Hi I was given this computer by my brother not too long ago and recently it has been giving me the problem at start up saying that my CPU fan is Abnormal and caused some problems booting my computer, now to only have my computer randomly shut off after it sounds as if my fan is running at a very high speed.

I dont know all of the stats of my computer as it was given to me and I dont know how to figure all of them out.

all I have for now unless someone can tell me how to find what kind of motherboard I have..

the stars I know is that im running on windows XP home edition service pack 3
intel pentium 4, 2.80 GHZ
2.79 GHZ and 0.99 GB of ram.
i got that from my system information.

if anyone has any ideas that would be appreciated....

Read this post, it sounds like you have the same problem.

Temporarily turn off the temp auto shutdown in bios and it probably won't shut down your computer and you will hear the CPU fan go to very high RPM and then slow down to almost nothing. Due the bios thinking the CPU temp is going from 5C to 125C all in a matter of seconds.

Your temp monitor on your mobo is most likely messed up by a bad capacitor.

I wouldn't turn off the auto shutdown!

thats a bad idea even if your the sensor is dead have a look at the sensor programs

use coretemp to look at CPU temps

That CPU temp is WAY too high. Follow the directions Dai gave you and clean off the old thermal paste and put some new on there. Please use Artic Silver 5 if you can and follow the directions very carefully:

Applying Artic Silver Thermal Paste

yes when under load the cpu will shut itself ,when it thinks that it is going above the required temp.....if you have to use it then use some small program that dont put it under stress..



but using now will reduce the life of the processor.

remember to only use about the amount of a long grain of rice for the thermal paste.

The paste should be a very thin layer
