix or sending it in. Even if it costs $130 bucks, it's still not the 500-600 you need for a new computer...

Good luck!
