I have a Dell Dimension 4700 and I cannot get it to run quietly like I believe it used to when I bought it new. I switched out the PS and theres no improvement. The power supply has been putting out very warm air. The CPU/case fan easily gets kicked into high gear mode for any processing. That's when the noise starts. I have cleaned out the case very well and also cleaned out the power supply case. Maybe the CPU is getting too warm or maybe it got heat damage and doesn't run efficiently anymore, reason being, the CPU fan once failed to spin after I cleaned it with alcohol and the computer automatically shut down to prevent damage.
What could you suggest to fix this high gear fan noise.

Re: loud Dell desktop
Any fan that is making noise you would need to replace. There is also never a need to use alcohol to clean a fan. Some computer air or a light wipe down will do just fine. If you have any other questions let me know. Thanks, Lee

First to be check is your power supply. Used power supply or brand new ones, does not matter as long as it is working properly, with correct voltage and ampere rating. Check your power supply with a voltmeter. Please take note also the total watts you need.. If your power supply is running good, problems will go down the line, the Motherboard. Remove all devices (hard disk, cards, memory, etc) just the motherboard, just to see if the motherboard is working right. Your should be hearing a beep sound indicating that the board is alive. If yes, you may reinstall the rest of the devices you removed.
Windows XP requires a "bare-minimum" of 128MB of RAM, works "OK" with your 256MB of RAM, if you don't open too many programs at the same time, and if you close/re-open Internet Explorer about once an hour of usage.
But, Windows XP would be _much_ "happier" if you added 256MB or 512MB of RAM, because it is telling you ("available random access memory is low") that it is using all the RAM.
Add more RAM -- your computer will run much better.
Turn the machine off and unplug the AC power then hold the power button in for about 30 seconds to drain any residual power. Plug it back in and turn it on, when you see the Blue DELL word press CRL+ALT+D and this should run a diagnostic on the hard drive. If it runs ok you will get a pass or fail on the hard drive. If you cannot get the diags to run you might have a bad power supply or motherboad/processor. I would find a known good power supply and try it before the motherboard.
This is very common after a fresh installation of the OS. Simply go to Windows Update and run it a couple of times. Upon reboot, the system will detect your hardware and you'll be back in business!
