Need help with CPU please think it's over heating

My computer makes a loud humming noise when the system first boots- real loud

I have a feeling that the CPU may be over heating

Debian comes with a program named resource monitor I don't know much about computers or how to determine which processes should and should not be running I took a screen shot of the diagram and went to post it here but photo bucket will not host the picture an error message comes up saying that the file is not supported I do not know of any another place that will host the picture.

The CPU is jumping up and down from 2- 9 and 11 percent with a red line floating across the screen I would guess that maybe 20 programs are running right now I don't want to terminate any processes from running for fear that I might stop something that is needed to make the computer start.

I have been using Sarge Debian on this PC for over 6 month


Any suggestions on what to do will be appreciated very much

If your CPU usage is not exceeding 11%, then no software measures will solve overheating. This sounds like improper cooling, if it is truly over heating. What makes you think the cpu is overheating?

I have no idea it's just a hunch

I've been using Sarge Debian,on this computer for 6 months now and never had any problems with it what so ever, until now.

I had a hard time installing Debian in the beginning must have installed and then reinstalled Debian somewhere around 20 times until finally getting it right is it possible that there is to much space on the hard disk from the previous installs or that maybe a bug caused the hard disk not to erase the old Linux os-s that were installed previously.

I apt-got a program named lm-sensors to see if it would give me detailed information about the processes that are running on the computer but the program did not show up on the list of applications and I can't find it or know how to get the program to start. I tried typing lm-sensors into the run box and it is not opening up I don't know what else to do.

I'm really concerned about this loud humming noise I feel like this is a ticking time bomb just waiting to blow up my CPU.

Any suggestions on what to do will be appreciated the noise keeps getting louder and louder

The program you actually run to retrieve information from the lm-sensors suite is plain 'sensors'.

From your descriptions, however, I seriously doubt this has anything to do with CPU temperature. If the noise is when you first switch on the computer, my guess would be the power supply and/or its fans.

After installing lm-sensors I think you had to run something like sensors-detect (maybe as root) from a terminal. After that I used gkrellm to read the temps. However I do believe the temp readings in the BIOS are the best indication of the actual cpu temp and fan speed.

I had the same problem you mentioned and it was caused by a faulty cpu-fan....resulting in a fried cpu. So if its the same problem you'd better get that fixed.

ps Have you had any lockups or immediate shutdowns? If you havent it could be a case fan or something else.

In any normal situation the CPU should *never* overheat.

Try cleaning the fins of your CPU fan. Always overheats when the fins get clogged up with dust.

Or check if the fan is running normally.
