A340n stopped responding. rebooted, fan extremely fast and ** reponse from computer. I opened it up just to look....Best Buy said it was the fan mounting. There was a contact **t being made between fan and motherboard(MB) therefore computer told fan to work harder to keep it cool.
How difficult is it to replace this mounting is there a step by step guide to help me or shpuld I pay smeone to do this for me?
Thanks, Steve Ward

The fan is a function of how hot the cpu and gpu units are getting on the motherboard. If the fan is running fast it means the heat from the motherboard components is not getting passed out of the enclosure. Get some canned air and blow out the dust from all the vents around the computer edge. You could also get a laptop cooler to put under your laptop.
Normally when the CPU fan gets very loud it is because of an accumulation of dust. It cant revolve fast enough to cool your CPU so it will want to close down.
You need to open up the computer and blow the dust off the fan blades, preferably with an air spray can. Report back when you have done this!
Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard
Fans normally have three wires on them 1 black negative, 1 red positive and 1 yellow which feeds information to the bios about how fast it is spinning and temperature. Although the fans are working one of the fans senser has gone probably on the cpu fan, it might be worth looking inside and checking the cables are all plugged in properly, or you could buy another fan.
A fan that no longer works will cause a heat problem. While it may not cause a complete failure, it can cause some strange things to start happening. Your best best is to shut the PC down and remove the cover. Restart the PC an determine which fan(s) has stopped working.
At this point, you can either 1) contact IBM for a replacement fan or 2) remove the fan yourself and google the name and model number of the fan to find a direct replacement and either order online or 3) visit a local PC repair shop to buy a replacement fan that matches the defective one.
Buying direct from IBM will probably cost the most, but will be the exact type needed for your PC. Buying locally will probably be cheaper and faster, but may not be an exact replacement unless it is the same model, etc.
When calling IBM you'll need the computer model, serial number and any other identifying numbers on it for them to help you out.
have you tried to check if it switches off in safe mode? and also have you tried to check if it switches off in the bios, if it does not then it is an operating system issue and you can try reinstalling the operating system ( XP, Vista) if that too fails it could be an issue with the heatsink or the processor.
That has to do with windows programs. Try doing a system back up if that doesn't work wipe the hard drive and put windows back on it. I have the same system and that has happened to Me. That is what I did. Now it works fine.
Have you got the latest bios firmware already installed? That's a good place to start with a problem like this. Otherwise there is a special 3rd Party app that might be able to control your fan thru software control. Either way start with the bios update first and post back if it doesn't work.
It would be helpful to have the model# of the board.
If you look on the board itself you can look for a 2 or 3 pronged connector coming off the board that is labeled fan.. Reguardless, if there are any fans in your case already then you can just buy a power splitter ( like this one ) and then hook it up that way.
