Windows XP System

Ok, thank You... Sorry for not mentioning that earlier. It's a 1.3 Ghz machine (or pretty close to that) 10 Gig HD, CD, DVD. I'm not sure what a mobo manual is. As for what it's doing, it will run maybe for 10 minutes and then shuts itself down. Always! (Very frustrating) The temp I saw last night was
CPU Temp was 132F and the System Temp was 100F and the RPM for the fan was about 3700-3800. Do you think I might need to replace or add an aditional fan?

Thanks!

It sure sounds like heating problems although your temps are high but not that high - and your fan speed is low but not that low - all depends on the outside temp as well.
My computer sound comparable to yours and I have lots of hardware - my CPU never gets above 100F - at the moment my CPU is 80F - inside the case it is 70F and in my office 60F. And there always seem to be that 10F between each of the readings. My fan speed is 4300rpm but comparing fan speeds is like comparing apples from oranges.

"mobo" is slang for MOtherBOard - your mother board manual along with the technical spec should list min/max temp which vary greatly depending on the motherboard make and model - try your motherboard web site or this site for a guide-

however these are usually high temp and from what I have seen lots of people have heating problems way below these so called max temp.

Things to consider:-
1/Are these the same temps you been getting from the day you bought it
2/ Have you added more hardware. - this will increase the load on the power supply - see this site to see if your power supply has enough power

3/ It maybe a power supply problem so check that the power supply fan is running and that your voltages are what they should be.

4/ If you have an external graphics card this could be over heating as well - so try and give it some air as well - you can move other PCI cards away from it.

5/ Open your case and put a fan next to it to see what difference this makes - Your outside temp maybe high and you dont have enough air flow.

6/ If necessary take some hardware off - such as CDROMs, other hard disks and PCI cards.

7/ Give your fans and mother board a good dusting and try and tie all leads in a bundle to allow air flow.

If it is heating problems then hopefully doing the above may levitate the problem - and we can then talk about steps to cool things down permanently
