CPU fan speeds acting strange


I had this machine built in January of 2003. In January of 2004, the motherboard overheated. I have replaced the motherboard and the machine will be fine and then all of the sudden the machine will automatically cut the power. I went into the bios and observed that one of the cpu fans was running from 4000 rpms and then would drop to 1500-2000 rpms. Of course the temperature would shoot up and the machine would automatically shut down. I replaced the cpu fan and it seems to be running stable. All of the other fans in the unit seem to be running fine as well. Nothing has changed in this computer for a year other than adding software or deleting software. Do you have any idea what could be wrong and how to fix the problem? The local computer store is at a loss.

This question was answered on April 15, 2004. Much of the information contained herein may have changed since posting.

You have replaced the motherboard, as well as replaced the faulty CPU fan on the new motherboard.

If you are still having problems with power cutting off You can check to make sure the power supply is properly secured to the motherboard as well as all the drives.

Now, the other thing is, depending the software you are install, the issue could be whether or not you have enough memory and or hard drive space You need to make sure that the present configuration of your computer can accommodate the softrware you are adding.

you must do this even though you are also deleting software.
